"'IF' your JUNO-106 has (a) broken VCF/VCA chip(s) or WAVE-GENERATOR chip(s), then this simple test procedure will show you which one(s) it is/are. Other problems with the circuitry around these chips is also possible, but in 95% of all cases, it will be one of them that causes the problems. This test is by no means final. Only an experienced synthesizer technician can perform the necessary tests to check what the exact problem is with you JUNO-106."

Roland RS-202 Schematics

1.7 meg pdf scan.
"In posts on Synth-DIY, I have asserted that the RS-202 and the VP-330 were very similar, as this was told to me by a Roland service engineer. After seeing this, and the VP-330 schematics, I'm not so sure anymore."
If anyone knows, feel free to comment.
Pics of the VieuMikro 2007 event (Toulouse-FRANCE)

Pictured here is the MOOG Song Producer. There are also shots of his C64 and SX64 based setup.
BTW, stamba mentioned there hasn't been much traffic on the forum in another post. He is right. The forum is there for you to use, so, please feel free to use it. If you have any suggestions for new categories or other, feel free to put up a post in the Everything Synth section.
Update via Stamba on the Matrixsynth forum post:
"Yes the C64c looks like the C128.. and btw the C128 is quite the same size as an Amiga500
Some audio examples :

Oberheim Matrix-12 Modded

"This is a classic Oberheim synthesizer! It belonged to a professional musician and powers on. It has been modified for pressure sensitivity and separate audio out."
Anyone know what the pressure sensitivity mod might be? The audio outs I'm guess are the individual outs for each voice on one of the side panels of the Matrix-12 although there aren't any shots in the set.
