Thanks Jaakko, it was a big job, those machines are diabolical, and I didn't have extender cards which made it quite challenging. The soldering is poor on the boards, nasty flux, and the clock oscillator had eaten away at the solder on parts of the CPU board. Dry joints, bad IC's, bad headers, antsy tantalums, you name it. Built like a Jaguar, or a Triumph - never use 1 part when you can use 3. Reminds me of working on ADR stuff - difficult to reach everything. Those zany English... I just noticed that the echo preset doesn't work properly either, but the Ambient, reverse, nonlin, hall and room seem OK. I wonder why some algorithms work and others not?
Still, I shouldn't complain, a friend of mine is fixing 4 Publison Infernal Machines at the moment, he has no schematics, and Publison scrubbed the markings off all the chips to protect their circuit ideas. He has them pretty much going though.
Anyone know how the algorithms are stored in the rmx-16? Not exactly DIY, but I know there are some great minds in the Lab... I don't do too much DIY, I spend my days repairing synthesisers but I do have 2 Gyraf SSL boards completed, I am just waiting to get around to putting them in cases. (Many thanks to Swedish Chef and Kev) :guinness:
