Yamaha CS-5 Trouble shooting.

Postby Cymatics » Tue Apr 06, 2010 1:58 pm

Hi Everyone, this is my first post here. It's great to have a place to meet other Aussie synth heads! :)
Recently when using my CS-5 I notice this noise that happens whenever notes are played, for as long as the VCA is 'opened'. This happens even when the oscillators are turned down.
I've included a link to a clip to save trying to describe it.

- I've got the sustain and release knobs at 1 o'clock
- about 17 seconds in I open the filter so *WARNING* it gets louder.
- At 23 seconds I turned down the Oscillator volume, so you can hear the noise by itself. I then turn down the 'release' knob.
- the 'noise' knob is turned all the way down :wink:

Any idea what this could be, and if it's an easy fix?

Thanks in advance for any info.

Faulty VCA or VCA setup? Noise generator leakage from the mixer? Hard to tell without opening the machine and tracing which section it is originating at.
