[Denemo-devel] SOC - Some remarks 1

[Ralf Mattes]

Just a few remarks about the SOC branch (this is with denemo
configure flags --enable-jack --enable-fluidsynth --disable-potraudio 
--disable-portmidi).
Denemo was started with 'denemo -M jack -A jack'.

I got some strange cracks/jack xruns after playback when playing back to an 
external app
(aeolus in this case). After some debugging I think that is related to the call 
to
fluidsynth_all_notes_off() in process_audio(). In fact, commenting out that 
call fixes the 
xrun problem. Now, why is fluidsynth called at all even so I don't use it?
Second: the call chain, afaik is:

  process_callback -> process_audio -> fluidsynth_all_notes_off

is this really jack callback safe? 

More in a second post.

 Cheers, RalfD
