stdout/stderr from stuff launched from the window manager usually shows up in ~/.xsession-errors for me.

I use the ion3 window manager, but others probably have some way of capturing printfs from programs it launches.

I specifically launch jackd with  > /tmp/jackd.errors 2>&1 &, so I have some record of what xran or got booted, and when (/tmp is tmpfs).

I've run PHASEX for many hours without any problems. 

I can however cause fluidsynth to die and exit, by running a very large multi-sampled Steinway piano soundfont, holding the sustain pedal down, and then playing a couple chords repetitively (i.e. Tony Banks at the intro of "Lamb Lies Down on Broadway") for 20-30 seconds at randomly-varying velocities. It's a CPU-intensive operation... perhaps your PHASEX patch is chewing up a lot of cycles.
