The "callback" flag instructs the Pd scheduler to run within callbacks from the audio system; otherwise the audio system might still be opened in callback mode (in portaudio or jack) or not (in alsa or mmio) but if yes, the scheduler and the callback routine communicate via FIFOs... I chose whichever seemed to allow the lowest latency, which depends on the system.

Hi,
just learned that my Pd vanilla Pd-0.45.0 from Miller's Git sources works "much better" (less drop outs, etc) under jack when enabling "use callbacks".
Is there a way to enable this worthy parameter from the command line? Perhaps a way of setting it statically, maybe in s_audio_jack.c ?
Is there any documentation about "enable callbacks" outside of being littered throughout the list?
Two more questions: Isn't Jack's API callback-based? What does it mean to use Jack without enabling callbacks?

Thank you and enjoy! Peter
