> Hey all,
> Strange behavior from this AX60:
> In split modes 2-4 and 4-2, all voices work. I can simultaneously hear 6 pitches when I hold 6 keys. the balance slider functions normally, mixing between the two patches.
> In single mode and in split modes 6-0 and 0-6, only voices 5 and 6 are sounding. I can hear the other four faintly in the background. I have checked the CV going to the VCA, and it's a consistent 4v across all CEM3394s.
> The signal paths for the mixed voices are split into two groups; 5 and 6, and 1 thru 4. What I don't understand is why all voices would be present in split modes but not in single mode.
> Any ideas?

> Thanks in advance,Greg
