Yes, you needed a special test card. Don't attempt to run these tests without one. Wow... fixing synths I find it interesting to see what kinds of mistakes a designer can make. Power supplies that have a cap that fails in very bad ways, red glue, and this - making your diagnostics a separate piece ...

The Korg Wavestation service manual makes some very confusing reference to a diagnostics test. So far I have not been able to decipher this language to figure out how to start the test. Specifically it seems to reference "this test card" but only once. It doesnt mention any key commands to start the...

Just for anyone reading this, I was told on another forum that the runaway portamento is a known issue and autotune corrects the issue temporarily. I tested this and it works for the most part, however is pretty annoying to deal with as the portamento always comes back. FWIW far as I can tell ground...

After sleeping on it, this am I took another look at ECO 120 which details the board changes for digital portamento. It looks like they simply removed the circuitry that does portamento. That circuit feeds UPC signal to a 3080 opamp which looks like it originally handled the portamento. It looks to ...

My OB-XA is an early version and came with XA-F0/1 firmware, tuned fine and worked normally inc portamento. When I installed XA-GA0/1 the upper portamento went funny and so I went back to F firmware. Now that Ive installed Encore MIDI the portamento issue is back (I assume because they emulate G fir...

You sir are a gentleman and a scholar. With that part I was able to fashion a little adapter and, viola!, the strip works perfectly. Doesnt even need any calibration, out of the box its got a nice sensitivity to it and the clackiness is gone, feels like youre playing on angels pillows. Thank you for...

Cool, part is on order Ill hit you back when I have some results. Really appreciate the help!

Thank you very much for hopping in here this one is really tough for me to get fixed. So unfortunately I have already tossed out the old one (I kept the molex connector) because I stupidly assumed I had the right replacement part. I bought this piece from Syntaur which someone told me was the same p...

Hi all, I am looking for a replacement aftertouch strip for a DX5. Its 76 keys length and needs a molex connector like the DX7 strip does. I have been unable to find this part, wondering if anyone can help me locate a suitable replacement? https://syntaur.com/images/x1659-Lg.jpg.pagespeed.ic._24BTqC...

No clue about the shop but those modern replacement boards came from a guy in Germany who sells them on eBay. You wont get super amazing support on those boards but they do work, I have used them. https://www.ebay.com/itm/266021365140?hash=item3df01be594:g:LjEAAOSwQjthN61e&amdata=enc%3AAQAHAAAAsKD%2...

Nice!

Hey Jeams_420 this track was a 1987 piece put together by Mike Stock, Matt Aitken, and Pete Waterman. They were pretty hot stuff and had loads and loads of gear at the time. Check out this old interview about their studio from that time period: http://web.archive.org/web/20080617221659/http://www.st...

Yeah totally, I imagine that someone might someday have a similar issue. I have this all working now but I still cannot get an existing SY-77 disk file to load. I can send patches over MIDI though and save/load at will and that is really cool. I was kinda hoping the drive would pretty much come with...
