Thank you for sharing =) My intention is to give just a basic playground which can be modified by your needs. I've commited one update 2 days ago regarding the USB MIDI implementation. The other update using the screen will appear in the sampler project first. I try to keep it modular so you you can put different parts together. |

The ADC module uses an analogue multipler to rotate through 8 knobs as an extension. This is only 8 of many parameters to control the basic synth. I'm just at the point now where I'm actually playing it.
I figured out whats going on enough to control parameters on a based ESP32 dev 1 board using a single POT wired between gnd/3.3v and 2 buttons for parameter switching. I might get it to dump parameters to screen so I can create a file of patches to save time.
Basically i created a bit of a noise filters so it doesn't make too many update calls. Only when you turn the 100k pot. Does a very slight oversample - nothing like Marcel's one in the adc_module.ino
I'm putting a bunch of physical button, pot handlers like this in the ADC as an alternative test harness until I get my midi control and start making some kind of map.
I think next I'll map one button to rotate through the wave forms. It takes time to get to know Marcel's code and I'm a rusty coder but I'm getting there.
Basically I'll have to fork the project but waiting until its updated before I do that. I never forked anyting on github ... so that will be a first for me. I don't really want to fork but ... i want people to be able to use this or document how it works for people learning. I'm just glad this exists and is shared at all.
