Yeah... I just installed 0.2.0 because that was what was in the  
Dapper repos - I wanted to get a feel for what Om was like without  
having to install from source.  Now that I have a better idea, I'll  
do an install from CVS.

Also, I'll try a MIDI router/converter in the meantime, but it would  
be nice to have recognition of all types of MIDI messages built-in  
within Om - fewer apps open means more resources for RT performance.

Thanks for the quick response, Dave. I like your idea - I would  
describe this new node as a toggle switch: on the left of the node  
one audio in and one MIDI in, on the right side of the node two audio  
outs.  Only one audio out would be active at any given time, and if  
the node receives the specified MIDI message, it toggles between the  
outs.  To get my desired result I could use this "theoretical node"  
as follows: one audio out could route directly into the master PCM  
out (pass-through) and the other could route through an effects patch  
and finally end up at the same PCM master out.  Sending a MIDI  
message would simply toggle these routes (effect applied/no effect  
applied).

I hope such a node wouldn't be too difficult to incorporate into Om,  
because it would make Om a whole lot more useful for me (and some  
others, I assume).

Thanks!
