cmu-800r “If you’re looking at this I’m sure you know what it is, it is in excellent condition other than the blemish on the front that I did to it. I do not have the card for the Apple computer that went with this but as you may know there are retrofit kits available for this that make it accessible via MIDI.” Link

CMU-800, Roland @ 03 July 2016, Comments Off on Roland CMU-800R

cmu800r “Up for auction is a very rare Roland CMU-800. It is a multi-timbral analog synthesizer with 2 mono synthesizer channels (one for melody, one for bass, although they can be used for anything really), 1 polyphonic synthesizer (4 voices), a 606-like drum channel, and two channels dedicated to cv/gate out (although all 8 channels can have cv/gate out). The unit is connected to a MIDI-IF box which allows you to unlock all of the CMU’s functions via MIDI (Melody on channel 1, Bass on 2, 3-6 each of the poly voices, 7 and 8 separate dedicated CV/gate, 9 poly chain mode of channels 3-6, and 10 for the drums). There are many MIDI CCs per voice that the unit responds to, like LFO speed/depth/shape. As you can see on the back, there are 8 channels of CV/gate out so each of those MIDI channels sends cv/gate as well. This makes it a very powerful synth as well as MIDI-to-CV/Gate converter. The ports on the MIDI IF box are MIDI in and a DIN SYNC out, which allows you to sync another DIN device to incoming MIDI clock. It includes the power cables, MIDI box, connector cable and synth itself.” Link

cmu8000r “rom a collector’s estate, this is a Roland CMU-800R synthesizer unused and unwrapped in its original box. I am not able to test it as I don’t have the correct computer, but It has been stored unopened for years. It appears to be in excellent condition, but is being sold as is. The box will be wrapped in brown paper for shipping – if you want it sent inside another box, shipping will be a little bit more, just let me know. Please examine my photos as they are an important part of the description” Link

cmu 800r “Not sure what this does but if your looking I’m sure you do. In really great condition, one mark on front panel (could be removed possibly). Fires up fine (light up). Looks like it has barely been used, given to me years and years ago by an old friend who was super into keyboards. In original box (box is not in great condition), original manual and warranty card. If you are into vintage synths and are looking for this item you will probably not find one as clean. Happy bidding!” Link

The Roland Compu Music CMU-800 is a four-channel mixer with internal preset voices and sequencer software for an Apple II or PC, built in 1983. There is a ribbon cable out the back. It features analog synthesis with fixed sounds. Four note polyphony in the chord section, monophonic bass and melody synth sections, and an analog drum section.The Chord/Melody section has only 1 sound. The drum section is similar to the TR-606 Drumatix, and the bass section is similar to the TB-303 Bassline (some limited adjustments in sound were possible via software). It has separate melody, bass, chord, rhythm, mix outputs. There’s also 8 cv/gate outs to run external analog equipment by control voltages, and there’s a click in/out. On the face it has knobs for portamento, Melody sustain & decay, Bass decay, and Chord decay. It also has volume level sliders for each of the instruments and a master volume slider. The software uses a similar music programming method as the MC-8 or MC-4. This is a brand new unit only opened the box to make sure they power on. We have no other way to test beyond making sure the power works. You can use this unit with either a commodore or apple 2 I am also told that a MIDI retrofit kit is available for this unit that turns it into a full CV gate interface and also provides access to the sounds.” Link

NOTE: This auction is one of two of these units I am selling. I already sold the first one. It went very fast. I expect the same to happen with this unit. I will NOT be listing another one and it will likely be a while before you get the chance to buy another, just based on how infrequently they are listed.

NOTE PT. 2: Thanks to user HouseOfSerekh for pointing out that an A2 card in not absolutely required and that a MIDI retrofit kit is available for this unit that turns it into a full CV gate interface and also provides access to the sounds.

NOTE PT. C: It does not come with the interface card or any software (see: NOTE PT. 2), what you see is what you get.” Link

“What you get. Roland CMU-800. Apple IIe computer(Has had power supply rebuilt) and Apple IIe Owners Manual. Video Monitor.MPC Electronics Sync track so you can control the CMU from your din sync equipment(timing sounds better to me doing it this way around than syncing from the CMU, but you can do it that way if you want, with some experimentation)

This is a fairly unique opportunity to get hold of a Roland CMU-800, and the computer required to run it, with an easy to use and space saving SD card floppy disk system, without having to spend months/years trying to put your own set-up together. Buy it all in one go and take all the ball ache out of the equation. Hook it up to your CV/Gate synths and start making music now.

Mint condition and working Roland CMU-800 8 channel CV/Gate Sequencer and manual,with built in 7 voice analogue drum machine supposedly similar to the TR-606.(I actually prefer the CMU’s drums as they seem cleaner and snappier to me than the 606.The hats are also better in my opinion.” Link

CMU-800, Roland @ 24 February 2013, Comments Off on Roland CMU-800 Project Machine

“This auction is for a Roland CMU 800 computer module sequencer/drum machine in pieces for parts or a project. I borrowed a fuse from my other project CMU and the unit powers up. It could possibly be pieced back together and used for its intended purpose provided you could find the correct ribbon connector, interface card, and software. I make no guarantees as to its functionality though. My recommended use for this unit is to use as an analog drum module. I have successfully triggered the great analog drum sounds these units have off the lower board. They are reminiscent of Roland TR 606 and Boss DR 110 sounds. Also, the power supply could be useful for you modular guys as it outputs 15v bipolar and 5v. It is missing the ribbon connector for the interface card, the screws that hold the lower board to the upper board, the screws that hold the body together, the power supply fuse, and the connector that connects the power supply to the lower board. I will include an additional connector cable that connects the power from the lower board to the upper board. It is too short in its present state to connect the power supply to the lower board when assembled correctly, but could be extended. Cosmetically, it is beat up pretty badly. There are spots of rust, remnants of stickers, marker, and the US Navy property metal sticker. That’s right, this is military surplus. This unit is obviously sold as-is.” Link

“This is a mint condition roland cmu 800.

This is supposed contain the guts of a roland tr 606 analogue drum machine as well as a close cousin of the famous tab 303, some sort of poly synth and four channels of cv gate for external gear.

It comes in its original box and packaging and is essentially a new item . Think museum quality piece.

I honestly think this item has never been used. Selling it as I was never able to locate an apple 2 or commodore c64 to use it. Looks like there are plenty of mods discussed about it on the net.” Link

“This is a quality built vintage piece that we know nothing about except that it is supposedly a very early analog synth (or control surface??) that integrates with Apple or Commodore Computers. Cosmetically, it has a few scrapes, but still looks good. Electronically… at the least, it NEEDS A REPAIR TO THE RIBBON CABLE, (has possible punctures, tears and / or abrasions), so unless you can solder and rig some jumpers into the bad spots, this may not be the one you should bid on. Great parts though! A quality case, knobs and faders, if nothing else.

Appears to be new, but it is untested with visible scrapes and ribbon cable problems… no supporting docs or software, except for this link to a manual we found online” Auction ended. Click here to browse on eBay.
