2121.0. "Opcode Vision Sequencer for Macintosh" by 4GL::DICKSON () Mon Sep 18 1989 13:14

    For $10 Opcode will send you a demo version of "Vision".  I got one,
    and following is the 8 pages of information contained in the TeachText
    files on the disk (in lieu of documentation).   I have run the text
    through Runoff so it looks better.
    
                           Vision Overview

                         Opcode Systems, Inc.
                 1024 Hamilton., Menlo Park, CA 94025
                            (415) 321-8977




This overview will give you some  general  information  about  Vision.
You  should  probably  read  through  it  once before playing with the
Vision demo.  Then, using MultiFinder, you can open this overview in a
word   processing  program  and  use  its  "Find"  command  to  locate
information about specific Vision features.

Vision  is  a  real-time  MIDI  sequencer,  editor,  and   interactive
performance tool for the Macintosh computer.

Vision is based on earlier Opcode Sequencers -  if  you  are  familiar
with them, you will feel at home because things are set up in much the
same way.  However, you will immediately discover that you can now see
your  music  on  the  Macintosh  screen  -  two  types of windows with
powerful commands for displaying and editing  your  data  (graphically
and as lists of events) have been added.  And, virtually every feature
which  was  unique  to   Opcode   Sequencers   (generated   sequences,
subsequences,  trigger  modes,  etc.) has been extended with increased
functionality to allow even more sequencing possibilities.


1  Events, Tracks, and Sequences

Vision allows you to record, play, edit, and store music  information,
and  some  other things like meter, tempo, and text.  This information
is stored in tracks - each track contains a stream  of  events,  which
can  be  sent  to as many as 16 different MIDI synthesizers.  For each
event, the track stores the time of the event, which  MIDI  instrument
is  used  to  play  the  event, and a description of the event itself.
Time is expressed in "metrical time":  the bar and beat in  which  the
event  happens  is shown.  For timing accuracy, beats are divided into
480ths of a quarter-note.  These tiny time slices are referred  to  as
units.

Tracks are a little like the tracks on a tape deck:  each one contains
separate  information,  but they play simultaneously.  A collection of
tracks is called a sequence:  it's a little like a passage,  or  song,
on a piece of tape.  Each sequence may contain up to 99 tracks.  Every
sequence also has a meter track  and  a  tempo  track:   these  tracks
contain  the time, key signatures and tempos which apply to the entire
sequence.

To stretch the tape analogy, you could say that just as you  can  have
several songs on one reel of tape, you can have dozens of sequences in
a single Vision file.  But you can access up to 26  of  the  sequences
instantly,  and  chain  them  together  into "play lists".  This makes
Vision more like a CD player than a tape deck.  In fact, Vision is  to

Vision overview                                                 Page 2


a CD player as a CD player is to a tape deck.


2  Recording and Playing Back

When you start up Vision, three windows appear  on  the  screen.   The
Control  Bar  at  the  top  is  used to supervise most of the play and
record functions of Vision.  The File Window at  the  left  shows  the
sequences  in  a  Vision file:  at this point only one, Sequence A, is
shown.  A Sequence Window for Sequence  A  is  opened  on  the  right.
Track  1  is  automatically  record-enabled, so you're ready to record
immediately.

There are many ways of recording music into a Vision track.  There  is
step  recording,  in which you can record one note or chord at a time,
and real-time recording, in which you record  a  MIDI  performance  as
time  passes.   In  each  record  pass, or "take", you can replace the
entire track; you can punch record, recording over just  part  of  the
track;  or  you  can  overdub,  combining  what  you play with what is
already in the track.

There is also a special type of  recording  common  to  drum  machines
called  loop  recording.   This  process of real-time recording can be
used to "build the groove":  each time through the loop (which can  be
set  to  any number of bars), you hear what you have just recorded, as
you overdub more parts over it.  You can  even  change  MIDI  channels
while in record.

You can specify a starting point to be used for  recording,  called  a
Punch  In  point.   Vision  will either wait until you play a note, or
give you a countoff, starting some number of bars before the punch  in
point, but not actually recording until the punch in point is reached.
You may also specify a Punch Out point, which will automatically  stop
recording when it is reached.

