225h

Buchla's 225h MIDI and CV Interface, a 200h series half module: a MIDI decoder with jack adaptors and CV converters, to play a Buchla system from MIDI and to join it to other modular formats.

Key features

• Eight MIDI outputs on bananas: pitch at 1.2 V/octave, note on, bend, mod wheel, aftertouch, velocity, volume and controller 4
• Three adaptors between banana, Tini-Jax, 3.5 mm and 1/4" sockets, the CV one with a diode against negative voltages and a gate-to-pulse converter
• A CV processor: -5 to +10 V scaled by 0 to 2x and offset by 0 to 5 V, out on a banana, its input and output on lamps
• Pitch converters from 1.2 V/octave to 1 V/octave and back
