And MIDI out from PC to Mac, so that MIDI data in Sonar triggers Alchemy or any other Virtual Instrument. Unless you simply want to play it with your controller and record the audio output of the synth.

I really need to take a couple of days to get up to speed w/ Alchemy. I was a huge fan of Alchemy player and bought a couple of libraries for it, but never really dug deeper than that, basically just messing with the morphing pads.
 
Taming that beast is a huge step up from using the player. 

Check out the series of Dan Worrall's Alchemy videos on youtube.  Fantastic, head-spinning stuff.
 
...bah, all but two of which seem to have now vanished from youtube?!
 
Yup: http://www.kvraudio.com/forum/viewtopic.php?p=6345145
 
Links to the series used to be up here: http://theaudiospotlight.com/camel-audio-alchemy-tutorials-with-dan-worrall/ but the videos simply no longer exist.
 
wtf, Apple?!?! :-(
 
I have them all, in a lower resolution unfortunately, as stand-alone videos (IIRC I grabbed from the former camel audio site).  I could possibly make them available on my box/dropbox account if anybody's interested?
