We cowl so many tasks right here at Hackaday that lead the creator down a rabbit gap of technological investigation that distracts us from the duty of bringing them to you. Such a mission is polyUAnalog, a really trendy tackle an analogue synthesizer. In case you are imagining a synth of previous with modules and patch cables, suppose once more. The trendy means to do that is it appears to make use of a person synthesizer chip for every voice, leading to a really versatile instrument certainly.
The built-in circuit in query is the AS3397, which when coupled on a PCB with a Raspberry Pi Pico makes for a self-contained single-voice analog synth. It’s managed through I2C from a conductor board for which frustratingly the README doesn’t give a processor, however we predict could also be powered by one other Pi Pico. This board does the job of taking MIDI and different controls, and farming them out tot he particular person voices. The prototype has ten, however it will possibly assist many extra.
It’s the work of a pair of researchers from the College of Angers in France, and we’re instructed it’s a facet mission from their work within the discipline of spectroscopy. There’s a video about it which we’ve positioned under the break, they usually’ve additionally written a paper about it.
