Hi Ebrahim,

thanks for your reply. No, I'm writing my own fluidsynth client and I am not using the supplied drivers; this was just a test.
Incidentally I found a solution for my problem, by calling

fluid_synth_sfload(synth, p->soundfont, 0);

with 0 instead of 1 for the last parameter, program changes in the midi file work as expected.

Hello Victor

About your last point, if you want to use coreaudio as the default sound driver, then you should remove your JackOSX installation.

I am not sure of the precise date but sometime in November 2009, if you look at the archives, I submitted a post with reference to the coreaudio/Jack issue.

Hi everyone,

I've got a little problem here with fluidsynth 1.1.1 and maybe you could shed some light onto it. I am on OSX 10.5.
This is a summary:

1. I am using MIDI files with some program changes at the stat and a GM soundfont. 2. I built a little program to play these using fluid_player_*() functions.
3. None of the program changes are being picked up.

So I had a look at the fluidsynth main program and this is what happens

1. With Jack, I get the same behaviour as above.
2. With coreaudio, it works, ie. all program changes are effected and I get the correct sounds.

Another minor point is that it appears I need to have the Jack server running even when trying to use
the coreaudio driver (with the fluidsynth program).

Any hints or suggestions deeply appreciated.
