I started out with, I think it was, Mixcraft 3 or 4. Upgraded to 5 and 6 and then stopped using it. At the same time I had been using Sonar, now Cakewalk by Bandlab. I have to say I'm back using M9 Pro, due to some slow loading issues with CbB, and am really happy with the improvements that have been made. Now comes the but....
However here are just a couple thoughts I have about some things that I don't think have changed or I'd like to see. It's mainly with the overall look and or feel.
The mixer: I think I prefer to see a "pan knob" vs. the slider.
I had mentioned this way long ago. The meters to me, don't seem accurate. I'm not sure what it is, but they just seem not as responsive as Cakewalk. Also I think having a PEAK and RMS reading on the faders would be SUPER handy. I use it all the time to see how much a track is peaking or not. These are their settings.
And from my other post...Combine the "output buss" with the "sub mix" buss and move it over to the right hand side of the mixer where the master track is. You could still have options to select a hardware output or send to the master. You could then just create a track "folder" to consiladate the tracks in the "track view" to clean things up.
