I've managed to get Rosegarden 4 to compile and run on my amd64 CURRENT box (running it with the --nosequencer switch to prevent crashing on startup). Perhaps with this device, the sequencer in Rosegarden may actually become useable! I've considered submitting a port of Rosegarden 4, but am hesitant to do so with the broken sequencer functionality. All of the other modules seem to work pretty well, though, especially the much-improved (over the old Rosegarden we already have in ports) Notation Editor, which I've used to create and then export MIDI files. I may just have to find a USB cable for my Yamaha S03 keyboard and see how it goes. :-) Thanks! -- Conrad J. Sabatier <conrads@cox.net> -- "In Unix veritas"
