I have managed to
find a free-of-charge Yamaha piano .gig for linuxsampler, which will do
until I can find a good Steinway or Bosendorfer .gig, or an .sf2 host
practical for dynamic live work (sorry, people, but MIDI routers do not make
for on-the-fly changes in live work).
    

PianoTeq: try it, you will probably like it. full JACK support.
awesome application.

I probably would.  But 249€ ?  LinuxSampler will do very nicely.

J.E.B.
