Subject: Re: [yamahacs80] Yamaha CS-60 issues: sub osc LFO > VCO not working + random bad notes

Thanks for the reply... do you mean the MIDI kit adds a toggle switch for LFO > VCO modulation? If so, where would I find that switch to change it back?

The seller showed me an emergency switch for MIDI off/reset in case of stuck notes, but never a toggle switch to control LFO > VCO modulation from sub oscillator.

Hi all,

I have a Yamaha CS-60 I recently acquired from a local seller that has MIDI kit installed. 

1. Upon testing I noticed the sub oscillator LFO > VCO slider does not work/effect the sound (however, LFO > VCF and LFO > VCA do work fine). 

What is the likely culprit for this and how easy is it to fix?

This is normal. With the added toggle switch one way, the slider works normally. With it the other way, the LFO -> VCO is control via MIDI mod wheel.

2. I notice after getting the synth home and playing it for awhile, that intermittent random bad notes would happen when playing the keys. It doesn't seem to matter what keys and it seems to happen randomly... ie after a few minutes or after 20 minutes. 

Any suggestions on where to look for fixing this/effort required would be most welcome. I'd need to take it to a tech and hoping it won't be an expensive fix.

That's not normal :(   Unfortunately, nothing obvious comes to mind.  I’d try contacting Kenton and see if they’ve heard of this.
