CASIO MT30... and more

CCCL has taken (yet another) detour since my last blog.
As I'd previously said: it became apparent that building many of my rediscovered/resurrected circuits into self-contained battery powered units was going to be impractical, but that I was not abandoning that 'format' entirely. Well over the last week or so while 'rationalising' our (not inconsiderable) archive I found some more discarded effects pedals, a Casio keyboard, a drum machine, a percussion generator (a slightly clapped out 'Clap Trap' to be exact) and a drawer full of original synth books and brochures from the 1970s'. And surprisingly (to me at least) all of these units still worked.
The Casio keyboard, a heavily modified MT30 (see below), still sounded great, although the extra custom pots and switches are noisy/failing and all need replacing. PLUS... I also found few circuits and instruction sheets of further MT30 mods I'd never got around to installing. So first on my long CCCL 'to do' list is to renovate the MT30 to it's former glory and add the extra mods. This (particular) MT30 already has a very unique sound, due entirely to the mods: a variable clock rate, adjustable vibrato, octave shift, variable digital distortion and an LFO for extreme modulation. I'm also going to include a ring modulator and a band-pass filter.
