midibox sid stereo setup - drum and lead at same time?

If I have the midibox sid stereo setup (2 sid chips) can I play drum och the LEAD at the same time?

If so can I split the midikeyboard or Can I two midikeyboards?

No, this isn’t possible.

LEAD and DRUM are two different engines, each PIC core can only handle a single engine at the same time.

You would need a second PIC + a second pair of SIDs
