Something people forget is how much was done with so little compute power in the early days of the digital synth and how powerful modern microprocessors have become today. Rough order of performance from top to bottom.
[edit] 20240607 Thanks to all the comments and suggestions from r/synthdiy. Added Ksoloti Core rev 0.5/Axoloti Core rev 1.2 which are both 168MHz STM32's.