After recording the first track, you'll  probably  record  some  more.
Pretty  soon  you'll  have a sequence full of tracks.  You'll find the
Sequence Window provides the opportunity to quickly solo and mute  one
or several of these tracks simultaneously.  You can reorchestrate your
music by assigning different synthesizers  to  your  recorded  tracks,
even as they are playing.

You can experiment with  different  values  of  quantization,  if  you
didn't  play  your  music  in  perfect time, or with time shifting, if
you'd like to slightly alter their feel.  Each track may be named,  so
you can easily remember what's on it.


3  Editing

Once you have recorded one or more tracks, there are a lot  of  things
you may want to do to them.  Perhaps you played some extra notes where
your fingers slipped:  you can easily get rid of them.  Maybe you want
the   timing  of  what  you  played  to  be  more  accurate,  or  even
mechanically perfect - you can easily quantize it.  You might want  to

Vision overview                                                 Page 3


move  some  notes from one part of a track to another:  you can easily
cut and paste them.  Maybe some notes should be up an octave (or maybe
you  meant  to play minor instead of major):  you can easily transpose
them.

All of these operations (and more!) can be done  in  Editing  windows.
Each  editing  window  lets you see the music one track at a time.  If
your sequence contains several tracks you can easily switch  from  one
to  another.  If a track contains music for more than one synthesizer,
you can easily switch between instruments, or look  at  everything  at
once.

The Graphic Editing window provides the best view of notes:  they look
like  they  would  on  a  player  piano roll.  You can select notes by
clicking on them, and change them by dragging.

The List Editing window provides a more detailed  view  of  notes  and
other  Vision  events:   each  one  is  simply listed in chronological
order.  You can select and edit them by clicking and dragging,  or  by
clicking on one of the fields and entering a new value.

Both windows constantly display what is in  the  track,  and  what  is
selected.  If you make a change in one window, it shows up in another.
If you record into a track, the changes are shown as soon as you stop.
(If you step record, each note is shown immediately!)

Simple editing commands  operate  very  similarly  to  Macintosh  word
processors:  select what you want to copy or remove, choose Copy, Cut,
or Clear with the keyboard or the mouse; select  where  you  want  the
Clipboard to go, choose Paste (or Merge or Insert).  If you would like
to listen to the part of the track that you are looking  at,  you  can
select it, and choose Play Selection.  These editing commands work the
same way whether you are  using  a  Graphic  Editing  window,  a  List
Editing  window,  or  both.   If  you  select more than one track in a
Sequence Window, making a change in any of those tracks' Graphic  Edit
or List Edit window will affect all the tracks you have selected.

The Graphic Editing window also contains a Strip Chart.  You can  edit
note   velocity   or  duration,  or  any  modulation  event  including
controllers using a bar graph.  Editing is as simple as drawing a line
across  the  Strip  Chart  with  the  mouse:  this line can be used to
create, or modify existing data in numerous  ways  including  scaling,
adding, subtracting, limiting, and randomizing.

More advanced editing commands are also available.  First, there is  a
very powerful Select command which lets you enter a set of conditions:
all events meeting the conditions are selected.  After  selecting  the
events  you want, in addition to copy/paste editing, you can transpose
them, either from one scale in one key to  another  scale  in  another
key,  or  using an arbitrary map.  You can quantize them, entering not
only the resolution but other parameters which let  you  perform  less
mechanical  quantization (this edit quantization is in addition to the
real-time play quantization mentioned above).

Vision overview                                                 Page 4


After selecting a particular range of  time,  you  may:   reverse  the
order  of  the  events in that time, compress or expand MIDI events to
correctly fit the displayed barlines, with compensation for tempo;  or
automatically  generate  smooth accelerations of tempo to make a piece
of music fit a predetermined amount of time, as in film scoring.


4  Sequence Chaining:  Subsequences and Queueing

Vision is a "pattern-oriented" sequencer, which means you are able  to
record  several separate sequences and link them together into a song.
To do this, the first step is, of course, to record  several  separate
sequences.   As  you  can  see  in  the  File  Window,  each  sequence
corresponds to a letter from A to Z.   Typing  this  letter  instantly
starts playing the associated sequence.

To construct a song, you can record a string  of  sequences  into  one
track.   The  easiest  way  to do this is to get into Step record, and
then type the letters while recording the  track.   The  Counter  will
automatically advance by the length of the sequence you enter.

