When converting CC MIDI data to automation in SONAR, be aware that you may be giving up resolution. SONAR appears to only output CC values from track automation at an approx. rate of 24 parts per quarter note. In many cases 24 PPQ is adequate, but possibly not for controls that may exhibit zipper effects or when the slope of the MIDI data is very steep.
The follow examples demonstrate the effect.
Image #1: Original CC#1 data hand drawn in the PRV Controller lanes.
Image #2: Same CC#1 data converted to track automation.
Image #3: Track automation recorded into another track using loop back recording. Notice the reduction in CC density between 4:03 and 5:02.
Hope this helps,
