I have been having issues with East West Piano's - Sustain pedal controller works on playback but does not work for bounce or freeze. 
I am contemplating a VST recorder since recording digital produces plenty of clicks and pops if I have a lot of tempo changes.
Before I buy the VST recorder though I wanted to ask if anyone has used Synthogy Grand Pianos with success and no issues with freeze or bounce in Sonar?
Thank you
John
