BMC83 Voltage controlled delay

picture of the module

This module provides an audio delay line with voltage controlled delay time and an audio feedback path, making it useful for echos, reverbs and general experimentation. Delay time ranges from 60ms to 4s, though audio fidelity drops significantly at longer delay times.

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


DEMO 1. Demonstrating minimum to maximum delay with no repeats

DEMO 2. Demonstrating minimum to maximum delay time with feedback (repeats)

DEMO 3. Low Pass filter placed in feedback path with it's cutoff modulated by an LFO.

DEMO 4. Frequency divider placed in feedback path of delays creating octave drops.

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.
