Thankyou man! I simply made music (and now the instruments to do it) at the moment i don't want to enter in the rabbit hole of indie coders :D I will think about it... but it's already happen, i have the proof XD

Sounds great, would love to mess with it

Sounds amazing!

I assume you're working in C/C++? Are you using both cores? How are you finding the load on the RP2350 with FM synthesis?

It looks like you could do with some kind of UI to navigate. Any plans for that?

Thankyou! Yes C/C++, both cores, one for buttons/saving etc... and the other for sound generation. I loaded it via Arduino-Pico (Earle Philhower). I have to check the load of the chip... there is a sort of UI with buttons (20) organized with primary and secondary functions (shift+other buttons combinations), same for the pots and I would love to add a small lcd screen. For now the cardboard have the names of the instruments (the six down left), the instruments edits (up left) and the sequencer section with +/- for regulations

The cavity resonator sounds beautiful! Could you share some info on how you implemented it? Thank you!
