You have no idea how badly I want to stop using Windows. It keeps losing the USB audio interfaces, keeps wanting to be reactivated every time I change the hardware, and doesn't seem able to record in 24/96 without glitching.
What I've been doing lately is scoring in Sonar, laying down the softsynth tracks in Sonar, and then exporting it to MIDI and laying everything else down with Rosegarden in Linux. The timecode locking in Sonar appears to drift when dealing with epic songs (11-26 minutes) even though it's supposed to be doing a full chase. This might be fixed in V2 of course, but it doesn't solve the intrinsic problems with Windows.
