Hi all, Thanks for all the help so far! I've downloaded myself a nice-sounding drumkit soundfont, and have it loaded by fluidsynth (using qsynth). I played with the settings in Rosegarden, by clicking my right mouse button on the appropriate MIDI track name. I can now hear all the samples when I click my left mouse button on the notes at the left of the notation editor. However, when I throw a few notes together and press 'play', I only hear the note(s) which falls directly under the playhead at the moment 'play' is pressed. Rosegarden seems to be sending the right MIDI notes somewhere - the little indicator flashes away just as I would expect. Correspondingly, the indicator in qsynth only flashes once, as the first beat is played. Have I configured something incorrectly, or is this a bug? Please let me know if more (or clearer) information would help. I did have this working some months previously - although I was never confident that I understood fully which MIDI output to pick in Rosegarden (especially when I had more than one instance of fluidsynth). Thanks Michael Nelson
