Forum member GoatBoy used the MSA-R to provide MIDI control for an array of solenoid-activated bells.  (Note: The MSA-T and MSA-P may be better choices for solenoid-based projects.)

Spunky Toofers used an Akai EWI 3000 to trigger a MIDISpeak and effects.

Firmware Updates

Firmware has been updated for the MIDISpeak, MIDI2600, MPA, SKM and UMR kits. The updates address an incompatibility with some MIDI controllers & sequencers which can cause an imperfect note response. The recent MSA firmware update also addresses this issue.

Products purchased after February 1, 2008 include the updated firmware. Microcontroller ICs from earlier products may be returned for a free upgrade. Please send email for additional information.
