After compling the latest Rosegarden and compiling the kernel to go with it (1000hz hw frequency), I am very pleased with the Rosegarden. This one is just about ready to play. What is needed now is interoperability. Many of us who are going over to Linux are coming from other OSes. We have loads of data for Cakewalk, Steinberg and Protools and would need to get it into Rosegarden, Muse, Ardour, etc. No way Jose right now. If paid software publishers would realize that interoperability and freedom of choice will not hurt their sales and possibly improve them, we would not need to reverse engineer to get it but right now, that's it. Sonar files consist of a stereo audio and mono audio catchalls and the main file with MIDI data, track properities and pointers to the two audio files and MIDI data (or all this bundled together). Should be not too difficult to hack, but still ... My Jammer Pro and Ntonyx software to produce the MIDIs is Windows only and is not going using Wine. Still no ALSA support for my Dman2044 either. Someday.
