Does loading a multisetup interrupt the sequencer or is it possible 
to load one while the sequencer is playing?

For instance, if I have a pattern running and I load a multisetup 
which has the exact same settings for preset, volume, pan, and so 
forth but has different Direct Pattern Access assignments, will I 
hear a hiccup or will the multisetup load seamlessly?

Basically I'm wondering if it's possible to change DPA assigns 
throughout a couple-hour set without stopping the sequencer...

And are we ever going to see the full sysex spec for the Command 
Stations?
