Synthesis Technology MOTM-850 Pedal Interface

The MOTM-850 interfaces Roland, Yamaha and CV-out pedals to other MOTM modules. It provides 2 signals: a CV out that can be set with RANGE and OFFSET controls to cover -7.5V to +7.5V with varying 'sensitivity', and a GATE output. The GATE output can be internally jumpered to provide normal positive-going +12V output or Moog-compatible S-TRIG (shorting to ground) output. A panel LED indicates when GATE is active. A panel control sets the point at which the GATE becomes active. A useful feature is the MIX input and level control. You can add the pedal output voltage to whatever voltage is present on the MIX input. This allows, for example, adding the pedal CV to a keyboard CV to provide 'pedal portamento' effects.

Easy to build, the MOTM-850 can be jumpered for a wide variety of pedals that use 3-conductor plugs. The clever circuitry automatically adjusts for Roland/Yamaha differences. You can also feed a CV into the MOTM-850 PEDAL input without using a pedal at all! All of the controls are fully functional, so the 'pedal interface' can be use to generate GATE signals from a LFO, convert GATE to STRIG, and many other uses!
