Noise in KORG Volca Keys Delay Circuit


Audio Cookbook has a post up on the KORG Volca Keys Delay Circuit and noticeable noise introduced by the circuit. You'll find demos and additional details in the full post. Pic of the Volca Keys signal flow diagram below.

"To illustrate the noise introduced by the delay circuit I created a few versions of a simple test sequence. One without delay, one with the internal delay, one with Ableton’s Simple Delay, and finally one with my Electro-harmonix Memory Man Delay. The sequence sounds pretty clean on its own, but buzzy, high frequency aliasing becomes audible when the Volca’s delay is introduced. In comparison, Ableton’s Simple Delay doesn’t add any noticeable noise, while the Memory Man adds a little noise (and pleasant chorusing), but nowhere near as much as the Volca delay."
