I just got on my hands a Polysix but it seems to produce a lot of heat on the back side where the KORG logo is located.
Also the LFO (MG) seems to produce a low level noise that shows on my Mixer.
If i turn the MG level up my mixer goes all the way to red and i hear a low hum. i can change the hum speed using MG frequency.
Any ideas? is that normal on a Polysix? Easily fixable? I really like the synth and would like to buy it.
Greetings!
p.s. sorry about my English
