Alpha

Dreadbox's 22 HP MIDI to paraphony converter followed by a dual envelope generator: two ADSR envelopes, each with a bipolar LEVEL, a slow / fast RATE and its own gate input, and a MIDI interface with two glided pitch CVs, gate and mod wheel.

Key features

• Envelopes A and B: attack, decay, sustain, release; LEVEL from -8 to +8 V (centre null); RATE 1 slow (A to 20 s, D and R to 25 s) or 2 fast; GATE in (a local gate cuts the MIDI one, 1 to 12 V), OUT
• MIDI INPUT (DIN): GATE out (0-5 V, its LED), MOD wheel (0-5 V), CV 1 and CV 2 (1V/oct, 0-5 V over five octaves) each with its GLIDE
• Paraphony: one key plays both CVs, two keys the low and the high note, three or more the low and the second lowest; unison, retrigger and MIDI channel (omni or 2 to 7) on DIP switches at the back
