There was several threads about subj. in this forum...
Out of the box, with stock/official plug-ins:
Mackie MCU Pro (+ XT when required)
Behringer X-Touch ("big" one)
Presonus Faderport (one strip version!)
Roland A-Pro keyboars
Naktar Impact (not Panorama!)
Softube Console 1 (not really good as a general Sonar controller)
Obsolete devices with original Sonar support:
Roland VS-700 (problematic with Win10)
Roland VS-100 (as one strip controller)
Frontier AlphaTrack (better with not official plug-in)
Good not official solutions for:
Behringer X-Touch Mini
Behringer BCR2000
