Have built a Thomas Henry LM-VCO and in the middle of building an Eddy Bergman / YuSynth ADSR and a VCA. Hooked up to an AI Synthesis Stereo Matrix Mixer and Hexinverter Mutant Brain with an Alesis QX-49 keyboard and SR-18 drum machine.
What should I do with the last 10hp of my case?
That sounds like a plan.
I have some leftover TL074, a few CA3080, a few LM13700, and plenty of TL072 and basic CMOS chips and opamps, but I dont think I have the CD40106, but isnt a Schmitt trigger something that can be built entirely from transistors?
I’m thinking of making a 12hp generative module using arduino, DACs, and some code to operate as many CV controls as I can manage. Would be really cool to have it be able to implement a physical model algorithm for a guitar pluck or something, too.
Oh for sure you can use transistors. Slightly Nasty makes a full fledged VCO from transistors. So a great micro controller would be either the teensy line or even a RP2040 (I think that’s the designation it’s a raspberry pi based microcontroller.). Look up the Europi they have some great code examples you could look at.
