Tim Laursen combined a power supply, drum machine, mixer, MSA-R MIDI decoder, Darlington drivers, and a collection of individually miked, solenoid-actuated drums. The result is “Double Rainbow”, a complete mobile robot drum system.
Some technical details can be found in this forum thread. Tim’s work also appears in this video from Sequence of Waves.
Several “makers” at the recent Maker Faire Detroit demonstrated projects that incorporate Highly Liquid MIDI decoders. For more photos, see the new Highly Liquid Photostream at Flickr.
Chip Flynn (Apetechnology) brought several robots, including an MSA-R controlled string instrument (background left):
Dana Dolfi demonstrated the MSA-T controlled Great American Horn Machine:
Dave Kadlitz performed with his MSA-R & MSA-T controlled mechanical drum machine, the “Waits-o-Matic 9000″:
Michael Una performed with an MD24-synced DIY sequencer:
Steve Averill‘s robot drummer first appeared in this blog as a pair of disembodied plywood forearms.
The “Spruce Deuce” has since become a sophisticated android drummer brought to life by 11 RC servos. Servo control signals are generated by a single MD24 MIDI Decoder:
Compare to Steve3PO, an MSA-T driven MIDI robot drummer.
Other MD24-based MIDI percussion projects are underway and are being discussed at the Highly Liquid Forums. Have you joined the forums yet?

Atari 2600 + MIDI2600 + Synthcart + Ableton Live + Modular Synth demo (SYNCHRO):
Bob Lloyd‘s animatronic Halloween program, which uses MSA-T MIDI decoders for MIDI lighting control:
A MIDI retrofit of the Synare Percussion Synth using the MSA-P (the simulacre):
A vintage Ace Tone Rhythm Ace drum machine, MIDI retrofitted by Kerry Bradley using a MIDI2600 kit (Note: the new MD24 is a better choice for this type of project):
The new MD24 MIDI decoder accepts MIDI input from a keyboard, sequencer, or other MIDI controller and in response generates up to 24 independent output signals.
Each output can provide either a general-purpose on/off trigger or a PWM servo control signal.
Features include:
The MD24 is available either as a kit or fully assembled. PDF documentation is available at the product page.
Michael Una documented the creation of MSA-R based MIDI-controlled robotic percussion instruments for an article in the new Make Volume 15. “Drumbot Activate!” begins on page 60.
