I would like Cakewalk develop composition controls like a Chord Track Tool. You can globally audition a new chord progression for all your MIDI instruments with a single track (perfect for orchestral/soundtrack composers) not to mention a sophisticated Chord Assistant to instantly change chords, test inversions, and control your vocals for instant harmonization up to 4 voices that sound real.
A "multi-notes" tool would be great too! When you press a note, it generates a lot of harmonic notes too! Good when we've hit a creative block.

What do you guys think? I work with orchestral music and it'd be great!

Yes ,I would love that!

I've suggested that before when I participated in one of Cakewalk's survey some time ago...
 

"Chord Track" is number 3 in the bakery list for ideas. You can vote there and add a comment.

I put in a request for a chord track over two years ago, http://bakery.cakewalk.com/Ideas/Popular, I really would like to see this happen.  I use Cubase 7.5 only for the chord track, and then import tracks into Splat, but it would save me a lot of work to have it in Sonar Platinum, hope to see this feature soon in Sonar Platinum!
