    What a great setup! That’s a great idea about the rack panels for the bottom. I’ll probably do the same. Did you use angle brackets bolted to the rack panel?

    Great track by he way!

    It’s not my setup or track, I just found that link :D

    (I think it was on the Matrixsynth blog)

    im allllllllmost there. alllllllllmost. i only have one of the drum machines (which are RAD), and one mini synth. but i have an old school space drum and two old EH sampler pedals. my plan is pretty much the same as this, build a huge board i can run connected to my roland kit for just pure 2-person sonic insanity.

    Sorry aabout that DiscoFreq. Many thanks for the link!

    I’m thinking of mounting mine to a rack drawer and putting it in 4U rack with my old Roland DEP-5.

    I’d still love to add a guitar input and/or MIDI functionality if it’s possible. Anyone done that?

    Danieldanger, thanks again for this thread. It’s been cool to ressurect mine from the dead!

    Wow, thats a lot of wires. it must get really confusing with all of them sometimes, especially if you unplug something or move something.

    i thought the dude with two axis fuzzes was the coolest person on earth, now i know it’s whoever has this set up.

    btw, ehx man, that was like observing a doctor coach someone through open heart surgery on the phone.

    This is my first time seeing this pic. Holy Analog!!! That looks like way too much fun. I totally need an EHX Clockworks or a Sequencer.

    Hi all.
    I bought an EH-0400 an I’m very enthusiastic about this synth, I love it.
    It works fine, but it have some triggering problems and it need some little repair.
    Someone that have it can kindly post the instruction manual?
    Please please please! I will be very grateful.

    Hi all.
    Me and an expert luthier we are trying to give a new life to the eh0400. It lives now but with some triggering problems and not with the complete features.
    So, i ask you a little help:
    – where (and what a kind of) I can buy the “Q” switch that is broken?
    – We don’t understand how the keyboard works.. Why conductive? why conductive stripes on a plastic foil? I don’t see anything that close the circuit. I want to replace it but i don’t know where find that material..
    If someone have the manual i would be very grateful if he send it to me. Also via mail ema@gringoise.com.
    thank you in advance ;) The improvements will be well documented in this forum.

    No idea on the switches but any comparably sized switch should work.
    The keyboard works by connecting resistors together when the keys are pressed. This completes a circuit and causes a tone to be heard. The row of resistors at the top of the keyboard are the tuning resistors.

    This very thin strip right here.

    i really don’t understand.. It sound even if the foil is detached from this part. It is the whole contuor of the keybord that close the circuit?
