solid

Zomba, 10.01.2019
Very useful module. Only dropped one star as it is unnecessary wide, as it is often the case with Doepfer modules.

Mmm... Shepard's Tone

Simon P, 29.07.2013
I specifically bought this module to help me create a shepards tone. You know, a forever rising or descending tone.

Well this works great.

I've also been using it a lot in conjunction with four sound sources and four VCA's to create slowly morphing soundscapes.

It can also be used as a pretty sweet sinewave oscillator when used at audio rate.
