Problem solved:Found an old post that had the answer from October 2012:
http://forum.cakewalk.com/Controlling-guitar-rigs-effects-realtime-under-Sonar-X1-m2689668.aspx Robert Bone had the same question and N.I. sent him the following answer:
If Guitar Rig is already loaded, remove it before you change the Plug In Mode. You need to go into the Plug In Manager, you select Guitar Rig 5 click on Properties and set this Plug In to be loaded/handled as Instrument. Load Guitar Rig as Instrument in the Audio Track Then you need to create a MIDI Track, -input is the Device (keyboard MIDI Controller type of thing) -output has to be routed to Guitar Rig 5. That is it basically.
Robert Bone said to:
1. Insert an audio track and a midi track
2. Inserted GR 5 Synth as a
SYNTH in the audio track FX bin.
3. Changed the midi track input to my midi controller, and the output to go to GR 5 Synth
4. Went back to the audio track, opening up the GR 5 Synth effect
5. Right-clicked on a knob and clicked Learn, then twirled a knob on my midi controller
6. This time, the midi learn function worked perfectly
Everything is fine now. I had also received a PM from
scook with helpful suggestions.
Thanks to everyone who responded and helped.
