Trying it out tonight. So far it's pretty slick but not sure if I can beat the Sunday night $99 deal deadline.
Someone said the GUI was kinda cartoonish. Nicely, all the GUI files are in a folder (mixrez) and can be repainted like Sonar's. So custom themes can be made for it.
Has Multidock style views. Big + is the Docked views can be displayed on a separate monitor.
Clips have their own play, mute, loop buttons. Very handy for editing.
MIDI editing is probably not up to Sonar but I haven't got that far yet.
Has cool MIDI Learn button for setting up your controller. Just did mine (transport only controller) and couldn't have been easier. The missing Stop button means I have to use the controller's Play button for Play & Pause. No RTZ button either.
A CON is the Time Ruler only displays Beats or Time, not both. Worse yet it affects both the Ruler and the Now Time. I like to have them showing opposite stats.
Only glitch I'm noticing so far is the softsynths tend to freeze up while playing them with the QWERTY keys.
When played with a controller the latency is very noticeable. Haven't seen how to adjust that if you can.
