<p dir="ltr" style="margin-top:0; margin-bottom:0;">Does it play any MIDI by irself untouched?</p>
<p dir="ltr" style="margin-top:0; margin-bottom:0;">Does it play all pressed keys or randomly swallows some of them?</p>
<p dir="ltr" style="margin-top:0; margin-bottom:0;">Can you post MIDI-OX log or screenshot showing this behavior?</p>

<p dir="ltr" style="margin-top:0; margin-bottom:0;">My guess is intermittent connection of jacks board cable, or jacks cracked soldering. </p>

I picked up this one second hand and really like the weighted action.<br>Since the off there has been a problem with some rogue midi output signals. Plugging a volume pedal into the volume socket seemed to solve it. Now however after a couple of years of use I am getting random and unstable outputs and it’s unusable. I tried changing a couple of the electrolytic caps as I had spares. The board generally looks OK and the settings functionality and the LEDs all seem to be working fine, so I think there’s not much wrong with it. If anyone knows a likely point of failure on these boards please give me a shout. <br><br>I thought about replacing the crystal as it looks a bit aged. Marking is 24.0MHz, HCJ-30 02-02-57. Would any 24MHz crystal do? Or am I on the wrong track.<br><br>Alternatively if there’s a way to put a whole new DIY circuit in there I could go that route. They’re Fatar keys I believe, with aftertouch.<br><br>Thanks.<br>M<br>_______________________________________________<br>Synth-diy mailing list<br><a href="mailto:Synth-diy@synth-diy.org">Synth-diy@synth-diy.org</a><br><a href="http://synth-diy.org/mailman/listinfo/synth-diy">http://synth-diy.org/mailman/listinfo/synth-diy</a><br>Selling or trading?
