Controllers and Editors for Synths, Keyboards and Effects

Eurorack version designed for Behringer 2-XM (Works with any MIDI equipped synth with 0-10V CV inputs)          Envelope - ADSR plots There are no Digital to Analogue   Converters -DACs  used in this design. The only additional components on the FVCs are op-amps to boost the 5v output to 10V. The ProMicro supports analogue output using PWM. If this happens at a very high frequency the output is very smooth. The output is filtered with a simple RC filter and there is no digital noise picked up by the synth. The Attack is 0-10s with Decay and Release up to 15s. The envelope is exponential. Here are some plots from various ADSR settings:           Basic Version - No CV Control  FVC-1         Four Voice Controller with Keyboard Logic and Faux Vibrato       All functions are controlled with CC numbers  so you need a controller keyboard     Polyphonic control of 4 MIDI chann...

Alternatively,  email me at  gmail - my name is chaz riff but without the space ;) Behringer 2-XM Polyphonic Controller This is the latest project - a four voice controller for the Behringer 2-XM. This is based on the Oberheim SEM which was the synth module that was in the famous FVS (Four Voice Synthesiser) from 1978. This project uses 2 Pro Micros connected via the TX and RX pins. I needed 2 because it requires 32 ins and outs.        FVC connected to 2-XMs More info  here Low Cost Polyphonic Keyboard Controller for mono synths A much simpler and cheaper alternative to the 2-XM controller. Very cheap to build and still has an on board polyphonic ADSR. All controls are handled with CCs f...
