[linux-audio-user] Theatrical sound effects cue player?

Is there a good linux program for playing sound effects cues, in my
case to accompany a theater style performance?

The "ideal" solution would be able to do something like this:

* play samples almost instantaneously when I push the right button
  (some sort of pre-reading the begining?)

* sample length allowed to be arbitrarily long (e.g. music, background
  sounds.)

* multiple samples playable at one time, so you can have background
  sound(s) continue playing while playing another sound --
  e.g. surf/waves sounding in the background, and a ships bell or
  whistle plays over it.

* Probably some different modes for sample playing:
   * On key down, sample plays through to end
   * On key down, sample plays until key up
   * On key down, sample plays until next key down (toggle play/stop)
   * probably something else I haven't thought of.

* Each sample would have individually adjustable volume -- maybe while
  you're playing that background sound, you want to adjust it's level
  w/o affecting any other samples you might play.

* Controlable from the computer keyboard, or an external midi device
  (e.g. my Behringer BCR2000)

* Move through a list of cues, with notes about when each sound should
  happen (e.g. I would type in the line that preceeds the sound...)

The more I write this, the more a midi sampler or drum machine sort of
program seems like it'd be a start, except maybe for the individual
control of sample volume and cue notes.

Anyway, does anyone have any suggestions?

Thanks!
