K5synth

Wow! You found a brand new unit!

There are some patches in the files section, but I don't know if it's a 
better idea to just put a link here.

I don't know if replacing the opamps will help much, because normally, 
the TL0 opamp series are used in almost everything and are very quiet. 
An opamp with better power supply rejection could help. I have some SMD 
OPA2134 waiting for a small PCB to try them. As for the other 
components, there are not much in the signal.

I frankly don't know where all the noise is coming from but I suspect 
the demultiplexing ICs (The synth uses two mono DACs and has 4 channels 
-> The DAC outputs are switched between a channel and an other 
constantly. There might be switching noise. I'd like to try to monitor 
the switch ICs outputs one day to see if there's noise (It means we 
couldn't do anything about it.) But I doubt that they are the problem 
because there would have been no noise at all when the volume would be @ 
it's minimum position.
