DIY Synth log #2



Little board I made to help me in developping the programmable synth. Seeing how so many things need to be controlled by DACs (for preset recall and automation), made a little 16-channel multiplexer with sample-and-hold.

Still shopping around for a simple 16-bit DAC. most are either SMD, or are I2S (too slow) instead of SPI. And I can't spare the pins for parallel. Eugh...

Have you thought about doing an analog/digital hybrid?

Perhaps it would be easier to build an analog VCO, VCF, and VCA and have all the control (ADSR, S+H, LFO) be digital
