Heya, finally had the opportunity to make the jump from SPLAT to CbB super impressed at all the changes so far; as someone who does a lot of ITB stuff on some projects, the piano roll improvements alone made the jump worth it!
 
Now that things seem to be rolling forward again for Cakewalk, thought I'd revisit this suggestion I made some time back. Lots of VSTs operate with keyswitches and CC, whether it's selecting velocity layers, articulations or even different playing techniques. It'd be incredible for workflow if we could customize visuals on the piano roll for this per track (and obviously save them as track templates) so that keyswitches and CC thresholds, etc are easier to parse at-a-glance rather than flipping through VST user manual PDFs every couple of hours. Here's a mockup example for Prominy's V-METAL guitar library.
 

 
Similarly, CC lanes and even the velocity row could show specific thresholds for the VST in question.
 
Ideally, if piano roll themes were per-track (defaults to global if no per-track data) and included BG color selection, text color selection, and label text per MIDI pitch, that'd accomplish something very close. Ditto on CC lanes, although that'd have to also then add number of divisions, where the boundaries are on each, etc.

Derp, right after I hit post and got back to the forum front page, I see a big stickied topic labelled "Feature Request". Feel free to lock this, posting this there instead.
 
My bad!

What you can use is a drum map sounds strange to suggest but if you use one of the blank or pass though maps you can add the Key Switches to the map.  It may not show the black and white keys but it will show MIDI note number and Pitch.  i.e. note 5 / F0 note 6 /F#0 etc.

It is good idea!

In addition to drum maps, it is also possible to expand the .Note Names section of Master.ins to replace the keyboard display in the note pane. That said, both drum maps and the note names feature could benefit from updates.

I agree, it would be an excellent enhancement if you could just type in arbitrary descriptions for any keys and have them saved with the MIDI track. Even better if they could then be saved to and restored from track templates. Not a replacement for drum maps, which can do more than just label MIDI notes, but far less work.
 
In the meantime, like others here I've devised my own system that works well for me.
 
I have drum maps set up for my most-used instruments, and use separate MIDI tracks for notes and keyswitches. It was time-consuming to create the maps initially, but it's been well worth it.
 
For example, a string section will typically have 8 MIDI tracks: one each for violins, violas, cellos and basses plus one additional track for each of their articulation sets. 
 
You can then take it one step further and build a track template that builds all these tracks and loads the instruments with a few clicks. My strings template automatically creates...

• a "Strings" track folder
• 8 MIDI tracks, with appropriate drum maps
• 4 audio tracks
• an aux track to sum all 4 audio outputs (saving the need for a separate sub-bus)
• and loads a multi-out instance of Kontakt with 4 instruments
• with everything properly routed to and from Kontakt

I reckon doing all that by hand would easily be a 30-minute process (longer if I make a mistake :)
 

I just wish the bandlab app (android/ios) would get a piano roll. It's a must have tool, all my peeps on there who only can use a phone want this feature lol, sorry, not exactly related but uh... piano roll. please.
