Hi,
 
I run Sonar X2a and I can't select "Left channel input" in the included TH2 Producer plugin. All routing options appear greyed out when I click on the guitar.  It default to "stereo input" so the sound is hard panned to the left cause I use the left input on my sound card. I can cure this by panning my guitar signal 50% to the right in Sonar but I find this not ideal...
 
Is this a "feature" which is unlocked in the full TH2 version? That would be dumb I think....

Change your 'track interleave' to mono and try it. If not, you can use the 'channel tools to pan stereo tracks. for this plugin, if you have a stereo track, then it will process a stereo track. If you have a mono track, it can process it in mono. Check out your Track Interleave. I

I cannot tell you why the input selector in TH2 Producer does not work for you. The choices are there for me. What about making the selection in the input drop down for the track instead of the plug-in?

Scook, I can tell you why your works and his doesn't. Yours show up because your track interleave is set correctly and the poster's is not.

Yes, track interleave does govern the plug-in setup. If the plug-in is inserted when the track interleave is set to stereo, the plug-in will present input selections. If the plug-in is inserted when the track interleave is set to mono, the plug-in input selections are greyed out. Subsequently changing the track interleave does not affect the plug-in input selector.
 
I just dropped the plug-in in the track so the interleave was set to the default, stereo.

Hey thank you guys I'll have a look at this. :D
