Greetings:
Not wanting to be left behind by the FST/VST gravy train, I decided
I'd compile and install libfst and jack_fst. Compiling wasn't difficult,
I just followed the instructions, but I had to dig up Torben's advice to
repair aeffctx.h by adding 'struct' to a single line before jack_fst
would build. Btw, I used the sources for libfst 1.5 and jack_fst 1.2,
hopefully those are reasonably up to date, but please let me know if I
need to update. I retrieved the sources from
http://linuxaudiosystems.com/fst/.
Once the VST headers were kosher I built and installed the library and
jack_fst. I fired up jack_fst with the Kontakt demo, made the proper
audio and MIDI port connections, and the plugin responded nicely. My
Absynth plugin died the death, but the SIR reverb plugin worked very
well (I routed the output from XMMS into SIR, thanks to the xmms_jack
output plugin). Great fun.
So I'm getting started with fst and friends. I plan to get the latest
galan now and see how it works with some VST plugins. If I make decent
progress over the next few days I'll try to make time to revise the
tutorial.
Onwards and upwards...
Best,

Hi,
That's great news. Could you mention (either here on in your tutorial)
the wine, glibc, linuxthreads, kernel etc. versions that you use? I'm
trying to debug a segfault that I am seeing with jack_fst.
Thanks

Hi Carl:
Kernel is 2.4.26, Planet CCRMA, low-latency. GCC is 3.2.2, Wine
version is 20031118. VSTserver and vsti are the latest versions from
Kjetil's site (0.3.1 and 0.0.3). Libfst is 1.5, jack_fst is 1.2.
I had a most interesting time last night playing around with various
VSTi plugins. Probably the weirdest thing I did was to run a couple of
plugins (Oberon and PM4) via jack_fst (separate instances) then drive
them with a MIDI sequencer (Sequencer Plus Gold) running under DOSemu.
Very strange to see an MS-DOS MIDI application driving two VSTi plugins
while in Linux. ALSA + JACK + Linux rocks *hard* ! Response from the
plugins was fine, with no latency issues. One thing I noticed: after
some time the plugins stopped responding to attempts to move sliders and
knobs. At that point the plugins had efectively crashed, even though the
sequencer could still drive them (I just couldn't make any changes to
the plugin's settings). This is apparently a known issue. The only
problem I had with stuck notes was when I removed a connection from the
MIDI patch bay while the synth was still sounding. I simply reconnected
the sequencer and the synth, hit the key on my CZ101, and the stuck note
was gone. I had no trouble with stuck notes while playing the plugins
via the sequencer or my Casio keyboard.
Screen redraws are slow on my system (800 MHz Duron), but I suspect
that's due to the low-powered CPU. My video system is running an nVidia
GForce2 with the nVidia driver.
I'll revise the Linux VST/VSTi tutorial this weekend. I'm impressed by
the performance of both fst and vsti, and it's time to update that tutorial.
Serious congratulations to Kjetil, Paul, and Torben !
Best,

Hi Dave,
OK, I'm pretty close to this spec (apart from the kernel version). Can
you give me the output of running /lib/libc.so.6 ?
Thanks

Good grief. I'm now running 2.4.26-ll, GCC 3.2.3 and the same wine, libc,
libfst and jack_fst as you. jack_fst still doesn't work; on 2.4.26-ll it
uses 100% CPU and doesn't do anything.
Does anyone have any ideas on what else might be significant?
Thanks for your help.

Sure thing. Under DOSemu I've run the following applications with
various success:
Sequencer Plus Gold (MIDI sequencer, now available as freeware)
Sideman D/TX synth editor
Drummer rhythm programmer
RAVEL C-like MIDI programming language
Music Printer Plus notation app
Mbox general purpose experimental MIDI environment (very weird
interface)
M/pc starts but doesn't work (mouse problem)
Sound Globs starts but won't produce output
Under Xsteem (an Atari ST emulator) I've run these apps:
Master Tracks Pro sequencer
Cubase sequencer (MIDI-only)
Autobusk
M
Tunesmith
Schoenberg
many others from Tim's Atari MIDI World...
Most of those work well, but some Atari MIDI apps have given me
problems. YMMV, as usual...
And under UAE (an Amiga emulation) I've run a few trackers and synth
editors, such as Octamed and Protracker.
Performance seems best under Xsteem and DOSemu. Depending on environment
settings, performance under DOSemu can be very good. Sequencer Plus
remains my favorite sequencer.
I haven't tried Texture or the old DOS Cakewalk, but if anyone happens
to have them laying around I'd like to see whether they'll run in the
emulated environment.
I've also not got very far with MIDI and sound apps running under WINE,
though there are some notable successes. Obviously realtime performance
is the "gotcha", but it might be possible to tweak WINE for enhanced
audio performance.
Btw, the Linux soundapps pages include a section on emulation software,
with a short list of apps known to run under them.
