Hi, this is minor, but will be a biggie in terms of time-saving for me (and I'm, sure, other users):

1. Can Cakewalk please get horizontal gridlines for the velocities section in the piano roll view?

2. It would be nice if the Synth rack had a "Delete all unused" button. When working on a new song, experimentation with sound/instruments can quickly add many soft synths to the rack, and often existing synths are replaced with alternatives -- leading to several unused synths that contribute to project loading times.
