Delayed Modulation Module PCB

The MFOS Delayed Modulation Module is an attack/release envelope generator, Low Frequency Oscillator with square and sine waveforms, and a Voltage Controlled Amplifier. These separate elements are connected in the classic delayed modulation patch such that the LFO is fed to the input of the VCA and the AR generator is connected to the VCA's control input.

Introduction

If I had a nickle for every time I've patched up delayed modulation (also known as delayed vibrato) I would be a very rich man... well maybe I'd at least be able to get a coffee at Starbucks.

Anyway... this module includes an Attack Release envelope generator, Low Frequency Oscillator with square and sine waveforms, and a Voltage Controlled Amplifier. These separate elements are connected in the classic delayed modulation patch such that the LFO is fed to the input of the VCA and the AR generator is connected to the VCA's control input.

When you apply a gate to the circuit the AR generator is gated on and the VCA responds to the applied envelope and the LFO comes through the VCA. You use the output of the module to modulate other voltage controlled modules. Since there is a complete AR generator built into the module you have some nice flexibility. You can do the usual slow increase in modulation or you can do the opposite meaning use a fast attack and slow delay so that the modulation starts high and goes low. I built this module into my keyboard controller and I love it

Current drawn by this module is about 20 mA from +12V and 20 mA from -12V.
