Indeed, he is right on pretty much everything…
Very well-reasoned suggestions particularly the contextual “help”.
I’d also like better visibility overall (the two-tone grey is a bit indistinct)
I like these ideas also.
I would also like to see the time signature and tempo values in a more visible fixed position. Likely near the transport controls. Another change would be that the loop cycle points would be saved in the project so that they are remembered when you reload a project.
I mostly agree with all the above suggestions. But the one more fundamental issue I have above all others is to be able to change the background color of at least the piano roll. It’s nearly impossible to time things precisely when you’re trying to read off timings using dark gray and black lines on a slightly lighter gray background.
