Doug Robinson Posted December 4, 2014 Share Posted December 4, 2014 If you guys have any suggestions, lay them on me please. I live in rural central mexico, and the nearest service center is 5 hours away and I'm not even sure they've ever seen one of these. It's been stored in my studio for a few months. I took it to a duo gig the other night to discover that in the octave two below middle C, none of the black keys produced sound. Kinda hard to do left hand bass like that. Frustratingly--but maybe it's a good sign--the audio came back on one of the keys before disappearing again. I turned it off and on several times, but nothing helped. Anyone?

Dana. Posted December 4, 2014 Share Posted December 4, 2014 Is your version red or black? If it's red, you may have the infamous faulty RH3 action. Were you storing it upright or flat? Link to comment Share on other sites More sharing options...
J. Dan Posted December 4, 2014 Share Posted December 4, 2014 You may want to open it up and just make sure all ribbon cables are firmly seated.

Doug Robinson Posted December 5, 2014 Author Share Posted December 5, 2014 Red, upright. Am I screwed? Doug Robinson www.dougrobinson.com Link to comment Share on other sites More sharing options...
J. Dan Posted December 5, 2014 Share Posted December 5, 2014 Is your version red or black? If it's red, you may have the infamous faulty RH3 action. Were you storing it upright or flat? As far as i know, symptoms of the original RH3 action had to do with double triggering and irregular velocity response. Never heard of a zone going out, the fact that it came back momentarily suggests a loose connection. Ribbon cable connectors are notorious for this sort of thing.

Doug Robinson Posted December 5, 2014 Author Share Posted December 5, 2014 I will open it up, thanks. I hope I can figure out exactly what I'm looking for--a loose ribbon connector, right? Doug Robinson www.dougrobinson.com Link to comment Share on other sites More sharing options...
JohnDoe Posted December 5, 2014 Share Posted December 5, 2014 Try this first: start with the SV in horizontal, playing position, then turn it around 180 degrees (keys pointing to the floor) and shake it gently, then back to horizontal. This helped when my SV had a similar fault and I always store and transport it laying horizontal. "This is my rig, and if you don´t like it....well, I have others!"

Jaspla Posted December 5, 2014 Share Posted December 5, 2014 Jazooo, I agree that it is likely an internal connection issue - had one of these once. YOUTUBE clip below shows the BEAST being disassembled - if you can only slow it down.... This KORG Forum thread (Scroll down; Mon Dec 31) http://www.korgforums.com/forum/phpBB2/viewtopic.php?t=77515&sid=d0b7168927da11624f2401a071b548bb talks about the Service manual being posted on the Korg SV1 User page on Facebook ...files section, right bottom ...never had mine apart...usually sat in a 'studio' environment. ..my recommendation. If you take it apart, if possible setup a digital camera/recorder on a tripod...to record your dis- assembly...to facilitate the re-assembly... ...as has been suggested, tilting, shaking it first may be the best first step....

Doug Robinson Posted December 5, 2014 Author Share Posted December 5, 2014 That sounds exotic--I'll try it! Thanks, everyone. I really appreciate the help and will report back after I do the above. Doug Robinson www.dougrobinson.com Link to comment Share on other sites More sharing options...
JeffLearman Posted December 5, 2014 Share Posted December 5, 2014 At first I agreed with Dan: most likely a loose connector, which is an easy fix once you get at it. Especially because it affected only certain keys. But thinking about that, it would be unlikely to affect only black keys. I wouldn't expect the encoding hardware to single out black keys. But, one never knows, and it's definitely worth a try. It's also possible that there's a loose part in the action itself, affecting that section of keys, and only the black ones. If so, it's also possible you could snap something back into place. If tilting and shaking it helps, then DEFINITELY open it up, because more tilting and shaking will cause it to fail again, not good for the gig. Good luck!

AnotherScott Posted December 5, 2014 Share Posted December 5, 2014 Also, what look like helpful disassembly instructions at http://www.justanswer.com/electronic-musical-instruments/6i93k-hi-own-korg-sv1-88keys-one-white-keys.html Maybe this is the best place for a shameless plug! Our now not-so-new new video at https://youtu.be/3ZRC3b4p4EI is a 40 minute adaptation of T. S. Eliot's "Prufrock" - check it out! And hopefully I'll have something new here this year. ;-) Link to comment Share on other sites More sharing options...
