Do you need this? If it is streamed straight from the hdd then it may be 
more efficient to use ardour or some other sample editor/sequencer which 
has already been written.

Essential for interacting with midi instruments.

Can't muse or rosegarden do this already?

Ls has Jack support. It's fairly simple to add a new jack i/o.

Sounds like an organ players wet dream ;)

I add this

As interfacing with Linux sampler is a matter of adding a few ascii 
calls to your app it appears to be a relatively straight forward process 
to add support to any one of the sequencers that are available. What's 
the catch?

I'm trying to figure out the difference here between what 
ardour/muse/rosegarden do now and what Linux sampler is capable of. 
Anyone have more clues?

 From the advertising on the gigasampler site I get the impression that 
the sequencing and recording interfaces are mainly to provide an all in 
one app. Give the consumer something worth spending a large sum of money 
on. Probably also the proprietry market expects it.

BTW I noticed Paul Davis did some work on adding midi tracks to ardour

Apparently upon the beginning of the barrage, the donkey broke 
discipline and panicked, toppling the cart. At that point, the rockets 
disconnected from the timer, leaving them strewn around the street. 
Tethered to the now toppled cart, the donkey was unable to escape before 
the arrival of U.S. troops.