If you want to experiment with the order of several  sequences  before
you  chain  them,  or  if you want to play several songs in order at a
live performance, you can Queue them.  In Queue mode, typing a  letter
when a sequence is playing causes the letter to "wait in line" for its
turn to play.  As many as 16 letters may be waiting, queued up.   When
the current sequence finishes, the next one begins.

Once a sequence is recorded into a track, it's called  a  Subsequence.
At  that  point,  it  becomes  an  independent  copy of the letter-key
sequence in the File Window.  If  you  change  (or  even  delete)  the
sequence  in the File Window, the subsequence will be protected safely
in its track.  If  you  edit  the  subsequence  the  original  remains
unchanged.  A single file can contain hundreds of sequences, certainly
enough for playing a long performance without reloading (assuming your
computer has enough memory, of course).


5  Generated Sequences

In addition to normal "multitrack" sequences, Vision has  a  different
type  of  sequence  called a Generated Sequence.  As introduced in the
original Opcode Sequencer, a generated sequence has the capability  of
playing its events in any order, including randomly.

In Vision, generated sequences have been extended.  They give you  the
ability  to  record  a  series of notes in one track, at your leisure:
timing is not an issue.  A rhythm track can then be recorded  allowing
you  to  concentrate on the playback timing, instead of what notes you
play.  The generated sequence combines the  two  tracks,  playing  the
notes in the note track using the rhythms of the rhythm track.

Vision overview                                                 Page 5


The note track and rhythm track are standard Vision tracks  which  may
be  edited, and copied and pasted from a generated sequence to another
sequence, generated or not.  Also, the notes produced by  a  generated
sequence  may  be  captured  directly  into any track of any sequence,
where they may be used from that point onward simply as notes.


6  Live Performance

In addition to studio-based MIDI  editing,  Vision  has  a  number  of
capabilities   which   make   it   appropriate  for  interactive  live
performance.  First of all, as in the original Opcode  Sequencer,  the
MIDI  Instruments  provide  output mapping which makes reconfiguration
from one  MIDI  setup  to  another  easy:   each  event  plays  on  an
Instrument,  which  has  a  channel  that  can  be changed, even while
playing.

The Instruments in Vision go several steps further.  There are  32  of
them,  so  you can use all sixteen MIDI channels on both serial ports.
Each one can be layered, playing simultaneously through  up  to  eight
synthesizers.   Each  layer  gives  you  real-time  transposition  and
velocity scaling, so you can balance the levels of  your  synthesizers
without changing the tracks or the synthesizers.

The  Input  Map  allows  simultaneous  recording   on   several   MIDI
Instruments,  for  easy  real-time transfers from other sequencers, or
recording of MIDI jam sessions.  It also allows setting  up  versatile
keyboard  splits,  where  each zone on a keyboard may be independently
transposed, and assigned to different instruments.

Another live performance capability of the original  Opcode  Sequencer
is  the  ability  to  use  the  keyboard  to trigger sequences, and to
transpose sequences which are playing back.  The Input Map allows  any
zone  of  any  MIDI  keyboard to trigger any sequence, or to transpose
playing sequences.

Vision may be remotely controlled by the MIDIKeys and the Faders.  The
MIDIKeys   translate   MIDI   notes   and  footswitches  to  Macintosh
keystrokes.  Since most of Vision can be controlled by  the  Macintosh
keyboard,  this  extends  that  control to your MIDI keyboard.  If you
only have one keyboard, you can define a MIDIShift which can make your
keyboard control Vision only when MIDIShift is held down.

The Faders are used to control more  continuous  functions,  including
tempo,  and  velocity scaling of MIDI Instrument layers.  In addition,
each one can send a MIDI controller  message  on  any  instrument.   A
fader  may even be controlled by an external MIDI controller, allowing
continuous remote control as well.


7  Players and Queuing

Like its predecessor, Vision has nine Players, which can  be  used  to
play  sequences  independently.   Each  Player  has  its own Queue for
playing sequences in order.  And, any sequence can be set to start  at

Vision overview                                                 Page 6


a  particular part of a bar, so that when you type its letter, it will
wait until that beat "comes  around"  before  it  stops  the  previous
sequence,  and  starts  playing  itself, so you can interactively, but
synchronously, start any sequence at any time.


