I am in the process of completing the synthesizer part of my vocoder project. So far I have the faceplate, the mechanic, the VCA part and a few filters ready. Still a lot of work ahead. Stuffing all the filter PCB and trimming, doing the voiced/invoiced detection, input/output section, exciter part and housing. Here are some pictures.
Faceplate and the mechanical parts sawed and drilled.
Waiting for PCB.
Does the VCA PCB fit for the Vocoder fit?
Some Filters to the Vocoder added.
