Not an Issue, only a hint to another line projects like Yours #1
Description
Hi Otem,
I am watching Your DIY-Synths now for a long time. I have seen Your cool Woodwork. For me, it looks impressiv. You mostly use "simple" hardware and You make really art out of it. I know You prefer the Teensy - ICs. I had played around with Teensy and the ESP32 too but less luck.
Since this Year, a new developer has tried to create something with the ESP32 Wroom and the ESP32 A1S which includes a complete Audio-Interface. As the ESP32 has 2 Cores, one core could process Audio and the second manages the UI or the Sequencer. I believe, this could be a new option for You. Check Github and Youtube for "Marcel Licence ESP32".

He created a Basic Poly-Synth, a Sampler, a Looper ( Recorder), a FM-Synth and a Drum-Sample-Player. Most Projects are on Github! Only his Organ-Project is not on Github.
In some projects, he is able to use full 32 Bit for example for the Basic-Sampler which is better than the Teensy-Thing. The A1S is limited to 16 Bit in his code, Up to 32 Bit with a PCM1502. Perhaps these examples are interesting for You.
I stumbled across this project, pushed the code onto my old ESP32 and it works flawless. Currently I am trying/learning to use the second core of this ESP32 to create an UI ( Buttons, OLED; Pots, Rotary Encoder), Sound is comming from Marcels project.
Best Regards Erich
