[linux-audio-user] sequencers comparison

I know there were some discussions not too long ago about sequencers, but i'd like to ask the questions in a slightly different way. I'm looking for a decent sequencer for Linux. It's not required to be a "Logic/Cubase/Pro Tools/Sonar killer" (although it would be great :-D), but i'd like it to perform a few basic tasks well. Must-have features: - record and play multiple MIDI tracks - record and play multiple sound tracks - MIDI and sound must be able to blend freely in a project (i.e. record and play arbitrary combinations of MIDI and sound tracks simultaneously) - overdub multiple sound tracks into one (or two) - fine-grained MIDI editing (edit individual keystrokes' parameters such as velocity, timing adjustments) - automatic tool to move slightly off-beat keystrokes to a fixed temporal grid which is defined in the program (therefore making "perfect performance" timing-wise) - sound editing abilities (features such as "snap to pass-through-zero" would be nice) - LADSPA filters - play a metronome through a MIDI or sound channel - works with JACK and ALSA - does not crash Nice-to-have features: - the editors (MIDI, sound) and, generally, the whole app must be user-friendly and inspiration-friendly :-) (when the inspiration possesses you, it's not a good thing to start fumbling through some crappy interface and make a thousand mouse clicks just to do some trivial operation - every second lost is precious) - music notation - some kind of interoperability with related apps Essentially, in the free software world, it's either Muse or Rosegarden. Has any of you extensive experience with both applications? Which one is a better fit for the description above? Thanks, -- Florin Andrei http://florin.myip.org/
