I've been using GP since V3. I downloaded the trial version of GP just to check out. The good points:
+ MDI interface that is Multiple Dokuments open in the same window, finally.
+ The ability to move/swap voice
+ Its possble to select bars from the overview at the bottom of the screen
+ Full screen view (dont know if it disables screensaver, but it should)
+ New cursor while playing, much clearer
Some negative points
- Took me about 2 minutes to encounter a bug, select something else than a full bar and the countdown function keeps on forever
- program is big an bloated, noticeble laggning on my computer
- Its no longer possble to get to the intrument tuning from the track overview, a right click would be easy to add
Personally i dont give much for the rse engine as i use the program mainly for practising. The speed trainer althoug a godd feature has not been improved
