Does anyone know of any good books on audio synthesizer circuit design.

I'm an EE major and i would like to build a synthesizer for my senior design project. The project should include timer 555(datasheet: https://www.apogeeweb.net/circuitry/ne555-vs-lm555-timer-ics-what-is-the-difference.html) I've built a basic setup using Radio Shack parts (555's, 741's, etc.) but I want to build something with more stability and style!

I own theory books including Sergio Francos excellent book on op-amp and IC design. But i would like to find a book which gives a more detailed design description of actual circuits used in audio synthesizers.

Tube based synthesizer design would be another cool way to go!

I just need more info.

Thanks,


Make: Analog Synthersizers (https://www.amazon.co.uk/Make-Analog-Synthesizers-Ray-Wilson/dp/1449345220) was a good read for me

Probably also worth asking in the Synth DIY Reddit, and DIY forum on ModWiggler too
