I just had fun making this Colab notebook which explains how to build a sound synthesizer from scratch in Python. You can play with it now at:
colab.research.google.com/github/agero...

It covers sound generation, melodies, sound effects like echo, panning, low-pass filter, etc.

Enjoy! 😄🎹🎶

I wrote a free online appendix on State-Space Models (SSMs) for my new book, including LMU, HiPPO, S4, and Mamba:

I hope you'll find it useful! 😊
