You can import waveforms in MusE as well (not drag and drop at the moment
Biggest problem with this approach is that it's much harder to "drive" these
samples in a sensible way since you can no longer use midi. Pitching is a
pain, you would need to pitchshift the samples externally and import them
If you have looped samples you might also have significant problems getting it
right... As far as I know _no_ app in linux-land can currently do this in a
sensible way. (I'd be glad to be proven wrong though.)
... on a related note... I've pondered a bit lately about implementing a
timestretch subsystem in MusE to make it possible to dynamically alter tempo
and have the audio tracks adapt to the new tempo in a non-pitchshifted
sensible way... (I guess acid can do this kinds of things ?) It would be a
quite powerful feature if done correctly...

I'm not sure how advanced simsam is, but for mixer app you would probably fare
better with one that is multichannel, Ardour seems the obvious choice (though
it's much more than a mixer, ofcourse), possibly there are others.
Next revision of MusE will have much better jack connectivity which would make
it possible to use it both as midi sequencer and mixer app... but that's in

Keep bugging the developers :)
