There's a limited sale by Magix for ProX 3 Suite...which normally sells for like $1400....but you can get it for only $149.
I'm not just pimping it because I use ProX...it's a pretty robust piece of software, not to mention the add-ons they are including for free.
Might be a great way for the Sonar guys to get out from under the Cakewalk collapse...or for anyone looking for a pretty serious DAW app + extras.
Samplitude ProX 3 Suite + Extras - $149 for only a few days!
