When switching from fluidsynth to jack. fluidsynth will need to
be stopped. Then if fluidsynth was not already using the jack driver
jack would need to be started. Should denemo start the jack server?
Should it start the jack server if the jack on startup is set in
preferences? ....Or should there be a pop up dialog telling the user
that "jack needs to be started in order for jack output to work. Would
you like me to start it for you. If you choose no then you will need
to start it yourself and then click on start/restart jack client in
preferences"
I wrote kind of a flow chart to plan out how we are going to deal with
switching between midi/audio outputs. This is what it looks like:
if portaudio->fluidsynth
if fluidsynth driver == jack
if jackserver_on_startup
startjackserver
startfluidsynth
else
startfluidsynth
if portaudio->jack
if jackserver_on_startup
startjackserver
startdenemojack
if jack->portaudio
stopdenemojack
stopjackserver
if jack->fluidsynth
stopdenemojack
if fluidsynth driver != jack
stopjack
startfluid
if fluidsynth->jack
stop fluidsynth
if fluidsynth driver == jack
startdenemojack?
else
if jackserver_on_startup
startjackserver
startdenemojack
This can probably be reduced somehow in code. Fluidsynth will need to
be stopped in order for portaudio to output sound on many soundcards.
The same is true with jack. On my laptop I would need to stop jack to
do fluidsynth unless the jack driver was used in fluidsynth. So maybe
I should look to see
if (Denemo.prefs.midi_audio_output != variable_going_to_be_assigned){
exit_routines(varaible_in_preferences);
start_up_routines(variable_going_to_be_assigned);
Denemo.prefs.midi_audio_output = variable_going_to_be_assigned;
}
