Hi out there,
Well, I'm trying to setup a machine aimed at running softsynths and plugins
(natives synths, LADSPA plugins and jack_fst ones as well).
This is a machine based around a Sound Blaster Live!, with an nforce2 chipset.
I compiled a 2.6.11 kernel with the realtime lsm patch, and everything is
running smoothly, with a very decent latency.
SB Live's MIDI ins and outs are working well when I plug my PC88 in.
Then compiled jack, wine, jack_fst, dssi and such.
Then installed some softsynths RPMS, and a bunch of free VSTis.
Here is my problem :
-jack_fst's plugins respond to after touch in a strange way : they change
presets according to pressure. I recorded some midi to check what was going
on, and Muse and Rosegarden as well are recording plain vanilla after touch,
so I do not understand what's going on...
I checked my Kurzweil's PC88 setup and it is pretty clean, as the MIDI
recording shows (no strange event recorded, except after touch).
I also have a problem with Muse not outputing anything to other jack_fsts than
the first that has been launched, but it may be a problem related to the way
the RPM was prepared. Got to re-compile that one. Rosegarden working very
well out of the RPM-box.
Thanks in advance !

I just checked in a fix in MusE that handles this, somewhat... (will show up
in the next release, hopefully soon)
If I understand things correctly this is actually a problem of jack_fst. If
two instances have the same name it will be impossible for an app like MusE
to know which one is intended for a certain situation, like when loading a
song.

you are seeing a bug in jack_fst.
i did not have a midi keyboard when i developed it, and used vkeybd
which does not do aftertouch.
look in vsti.c and SND_SEQ_EVENT_CHANPRESS:
either find the correct midi code for chanpress or uncomment it
if you find the correct on mail it to me.
and i send you xfst.

It pointed out a difference between aftertouch and
channel pressure I wasn't aware of.
Channel aftertouch/pressure is indeed a "whole keyboard" implementation
of aftertouch (read: cheaper for manufacturers). The less common
polyphonic aftertouch let the player control the aftertouch on a per-key
basis. I've not kept up with the new hardware, perhaps poly AT is more
widely implemented now ?
The MIDI spec includes some other neat stuff, such as the Type 2 MIDI
file format and key-release velocity. Few manufacturers have made use of
that stuff, IIRC.
Best,
