1195.1 | no way, jose | JON::ROSS | we is wockin'.... | Tue Feb 09 1988 10:30 | 17 |

could be lotsa things....you have NO cords in midi?
WHEN does this 'jump'? Youre playing? youre staring
at the unit? when? AND to what? just up a patch? random?
Cords wraping in midi is a band aid. You have some
sort of defect IF you can prove you arent sending
it program change messages.
Mines been fine for 2 months or so....
Id put my money on the connection to the front panel,
and/or the switch itself. Could also be noise, or a
semi-bogus supply pack.....

| I have had no such problems with mine. Then again, I use the MIDI
on it all the time.

Re. .1 I have no cords hooked into midi at all. Since I am not
using Midi, I have nothing assigned to any of the midi patch
locations, except that I have the unit set up to go to program
00 when it powers up.
When I originally started having problems I was using program
91 (love that multi tapped pan effect) and with a fairly steady
signal going to the Midiverb (the green led on steadily but not
the red overdrive indicator) the unit would jump to several other
program numbers like 91-80-55-18-00 (randomly) then stop, I doubt
if there was any repeatability to how it was jumping, and to my
knowledge these programs were not assigned to midi patch locations.
The guy at the store (Ted Herbert's Music Mart) said he would bet
that it was a bad EPROM.
Lately, I have been experimenting with this new GK preamp I just
bought. I have been turning on everthing in the rack, but not really
using the MidiVerb, just staring at it so to speak, and have noticed
a few times that it will try to jump from program 00 (defeat) to
where a single 5 will flash for a second and then the unit returns
to 00. Maybe my eyes are playing tricks on me. Either that or maybe
the unit is haunted. Maybe it's a conpiracy!!!
I am not sure if I have a real problem yet, but I just thought that
strapping the input and output together might help to keep it stable
especially if it is getting bogus patch signals out of the air. I
would rather spend $5.oo for a midi cord than to send this baby
back for repairs again.

Duh, I hesitate to venture a guess, BUTT !
You say that you have nothing hooked up to its midi connections,
so I was just kinda wonderin' if that could be your problem, i.e.
an open input lookin' just like an antenna.
Reg {Not that I know what's expected to happen with MIDI
open inputs, I don't need to cos I won't buy it if I'm not gonna
hook it up real soon}

1195.5 | Mine goes "Phhtt" every once in a while... | JAWS::COTE | Behind the keyhole, with my fisheye | Tue Feb 09 1988 14:14 | 13 |
| It seems to me that strapping your OUT to your IN would be likely
to *increase* any weirdisms.
As the unit sits now, if you have any noise that could be mistaken
for MIDI data appearing at the OUT port, it simply goes out the
OUT port and falls on the floor where the cat will kill it. But,
if you were to route this back to the IN port, the machine would
respond to it.
Right now, it seems that your problem is all internal. Adding the
cable would give the bogus datums a second route to travel.

| Theoretically, the opto-isolator shouldn't be able to light without
juice going to it. (Have you ever seen an LED just light up with
nothing hooked to it?) Not that it couldn't happen. In fact, I
could probably get an LED to light given a dry room and a little
shuffling. My guess is that if it ain't the PROM it's noisy power.
Could be a bad power pack. Could be a noisy AC line. Could be
dirty/shorting buttons as has been previously mentioned. Could
be any number of bad parts in the internals. Going for the easy
stuff, I'd try a new power pack or try plugging in the unit somewhere
else and see if the problem can be duplicated.

1195.7 | It's Cellular MIDI RFI From the Soviet Embassy! | DRUMS::FEHSKENS | | Tue Feb 09 1988 15:13 | 13 |
| re several previous replies:
Hasn't anybody got the nerve to tell him point blank it's broken?
A "floating" MIDI input's not the problem. Otherwise synths would
start playing by themselves.
I doubt you've got a bad PROM (E, senior or otherwise). It's some
kind of intermittent, I'd guess. Does it seem to be sensitive to
vibration?

1195.8 | Don't gimme no static.... | OILCAN::DIORIO | | Tue Feb 09 1988 16:21 | 7 |
| Static electricity has been known to do strange things to electronic
gear. Mark, are you using the unit in a room with a rug in it? Being
winter and all I wouldn't rule it out. Static charges in the kV
range are not uncommon.

1195.9 | what *are* the odds? | JON::ROSS | we is wockin'.... | Tue Feb 09 1988 16:53 | 16 |
| The power supply.
The switch.
The connection to it.
Some other problem but NOT pulling flashes of light out
of thin air that happen to flash on and off at 31Kbaud
with 2 bytes (or is it 3?) of 10 bit patterns (1 start
bit one stop bit) and the first byte of which is 0C0 hex.
You should be so lucky at megabucks.
MAYBE fetching instructions from Rom, but probably not,
because the unit would (statisticaly) do other odd things
too.
STEP ONE: Try another supply!

| Also try another MIDIverb. Borrow one from somebody and install it in
place of yours, in the same rack if it is in a rack, same power supply,
etc.
If it works, then yours is BROKEN. Make them REPLACE (not fix) it.
(assuming it is under warranty and you sent in the card...)
If it fails the same way yours does, the problem is in your room.
Could be the power supply, could be something else. (Later take
the borrowed machine back where it belongs and make sure it still
works after being in your possibly damaging environment (unlikely
to break something, but possible).

1195.11 | MV-II, I love it | SQM::VINSEL | she took my bowling ball too | Wed Feb 10 1988 09:06 | 19 |
| I know that this isn't a general MV-II note, but it's the most recent
MV-II related note.
I finally got a chance last night to play with my MV-II. I decided
to go back and remix some tapes of live music. I recorded everything
dry (4 tracks: live mike, PA mix, Guitar, Bass) and had in the past
just used a cheapo digital delay stomp box during the final mix.
I know what you're thinking... but I always try to make do with
the equipment I have. Well I guess I don't have to tell you but
the MV-II made an absolutely incredible difference. One of the problems
that I've always had making live recordings is that it is nearly
impossible to get a mix that can capture the 'live' feeling. I think
the MV-II has let me do that with great ease. Now I just wish I
could get the free time to remix all of my tape collection. But
now that I think of it, maybe I should spend more time making new
recording...

Move on to new material. I've gone through that process myself when I
get a new piece of equipment--should I work on new material or should
I go back and redo some older stuff? After thinking about it a long
time, I've decided it's always best to move on and write new material.
Especially with the fact that most of us don't have a lot of spare
time to dedicate to music, I think it's important to keep moving
ahead and not over-analyze the past work you've done.
By the way, the discussion in this note has me thinking a midiverb may
be the next piece of equipment on my list...we always have to
be thinking ahead, right?

1195.13 | Ah second tha motion ... | ECADSR::SHERMAN | No, Rodney. That's *old* science! ... | Wed Feb 10 1988 13:14 | 11 |
| I agree with Peter. MOST of my stuff I feel like doing over. What
I tell myself is to wait until DAT comes along or until I have some
real reason for doing things over (like a recording contract? har,
har, har!). Anyway, ya has ta ask yourself why you're doing it.
For most, it's for the pleasure of expression, which is maximized
when you work on something new. Um, to keep in line with the topic,
I'm glad you got an MVII to play with. Nice beast. Hope the one
in repairs got fixed ... (note how *smoothly* I glided back onto
the topic?)