8  Synchronization

Vision may use either the Macintosh's internal clock,  or  it  may  be
externally synchronized to either standard MIDI sync (beat clocks), or
MIDI Time Code (the MIDI form of SMPTE Time Code).  This allows  using
it  to  add  "virtual  tracks"  to  a  real tape recorder, which might
contain voice and other tracks which are not easily  synthesized.   It
also lets you use it as part of a larger MIDI system.


9  File Compatibility

Of course, Vision reads and writes MIDI files, so you can easily  move
your  music  between  it  and  other  sequencers  or  music creativity
programs.  And it can transcribe any sequence into a notation file for
Deluxe Music or Professional Composer, and open those files so you can
play them.  (Unfortunately, the Vision demo  program  does  not  write
MIDI Files or notation files).


10  On-Line Help

Since Vision is a Macintosh program, you probably will often just  try
something  to  see  what  happens.  We have tried to make sure that it
does what you expect it to do in these cases.  But  if  you  ever  are
confused,  on-line  help  is  just  a  click  away:   holding down the
Command, Option, and Shift keys will turn the cursor into  a  question
mark;  then  selecting  from any of the main menus or clicking on just
about anything on the screen will open a window which  will  tell  you
about  what  you  clicked  on, and, in many cases, offer some tips for
using that feature.

We think you will find that Vision is a very powerful yet  easy-to-use
sequencing  environment.   You  will  probably  be  able  to work more
quickly than ever before.  We hope you enjoy the Vision demo,  and  we
hope you become a Vision owner.


11  Additional tips

Since you don't have a manual for Vision, here are a few tips to  help
you along.

First of all, almost anything on  the  screen  which  is  boldface  is
editable.   Just click on it:  you'll either get a pop-up menu, or the
cursor will change to thin arrows.  You can then type a value, or hold
down  the mouse button, and move the mouse up and down like a fader to
change the number.  You can enter MIDI notes using the MIDI keyboard.

Vision overview                                                 Page 7


Remember that on-line help is just a click  away:   holding  down  the
Command,  Option,  and Shift keys will turn the cursor into a question
mark; then selecting from any of the main menus or  clicking  on  just
about  anything  on  the screen will open a window which will tell you
about what you clicked on, and, in many cases,  offer  some  tips  for
using  that feature.  You should read the help for every icon in every
window.  The "Keyboard Shortcuts" command in the Help  menu  has  some
particularly useful tips.

The little whirly icon in many windows, called the Mogrify icon, opens
a  menu  with  important  commands  for that window.  For the List and
Graphic windows, it opens the Edit and Do menus.  Be sure to  look  at
these commands.

To select a sequence in the File Window, or to select  a  track  in  a
Sequence  Window, or to select an event in a List Window, click on the
black dot at the left edge of the  window.   It  will  change  into  a
hollow  triangle  to  show  you  that  it is selected.  You can select
several lines  in  a  window  by  dragging  over  other  dots,  or  by
Shift-clicking or command-clicking.  Double-clicking on a sequence dot
or triangle opens a Sequence window; double-clicking on a track dot or
triangle opens a Graphic window (or a List window if the track doesn't
have notes).  The icons at the upper left may be used to open windows,
or to activate them - read their help for more information.


11.1  Control Bar

The Play button plays the sequence that  the  Record  button  records:
the  sequence's  letter  is  shown  in  the Record button.  If you are
editing a track from another sequence, use the Play Selection  command
(command-spacebar), NOT the Play button in the Control Bar (which will
play the record sequence, not the one you're editing).

The MIDI  channel  used  for  Thru  and  recording  is  shown  in  the
upper-right  corner,  next to the word KBD.  You can easily select any
of the first ten MIDI channels by typing command-1 through  command-0.
If  you  name your synthesizers in the Instruments window, their names
will be shown here.

The Map check box MUST be checked if you are using the Input Map,  the
MIDIKeys,  or  controlling  the Faders remotely.  If you are recording
several channels on one pass, use "Make from Instruments" in the Input
Map's  Mogrify  menu so that each channel will be recorded separately.
If you aren't recording several channels at once, use "Clear  All"  in
the  Input Map's Mogrify menu so that everything is channelized to the
instrument selected for KBD.


