Quantity: 2 with my own DIY modifications and 2 with DB-800 modifications
From the Synthtech website:
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.
Added gate comparator with Schmitt function
Output limited to 5V max with clipping circuit
Output level LED
Here is what my DIY perfboard modifications look like:
The DB-800 version before final assembly:
The DB-800 after final assembly. I soldered all the wires, rather than use connectors.
