OK. So I've been auditioning potential replacements for Sonar and I must say it's depressing. Seriously. I just want to cry. Mixbus: not even close to Sonar in usability or sophistication.
Don't buy Mixbus without trying the demo first since they won't give you a refund. I found out the hard way. I own Studio One 2 Artist, looks nice, but I would have to buy a higher level of the program for it to use any of my VSTs. Reaper has potential, but I went to add BREVERB to a track and it said "BREVERB is only licensed to be used on Sonar". That will probably be the case with most of the Sonar plugs. Will I no longer be able to use Dimension, Rapture, SI-Bass, SI-Strings, Sonitus, BT, Meloetc.? Probably not. And I was just getting going with it since I retired and now have the time. This year I wrote and recorded four new songs and numerous gig recordings for the band I work with using all the great new tools in Sonar that will not be easy to replace!
Folks, we are seriously F'ed! I'm considering quitting this wonderful hobby I've had for most of my life because it would be too much for me to start over. I may still look at Cubase and ProTools before deciding what to do. Cakewalk: this is the biggest disappointment I could have imagined.