11.2  Sequence Window

To set the tempo of a sequence,  click  in  the  small  tempo  in  its
Sequence  Window,  NOT  in the large tempo in the Control Bar.  If you
change the tempo in the Control Bar, the sequence won't  remember  the
change.

Vision overview                                                 Page 8


To loop a track, click directly on the double-bars around the  track's
number  of  bars.  Repeat dots will show up, indicating that the track
is looped.  The sequence length is set next to  the  meter  and  tempo
tracks; if you have a 12-bar looping track, and the sequence length is
48 and is not looped, the track will loop four  times,  and  then  the
sequence will stop.

To edit part of a track, you must open an editing window; whenever the
sequence window is active, you can only operate on entire tracks.


11.3  Graphic Window

Read the help for the telescope icon carefully to  find  out  how  the
Option key makes zooming in and out very easy.

In a Graphic window, you can move notes just by  dragging  them.   The
cursor  will  change  to show you how they will move:  clicking in the
left part of a note will move it left and right, in time; clicking  in
the  middle  will move it up and down in pitch.  Clicking in the right
part will change  the  duration.   If  you  select  several  notes  by
selecting  a rectangle, or shift-clicking, moving any one of them will
move all of them; holding down the Option key  will  make  a  copy  of
them.

Clicking on the words Strip Chart at the bottom of the Graphic  window
lets  you  see  velocity,  duration, controller events, tempo, program
changes, text, etc.  You can change these  things  simply  by  drawing
lines:   clicking on the word Set at the left controls the effect that
the lines have.  Program changes and  text-type  events  may  only  be
displayed in the strip chart:  you must enter them in a List window.

If you are going to move sections of a track around, use the I-Beam to
select  the  parts  of  the track that you would like to copy, and the
place you'd like to paste.  You may want to  quantize  the  cursor  so
that  the selections occur exactly on bars or beats.  To copy from the
middle of a track to the beginning of a new track, be sure to open  an
editing  window for the new track, and select the beginning before you
paste.


11.4  List Window

Set the Start Edit point, in the upper left corner of a  List  window,
before inserting an event using the Insert Event icon.


11.5  Miscellaneous

The Panic button, which is located in the Faders window,  is  used  to
turn  off  stuck  notes.   You  can also type exclamation point (!) in
order to panic.  It takes a long time, particularly if you  are  using
both the Modem and Printer ports.  Watch the lights on your interface,
if any, to monitor its progress.

    That item on scaling time and inserting tempos at the same time caught
    my eye.  It works like this:  You select some range of events and
    invoke "Scale time".  In the dialog box you get to say, essentially,
    "Make these events fit into M measures plus B beats plus T ticks
    assuming a time signature of X/Y".  Then you check the box that
    says "Insert tempo changes to preserve timing".
    
    Presto you will have changed the events to fall properly on bar lines
    (assuming uniform tempo over the range) but on playback the timing
    will be the same.
    
    MTP does not have this.  Neither does PRO4, according to their tech
    support.  (PRO4 is just shipping by the way.)  I can't tell about
    Performer v3 from the brochure.  It has "scale time", but doesn't say
    any more about it.

    
    Well, for whatever its worth.
    I got Vision up and running on my Mac 2cx.
    I estimated it will take me at least a month of free time to
    really get into it and understand it enough to do quality work.
    
    First impression, excellent.
    The documentation is good, the program flows with you,
    and its really cool to see all your music tracks running
    at once, and be able to click to each part and tweak it.
    (this is my first software package for midi, so I'm naiive)
    
    If anyone has anything they'd like me to look up or whatever
    let me know.

    What kind of copy protection does it have?
    
    What is in version 1.1?

What requirements does it have hardware wise?

Thanks

Chad

    re: .3, and .4
    
    I notice .2 was Sept, and y'all wrote lately, so I thought I'd respond
    to prevent blockages.... I'd recommend calling a MAC/Music store
    
    My take is no copy protect, and requires a MAC+, 1 Mb RAM or better.
    This is from memory a while back, so probably faulty. Hence the
    suggestion to call a store.... Computers&Music (415)994-2909, or
    ComputerWare (800)326-0092, or something more local (I don't have them
    all in my little black book!!)  :-)
    
    Bruce Evans 

I just talked to a guy at Opcode and he said 1 meg (could be 1024ke) and
floppy 800k were minimum.  HD and more memory greatly recommended.

