    One of two things has to be able to happen...
    
    The 707 send out a MIDI note number associated with each sound. Let's
    say the bass drum is MIDI note #28. The problem arises if the D110
    has a bass drum on MIDI note "something not #28". You've got to get
    the bass drum(s) on the same note number.
    
    Check the D110 manual (or send it over to your friendly local MIDI
    wizard) to see if the note numbers can be changed for the drum kits.
    
    ...or with ANY luck, the 707 can have it's note numbers changed.
    
    /e

    Yes, absolutely you can do what you want (and he says that without even
    having touched a 707 before...).
    
    First of all, there are fairly standard "Roland drum" note assignments
    for all Roland gear, and I can't imagine that the 707 is any different
    (I have a D-110 myself, and I know it follows them). Even if that were
    not the case, the instrument/note assignments on the D-110 are
    programmable, as is the MIDI channel for the rhythm part. Here's what
    you need to do:
    
    1. Figure out what MIDI channel the 707 is going to transmit on. This
    is probably settable, there may be some power-up default. Let's say
    it's channel 10 (a popular one for Roland drums). Go to the D-110 and
    make sure that the rhythm part (R) is set to accept input on channel
    10. You should immediately start getting some kind of rhythm noises out
    of the D-110 when you play the 707.
    
    2. If the instruments are not assigned to the proper notes, I'm sure
    that can be changed on the D-110. I've never done it on the D-110
    myself, but I've done it on the D-10, which is almost the same, and if
    you can't figure it out I'll check it out and let you know.
    
    Alternatively, it may be possible on the 707 to change the MIDI note
    output by a particular pad (I would assume it is).
    
    3. If (1) fails, you may want to check to cables (OUT/IN, etc), and
    also check the system clocks. I assume one will have to generate the
    master clock (presumably the 707), and the other be a slave. This can
    be set on the D-110.
    
    If (1), (2) and (3) fail, wait until they put the Roland manuals on a
    CD-ROM and run them through a pidgin-English translator, then grep on
    "bass drum" :-)

re:1-2...  Thanks boyths!

		I knew that just about dern near anything was possible...

	one thing I didn't consider was the R part....  Hmmmmm,,, 
	o.k..  To be honest, I didn't have as much time with the whole
	project first time I tried... so next time, I'll take a while
	and play... and play.. and play....


	next dumb question,, I assumed that the cable interface would
	be midi-out->midi-in, and subsequently, midi-in->midi-out..
	for the two units.

	Like two cables dude?

    Actually just 707 OUT to D110 IN will do just nicely...

    If I recall correctly the way the -707 works, what you want to do is
    possible in the following sense - you can have the TR-707 send its
    *programmed* data to the D-110.  I don't believe the -707 sends
    MIDI data when the keypads are struck, only when it's in pattern play
    or track play mode; but I may be wrong, I never tried this, and I only
    recall seeing the fact that you could use the -707 as a sequencer;
    I don't recall seeing the suggestion you could use it as a "keyboard".
    
    I know it is possible to reassign the note numbers to which the -707
    responds.  I think you can also change the note numbers it emits
    for its various drum sounds.  If you can't, as Ram has noted you should
    be able to fix this at the D-110 end.

	I do something similar. I have an MT-32 and a U-110 (and occasionally
	tie in a D-110) being driven from either a TR505 (the little brother
	of the TR707) or a sequencer.

	The connection is quite simple:

  	  +-------+                     +-----------+
          | TR505 |                     | SEQUENCER |	Controllers

         MIDI |                          MIDI |
          OUT |                           OUT |
              |                               |
              +------>--+        +--<---------+
                        |        |

                     +--+--------+--+

                            | MIDI IN
		+-----------+-----------------------+

		+-----------------------------------+


	The default note #'s will line up as long as every body is
	recieving on the same channel (In my case, the default
	for Roland is MIDI Channel #10 & That's where I left it).

	Since I doubt that you want to only use the D-110 for drums,
	you will require some sort of MIDI merger (The Anatek Pocket
	Merge - around $80.00 - works well for this) so that your
	TR707 can control the drum sounds while either a sequencer or
	other MIDI controller can play other MIDI channels (I have a
	total of 4 controllers, while the diagram only shows 2).

	Why would I do this if I'm using a sequencer?? Because I don't
	always use the sequencer; I like to be able to play anything that
	I want. This configuration allows for that.

	You'll have to live with the limitations of the pattern sequencer
	in the TR707, but that's not as bad as it might seem. I put a
	note in here a while back about drum sequences. If you can't find
	it, let me know & I'll Email you a copy.

      Hey Ray. Here's what I would do...
    
      Dump the 707, and pickup a used sequencer.
    Sequence your own drum patterns (drums on the fretboard are fun),
    lay a synthbass track over it, and play midiguitar over the whole
    thang.
      Now you be in midiland, mon.
    
    

Thanks for all the help guys,,, it's great to know there's such
a vast amount of technical advice available for free...

In our situation, we have to keep our main objective in front
of us...

the purpose/applications are primarily multi track recording.

All we really want to do is

A: (Primary) Use the Drum sounds on the D110, INSTEAD of the Drum
sounds on the 707 *WHEN* needed/desired.

B: Since the major application *IS* multi-track recording, a sequnecer
is not a necessity. however, there is a Sequencer in our future,, but
of course, not at this time...

At anyrate, a sequencer was not a primary necessity, where the drum
machine ofcourse, is..  The 707 had the right price, AND I've got the
D110,, the mission is how can I make the two work together, getting
the best of both pieces.  

So, given some play time (Tonight) we may work on this...  At this time
it's not a critical issue..  We're still so new to the drum programming
thing that we're not at this time too concerned with the networks
capabilities.  However, I do want to understand this because the drum
sounds on the d110 are more, and somewhat better than what's available
on the 707....   At this time, we're still learning how to use the 707,
and not overly concerned with it's 'voices' but I know that within a few more
weeks, we'll want our 'expansion' capabilities...

Anyway, MIDI is the coolest thing since walk in freezers...

Why-oh-why did I wait two+ years to jump on the band wagon?? Dam purists
anyway.

    
    
      From what I remember about TR707's, it's pretty easy to change
    the midi note # assignments for each pad. Just remember to make
    the 707's transmit channel ten *for each pad*.

    The -707 transmits and receives on one and only one channel at a time.
    There is no ability to define channel per pad or voice.

      Gee Len.. I seem to remember my old tr505 was capable of transmitting
    each pad on a different channel. I *assumed* the tr707 would
    have this capability. 
       I humbly beg forgivedness.
