[A6] tones missing

[Felix Bartelt]

Hi all!

Did anyone have this problem before?

When I´m in the mix-mode and play several programms (for example Preset 2,
005 Wheeldown...) via my sequenzer some tones are missing.

This happens even when I just play single notes very slow with just one mix
channel activated. 

Somehow this doesn´t happen, when I switch the KBD Mode to "mono".

I hope someone has a solution!

Regards Felix.
