[radiaL] controller map questions

Hi

I'm working to set-up a controller map for my Oxygen8 controller. I've figured out most of what I need, but have some questions:

1) sync.tap - this would allow me to tap a button (or key) to set a playback tempo...is that right? I can't seem to get it to work. (I'm trying to set up a key as the trigger, but don't know what to make the settings).

2) I notice some other sync options that are not in my manual (sync.div, sync.tempo) what are these for? How do they work?

3) Finally, is there a way to change a mapping on the fly? For example if I've set the modulation wheel to control a filter frequency on channel one, can I get it to change and control that same parameter on channel 2 by pressing a key (e.g. 2) and then switch back again with another key press (e.g. 1)?

Any help is appreciated.

David
