The deal with fader messages is: a message on channel 1 is received 
by the mixer strip itself, channel 2 is used to control the virtual 
instrument, channels 3 and up are used to control the 1st (and up) 
effects inserts.  I.e. the 1st effect inserts responds to ch.3, the 
2nd to ch.4., etc.

To complicate matters: if you have a regular track mixer strip (no 
virtual instrument), the 1st effect slot responds to channel *2* 
instead of 3, etc.

In order to figure out which fader messages corresponds to which 
button in a plug-in, cable from the mixer strip into a new Monitor 
object.  Wiggle the button and watch the Monitor: you should see 
something like 'F 2 12 67', meaning: fader message, channel 2, 
type-byte (-1-) = 12, value = 67.  Now transform the incoming 
controller data (from e.g. a fader pack) into Fader-12, channel 2.

Note that the transformer which converts controllers into fader 
events should be the *very last* object in the chain and should be 
cabled into the mixer strip directly.  Any intervening objects will 
break the functionality.

If you want to get fancy, you might consider downloading my 
autodemo.zip (logic section of my website) which demonstrates how to 
use an external faderbox to control plug-ins and record track based 
automation, including some tricks with presets & stuff...
