Mario Becker - mb'knobs

Custom Synth Voice based on Doepfer DIY synth

A while ago I started building my own Eurorack synth with some self-made modules. This one is a PCB to hold all the knobs and stuff required for a Doepfer DIY Synth module. So I call it "mb'knobs".

This module requires a Doepfer-DIY-synth-module to run (not included) !!!

The PCB will be stacked onto the DIY-Synth and is hold in the front panel by the screwed potentiometers. The connectors for the patch field are on smaller separate PCBs which are also screwed on the front panel, they could also be moved to the left or right side to have the cables out of the way.

Features:

• Circuit similar to example in Doepfers Docu
• Noise generator on board
• Overdrive OpAmp on VCF and VCA inputs.
• Small Proto area and materials to build a dual suboctave generator. (Flipflop frequency divider, creates rectangular wave 1 and 2 octaves below synth signal, thickens up the sound)
