ELECTRONIC MUSIC CIRCUITS:
"1982 ~ 302 pages

Scarce title. This fascinating book covers everything you need to know to design and troubleshoot analog synthesizers, including detailed information on SSM and Curtis (CEM) synthesizer chips. A definite must-have for the analog synth enthusiast, filled with schematics and technical information, as well as a few photos of Moog and E-mu Modular systems.

Is the most comprehensive book available dealing with analog circuitry for music synthesizers.
Discusses design of synthesizer elements so that the reader can begin to design his or her own system.
Details the custom ICs used in the majority of synthesizers
Describes construction methods
Gives secrets of many special-effect devices used by musicians.
Is written for studio engineers, musicians, computer and electronic music hobbyists
Contains a minimum of mathematics

I did some of your main mixer with the controls in order to answer yours.

I want to thank you for posting this. but I also want to share my honest opinion. a lot of improvement to these circuits has happened in 37 years. the silicon of a new curtis is not the same as the old curtis. the better methods for stability and linearity in these VCO circuits simply was not yet invented in 1982 but it has been fully understood in 2019. it would be best to read the book and then google the name of the chip for the new improved version of each VCO circuit before actually building it. a lot of this information is free on the web anyway.

all the matched transistor pair IC part numbers are pointless. we have better stuff available from 2000's to 2017 when the production of through hole matched pairs simply vanished or went big $$$. same with tempco resistors. there were a lot of group buys and small shop proprietary vendors making the min order quantity for custom spec used in the process of synthesizer repair or improvement. when you run out of tempco's you can just use a second matched pair or a second opamp in conjuction with a mini oven heater compartment on the same pcb that will exactly compensate for any change in temp. you need to redesign your circuit to do this though.

just replaced CEM3320 in my Pro One recently w/the ASM version IC & it doesn't sound the same to me ~shrug~
whatever works for you...
at least it works... considering the old chip was fried,cracked,smoked
if you can utilize old schematics making something new of your own design then go for it...
that's what eye do...
Experimentation is key
thanks for being a human here responding for posts :p
