Staff view. Please, staff view. I don't expect Sibelius level quality, but as much as I can appreciate PRV, it's not always the easiest if I'm trying to go fast on stuff I can't physically play in. Being able to enter the notes in staff, then go into PRV and humanize them is really important.
Even more important is being able to VIEW what I've programmed in accurately. Last time I checked, tuplets still don't go up past a triplet, no quintuplet, sextuplet, and certainly no way to specify, for instance, in 5/4 meter, that the last 3 beats are to be played as a tuplet of 4:3 (4 quarter notes in the space of a 3 quarter notes). Having to resort to 2/4 and 12/16 alternating to get this effect without bedlam in the staff view is annoying, as is manually programming it in through PRV. No real way to check if you screwed it up either if it won't display properly short of exporting it and loading the midi into something that will display it musically, even if not 4:3 but simply 4 over the notes would be a life saver.
PLEASE put this high up on the list. I know not that many people use it but for those who do, it is a practical frustration when sketching something out as a demo, which is when staff view is very useful. Cakewalk has amazing MIDI abilities under the hood but they tend to remain under the hood in staff view, and even entering the notes is a pain sometimes, though I've seen improvement on that in new updates (!!!!).
If I enter a quintuplet, or anything other than a triplet, it won't display in staff view, and I end up going into PRV, doing arithmetic about the number of ticks and aligning them, then switch to staff and it's gibberish. I end up using other programs to enter this kind of MIDI data at this point, which have their own frustrating limitations (I love that in Sonar I can have spaces autofilled and that CbB moved the note values seen in PRV to the staff view - this only makes me want some of the advanced features more!)
Making it easier so what you see in PRV looks like music in staff view is what I desperately want... Doing a simple quintuplet (just a /5\ instead of the normal /3\ for a whole note doesn't look good in staff, and is a little better but still inducing a migraine in PRV by trying to see the edges.

When it could look as nice and neat as this triplet:
The above triplet is nice, neat, and easily recognizable. I don't see why that can't be done with a 5, 7, or more complicated rhythms since it can be programmed in. I love that the notes have been put right next to view/tracks, so I'm very optimistic but still not having the ability for the program to recognize that a series of 5 notes consisting of 768 ticks in a bar with 3840 ticks is shown in a weird way, not the same as while a triplet, a series of notes consisting of 3 1280 ticks in a 3840 tick bar, is recognized so easily is frustrating since there are 4 over 3 substitutions, 2 over 5, etc, that can be played back perfectly but not displayed right.
I'm not expecting this level of implemention:
https://imgv2-2-f.scribda...25bb82/1534795873?v=1, but getting simple tuplets down of 5, 7 and 9 and other small changes so that what I enter in PRV that are exact lengths reflected back as something I recognize in staff view would make a big difference. Cakewalk's MIDI engine is powerful, which is why it's so crippling to have to run to another program to visually enter anything past a triplet quickly and see it displayed as intended.
Cakewalk is not software for creating scores. I don't expect it to be, and I don't expect dynamics and techniques that live in the MIDI to be expressed via the staff view fully, but basic problems like not displaying what I showed above are less about music printing and more about the inability to view the same data in the program while working and see it displayed in a musical way, which interrupts workflow. If I had a request, it would be for these kind of improvements since I still use staff view quite often, especially while programming drums on demos or scratch tracks.
Other notation programs insist you fill in the rests before you move on which is time consuming, and I'd do much more work in Cakewalk that will eventually end up in Cakewalk because while I have more freedom to move notes without worrying about filling in the rests, I can't be sure what I entered is correct due to the staff view issues.
And thank you again Meng for the outreach, I truly appreciate the invitation for requests and could not be happier with what has happened since Bandlab released Cakewalk by Bandlab!
