Hi Bill,
Not really a Calf Fluidsynth user but I tried a few of the things you mention. I tried using MusE as host, loading the lv2 version of Calf Fluidsynth with a GM soundfont.
If I create a midi track and click on the pianoroll the synth will respond on the channel set up on the track. At least for the first three channels.
Also tried adding program change to switch between presets and it seems to behave as expected. But this is with LV2, you mention jack, is there a jack version? Have not tried that.
Regards,
Robert

Hi,
Does anyone use Calf FluidSynth?
I have used it for ages now with my home-grown midi sequencer, but have
noticed
odd behaviour just lately.
This is to do with sending Program Change events. My sequence (and the
MIDI protocol)
expect channels to be numbered 0 - 15, though most programs and physical
devices tend
to refer to these as 1 - 16. That's not a problem for me. What is a
problem is Fluidsynth
now seems to be treating 0 - 15 as 2 - 17?
I'm trying to sort out a midi file for a friend - generated by a Windows
Package - and
the file has 4 tracks (not counting track 0) for Violinx3, Viola and
Cello. The midifile
treats these as channels 0 - 3, at least initially. However, Fluidsynth,
which always
starts up with Piano for all channels (except 10) sets channels 2,3,4
and 5 to these
devices. I've got a program to monitor the midi events sent over Jack
and this convinces
me that the Program Change events are specifying the right channels, so
I can only assume
that Fluidsynth is mapping 0 - 3 onto 2 - 5, which sounds like a bug.
As it happens it turns out that when the midifile want to witch to
pizzicato, it switches
to channels 4-7 (5-8 in user terms) but hasn't specified a program for
those channels!
I found the Calf website not very helpful about fluidsynth, and I don't
really want to get
signed up to another email list to discuss bugs in fluidsynth. Just
wondered if anyone
on this list had come across this.
Bill
