Synthesis Technology MOTM-800 Envelope Generator ADSR

The MOTM-800 provides the standard ADSR (Attack, Decay, Sustain, and Release) envelope for controlling VCAs, filters, and other CV inputs. Both positive-going (0V to +5V) and negative-going (0V to -5V) envelopes are simultaneously available.

Attack, Decay, and Release times can be set from 1ms to over 14 seconds using the smooth feel, conductive-plastic Bourns log pots.

The MOTM-800 actually can be operated in one of 3 modes:

GATE & TRIGGER: a full ADSR (Attack-Decay-Sustain-Release) cycle, with re-triggerable AD portion with GATE on and a new TRIGGER. GATE only: A-D-S-R using Roland "drop GATE" synths (SH-101, etc). MOTM-800s generate full ADSR cycles with GATE only. TRIGGER only: A-D cycle, useful for "stretching" drum pad envelopes.
