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?
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.
As an example, if I'm playing a scale and I hit one of the keys (ie a middle C), that will give a severely out of tune note. Coming back to the key immediately after and its in tune again.
Any ideas what could cause random bad note behaviour across the keyboard? It doesn't seem to be a specific voice, but I have no idea what is triggering a bad note to occur randomly. Perhaps the MIDI retrofit messed something up, or when the synth was transported to my place the voice cards got jiggled around from bumpy driving?
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.
Thanks.
