Percussion Sensors

PAiA article - Percussions Sensors - Converting oscillatory signals

The signals produced by most percussion sensors will require some processing before they’re useful as triggers.  Usually this means converting an oscillatory signal into a single unambiguous pulse that is appropriately scaled to carry the widest possible range of velocity information to the circuit being controlled.  The circuitry in the diagram below performs this function.…

MIDI2CV8 to Drum Tone Board Connections

PAiA Drum Tone Board Connections - Diagram

Power for the Drum Tone Board can be tapped from the MIDI2CV8 aux. power connections using the parts shown to the left.  The nominal “+5” bias line of the Tone Board will be more like 7 or 8 Volts using the values shown and the Tone Board will like this fine (better than 5V, actually).…

Drum Tone Oscillators

PAiA Analog Synthesizer Drum Tone Oscillators

The circuit shown is the most interesting of several drum oscillators on an analog sound board that appeared as part of an article in the June 1993 issue of Electronics Now. Like most drum tone oscillators, the circuit is a very high Q resonant filter that is only slightly overdamped and on the verge of…
