Inside an Akai EWI 3020m Analog Synth Module

"I'm not much of a wind player - mostly I goof around with my Casio DH's, but this EWI3020+3020m set was on ebay for a good price because it wasn't working.

I knew the 3020m was an all-analog synth, but I didn't know what the hardware inside was (and the service manual isn't floating around on the web).

Turns out it's got some solid CEM voicing, with some pretty decent matrix modulations possible, managed by the 78cXX micro. I haven't hooked it up to a midi keyboard yet, so I don't know if it's workable as a rack monosynth.

These are just some photos of the inside and outside of the unit. I wonder if this is the very last of the first era of analog synths (late 60's to mid 90's)?"

"Single board synth on the inside, surprisingly simple with minimal components..."
