Korg Poly800/EX800 Users

Not sure what would cause this off the top of my head. Headphones are always a lot noisier than the main outs and let digital control noise through because it's a lower quality circuit.
Is the sound all the way through or is it just on the tail of the sound like a kind of reverb, and have you tried it with chorus off/on?

Thanks for the tip Martin,

Yes, it is much more apparent on headphones. But I'm still convinced it is there on the outputs... but very, very quiet - so not much to worry about at all.

The thing is I have used the synth a lot on headphones before and never noticed it.

Would there be any specific reason for the symptom..?

Cheers,
TOM
