Korg Mono/Poly

Hello

There are two noises:  a 50Hz "buzz" from the power line and real "noise".

The buzz sounds more like it is induced by neon light or something 
similar. But it might be the transformer itself. I can't judge that from 
here.

The noise seems to me the normal noise of the synths output (it _is_ 
noisy to a certain level), but the internal signal seems to be low. That 
is normal for 50% Level. Use 100% Level for VCO1 and make the recording 
again.

Basically: the signal level in the MonoPoly is that way laid out, that 
you can work always with all VCOs at 100% level. There is plenty of 
headroom. If you do not use this headroom, you will hear the noise.
