It looks like VR6 may be my friend in the tuning issue, I'll check it tonight. http://www.guerillasofsoul.com/chad/sh101/101calibrate.txt There is also a 300dpi scan of the service manual that went up a few months ago. It's much better than the very old one floating around the web. http://matrixsynth.blogspot.com/2009/03/new-scan-of-roland-sh-101-service.html Also, perhaps a 1M resister in series may make a better simple scope probe than a straight wire? thx, Scott S.
