[LAU] Multiple fluidsynths from command line ?

Hi all, I thought it'd be simple to run many fluidsynths, each from a different console. But it turns out that once one fluidsynth is running, starting another yields: JACK tmpdir identified as [/dev/shm] cannot read response from jack server (No such file or directory) fluidsynth: error: Jack server not running? Failed to create the audio driver The first and second fluidsynths are started the same, with: fluidsynth -m alsa_seq -a jack /usr/local/share/SF/ChoriumRevA.SF2 How is it possible to run multiple instances of fluidsynth ? I'm asking because I use several sounds and I do not want to run one fluidsynth audio output that has trombone and bass into the same Ardour audio input. Thanks, Al
