BMC99. Dual Attack and Release Generator

picture of the module

This module is a 2-channel Attack/Release envelope generator. It uses “dividing” attacks meaning that while in the attack phase a new envelope cannot be triggered until attack has completed, allowing it to divide input pulses. Each channel can be set to a slow mode for very long envelopes and has inputs that ignore input gate length or wait to release until the gate is depressed.

Compatable in +/-12V or +/-15V systems, though 15V systems require some resistor value changes. Low Parts Count. PC Mounted pots, and mounting holes. Eurorack and MOTM connecter pads for maximum build flexibility.

Boards are available now. Price for 1 PCB is $8.
Unfinished eurorack panels are available for this project, they are 8HP and cost $8 each. There is more information here about panels. If you're interested in drilling your own panel for this project, feel free to use my drill guide. That image should be printed at 300dpi for proper scaling.
