Way back, when Cakewalk was MIDI only, there was a great little program you offered called
Cakewalk Live that allowed you to easily play back cakewalk sequences on stage. It was playback only, with the emphasis on getting thru your set list. I think loading the complete Sonar Platinum for performance on my laptop is a waste of CPU overhead, when all I'm gonna do is execute a playlist. I think a new endeavor,
Sonar Live perhaps, Playback only, with a revamped customization for lyric view, sys x view, playlist view, etc. would be a great tool for us working musicians.