Chad

    Vision requires a Mac Plus w/ 1mb. A hard drive is recommended.
    I'm using it on Mac SE/30 w/ 1mb and haven't had any problems.
    
    Vision is copy protected and uses a install/deinstall procedure to move 
    it from one disk to another. 
    
    All in all it is a very slick program. The only nit I have is you can't
    import names from other Opcode editor/librarians. They force you to buy
    their universal librarian Galaxy.
    

Vision doesn't require a Mac+ according to the Opcode tech I spoke to yesterday.
Only a Mac with 1 meg (so a 1024Ke would work too).

Chad

    As long as it has the 128K ROMs and enough memory.  For example, if you
    took a 512 (not 512e) and added more memory, that wouldn't be enough.
    You need the new ROMs.
    
    Anyway, if you don't have a hard disk it won't fit on a 400K floppy.
    I have v1.1, and the application and its Preferences file almost
    completely fill 800K.  So I run with a stripped system in a RamDisk,
    and the music stored on the other floppy.  (in 2 megs)
    
    I'll second the "slick".  It is the best thought-out program I have
    ever used, for any purpose, on any machine.  (closely followed by
    "Managing Your Money")  DEC could learn a lot from studying it.

	I have Vision 1.1 on a mac 2cx and 4Mb.  I would not run it
	on anything less that 1Mb, and even on a cx with lots of
	screens going it does get a little pokey occassionally.

	It is very stable and feature laden. I really haven't found
	anything I dont have a need for. Its taken months
	to fully use it.

	I highly recommend it.

EZ Vision, subset of Vision was released few months ago. Has anybody tried it?
As concerns cost and performance, EZ Vision's rival must be Beyond.
Which is prefer ? Especially when using sound generator without keyboard.

sugimoto 

    A warning about Beyond.  I have not used it besides a brief look at the
    demo, but it is a non-mainstream product for its publisher, and was
    purchased from a third party.  I wouldn't make a big commitment to it
    without knowing whether it will be supported and upgraded.
    
    It is quite possible that it is less restricted than EZ Vision--Beyond
    is supposed to be a full-featured sequencer.
    
    	Eirikur
    

    One thing to keep in mind is that EZ Vision is not copy protected.
    
    Anybody know if beyond is?  And I was under the impression from
    speaking to a DR Ts rep one night that beyond was going to be a big
    thing for them...???

    Is there a way in Step Record to enter a rest?  I thought there was,
    but I have not been able to find it, and it drives me nuts.
    
    I have been hitting the highest key on the keyboard in place of a rest,
    then going back later and deleting all notes on that pitch.

	Yes, but I don't remember how.  It was on the keyboard
	itself (Mac keyboard).  It has been awhile since I used
	my Mac for Midi (or did anything Midiwise while I was at 
	school).  try the spacebar.  I think I hooked up a
	MIDI-event thing (you know what I mean) to trigger this.
	It has been a year or more since I did this.  With the
	version last year (1.1 I think), step entering got the Mac
	confused if you didn't slowly hit each key with a pause
	in between.  Does it work better now?

	Good luck! and report what you find

    Spacebar is the PLAY button.  I would guess hitting that would take it
    out of STEP-RECORD and start playing from the beginning.  And opt-space
    is "Play the selected notes".
    
    I usually do not enter notes fast enough to confuse it, as it seems I
    have to change the duration about every note or two.  I use the numeric
    keys for that.

There is a key for it though.  I don't remember Vision at all.
Try TAB and keypad keys, like KP0.

I had it set up like Master Tracks Pro usingthe Midikeys feature so that
one octave of the keyboard controlled duration and rests and the rest was
just input of notes.  That way I could step enter without having to
leave the music keyboard.  You can get going quite fast.

    Just my luck it will be KP0.  I have the old keyboard.  But if so
    I'll set up a MIDIkey for it.  At least I will not have to go back and
    edit out all the C5's.
    
    It isn't TAB;  that puts it into regular RECORD.

    
    I have Studio Vision...and just verified it myself...you could rest
    with the 'Play' from the main window (Studio Vision 1.31 on my MAC
    IIci)...or the spacebar.
