Time to intruduce an instrument API or extend LADSPA ?
Of course one can write a standalone JACK client (currently probably the best
thing to do), but this means reinventing the wheel all over again.
Let see what comes out of LinuxSampler, the discussions and ideas proposed on
the list are quite interesting perhaps it would not be a bad idea to add VST
instrument support so that opensource plugins like that one could be easily
ported without needing and extensive rewrite (at least for the DSP part, the
GUI stuff is a separate issue).
Does anyone remember if it is possibile to use the VST headers (unmodified)
on Linux or is Steinberg against ?
I remember that some time ago Paul Davis wrote about these issues on the
mailing lists but I do not remember what the outcome was.
Thoughts ?

the core code of the plugin has nothing to do with MIDI. thats just a

LADSPA plugin; there are several people on the vst-plugins list who
feel the same way about MIDI in VST ie. that the host should convert
all MIDI data to plugin parameter changes and use a non-MIDI API for
note on/note off etc.
several people on this list feel the same about MIDI in general: it
should not be at the core of any program at all.

You can't use them unmodified because they won't work. You can't
distribute the modifications. You could probably distribute a perl
program that edited them or possibly a diff, but the diff would
contain Steinberg's copyrighted material. They have said they will
accept a patch that makes them work on Linux. I just haven't had time
to gather up my VST stuff and send it to them. Its not hard.

ardour will bind any MIDI CC to any LADSPA parameter. it also maps
NoteOn/NoteOff to any LADSPA parameter, with the intent that it be
used to drive a switch. result: LADSPA has no clue about MIDI, but any
LADSPA plugin running inside ardour can be "completely controlled"
from MIDI.
you probably don't want to run amsynth in ardour, though.
ecamegapedal is more like the right kind of thing, but in truth i
think it would be a great project for someone to cook up something
like ecamegapedal that was oriented toward sound generating plugins,
rather than FX plugins. steinberg just released a realtime VST host
specifically to host VSTi's (instruments); ecamegapedal is cool, but a
JACK-ified LADSPA instrument host would be better yet.

Well i was working on this type of host program, but for the plugin spec
im now using in amsynth. Obviously if LADSPA is really feasible for this
kind of thing, i'd want to get that working..

i should have mentioned that pitch is handled as well, yes.

Spiral Synth Modular? It doesn't make dleaing with LADSPA plugins as easy
as it could, but its going to get easier (aparently).
