Modular synths

    Is anyone here into modular synths?
    Does anyone here own a modular synth or has heard of them before?

    back in the 70s, i used to have fun with the Moog patchboard synth that our Music Department had. had a couple of Teac 3340 4-track tape decks also.

    An actual moog modular, wow...

    Here's a recent photo of my friend Sudhu attempting to refurbish the Moog I learned to build electronic circuits for, also in the early 70's. We had one of those Teac's and a Sony 4 track in our studio as well!


    I later built my own signal processor, using some commercial modules and a bunch of my own design. Last time I looked it still worked...

    Did you have a question about them?

    What sort of signal processor?
    Envelope follower, pre-amp, effect, audio-CV?

    Here is my eurorack modular synth, it is starting to overflow somewhat.

    Cool. Who makes those modules?

    Here's a funky pic of mine:
    As you may see I never got around to labeling anything...but fortunately I made a map and color coded the in/out/control jacks...

    Mostly from left to right:
    One audio VCO and one fancy VCF, both from Serge Systems I think.
    Two more VCF's of my own design, using chips from another synth company.
    A ring (balanced) modulator.
    Two analog CCD phase shift/delay lines (not very good but kinda fun).
    A really crazy pitch shifter (also using CCD delay) hacked out of a cassette tape recorder
    that was made to listen to tapes at double speed -- totally whack sound.
    Two kinds of distortion circuits.
    Four attack-release generators and VCAs
    Slow function and noise generators, mixers, envelop followers, and other stuff I don't even remember...

    I also made a similar digital controller box based on a (Radio Shack) Trash80. But it has gone the way of the dodo.

    You can hear some of the results (circa 1982) here: http://www.etantdonnes.com/Mobsters/
