Discussion about the Korg PolySix synthesizer

Hi Friends
I recently did the adjustment procedure and I found two problems.

The first is: not all the leds BANK A-D, PROGRAMS 1-8, MANUAL and TAPE
ENABLE lights up when i turn VR1 from left to right, but every time I
pass a certain point of VR1 leds light up in different combinations.
[[-(]

I have to say that I can proceed to the calibration procedure anyway.
But I don't know If the result of the calibration procedure  could be
better if all leds light up instead some of them.

The second i found is that when I regulate MG speed I can't obtain a
cycle of 10-40 sec, but just 4 sec,  a very short cycle.  [[-(]
For this problem have I to check IC21 and C19?

Any suggestion?  [:D]

Thanks

Aniello
