Hi Geoff,
sorry for causing confusion with my typos. Teaches me not to write such
technical posts on the go, without access to a console. Glad you got it
sorted.
When you have it running and some time to spare, it would be very
interesting to get some profiling data from the Pi Zero. To compile
FluidSynth with profiling, you would need to enable it via cmake with:
-Denable-profiling=1
Then start FluidSynth with the General User soundfont (without a MIDI file)
and execute the following commands in the FluidSynth shell:
prof_set_notes 40
prof_set_print 1
prof_start 5 1000
The prof_set_notes number (40 in the above commands) should be chosen so
that the total CPU percentage is below 100% in the profiling output (the
number below "total %"). I always aim for around 85%.
More information about the profiling feature can be found with "help
profile" in the shell and in doc/FluidProfile_0004.pdf.
Cheers,
Marcus
