Raspberry pi sampler

#Devlog:1 i worked a lot on a app, i wanted to be able to load samples on the raspberry pi directly from pc through serial communication like you drop in the wav file and it uploads but i found out that it isnt possible, atleast not without complications, so i decided to ditch the app i worked 5 hours on and make the sampler and that code is a nightmare, i did use ai to understand whats even going on but i am getting the hang of it. The sampler will work through playing sounds with pygame and im having a really really difficult time recording the samples. So yeah thats about it
