I wonder if it would be possible or interesting to also have a standalone 909 sequencer box without any analog voicing. Just midi and trigger outputs.
Good luck with the project!

Cool!

Do you intend to design an enclosure and bits to build up a whole unit? Or will this be aimed more for repair/restoration of existing units (which tend to sell for like $3000 or more :D )?

I second that emotion. A standalone sequencer box with just midi, trigger, and accent outputs would be ideal to work with arbitrary drum modules.
Licenced to solder since 1993

Im very interested in the notion of using the sequencer with the mb9090 clones. I have a working mb9090 that doesnt get enough use from lack of a sequencer :mrgreen:

If you need a good "drum machine without sounds", build yourself a MIDIBox.

I put 4 MIDI outs on mine, plus 8 triggers (you can have up to 64), as well as 8 voices of CV/Gate.

You'll have yourself a fabulous drum programmer using just one of the 16 tracks. It's very much like the TR-606 programmer in that you can write/edit/save patterns while the thing runs. Up to 256 steps in a track. Loads of "shuffle" options, even custom shuffle templates.

Then you can program more drums, basses, 303s, chord stabs, etc on the other tracks :-)
