WAV Trigger Interface

Here is the interface proto-board ready to rock. You can trigger the WAV-files with push-buttons or external CV-triggers. The transistor interface circuit is repeated sixteen times. The interface-board gets power from WAV Trigger's PSU.

Eurocircuits Naked Proto

I am testing a new PCB-service Eurocircuits. They have a Naked proto service which is a fast proof-of-concept board with no soldermask and no silkscreen. The price is 50% lower than fully finished PCBs. With no soldermask it should be easy to cut tracks or add wire links if necessary. This is a proto of my interface to WAV trigger.

EWI and Mutable Yarns

I wanted to put my Moog Prodigy clone to one portable case where is everything necessary to produce sound with my EWI-controller. So I ordered from Thomann a custom case with their 3D configurator application It holds one 6U-frame from Clicks & Clocks.
I ordered Mutables Yarns MIDI2CV module so that I can have that also in this portable case. Until this I have used my trusted Kenton Pro Solo MIDI2CV-box for this application.

Yarns have one assignable CV-out from where I can control Prodigys filter with how hard I blow from EWI. Yarns can convert this MIDI-controller information to voltage between 0-5V. That's not enough for Prodigy where I need double of that. So I built a CV Processor module where you can offset the CV and/or amplify it with maximum gain of 2.
