Hello All,
In my proof of concept, I have the following code:
/* callback of the sequencer */
void sequencer_callback(unsigned int time, fluid_event_t* ev,
fluid_sequencer_t* seq, void* pdata) {
printf("%d\n", fluid_sequencer_get_tick(seq));
fluid_sequencer_set_time_scale(seq, 500.0); // 500 ticks per second -
i.e.: slow down
printf("time-scale changed!\n");
printf("%d\n", fluid_sequencer_get_tick(seq));
}
The sequencer runs at the default 1000 ticks/s (of rendered sound-output), and
in the call-back I scheduled at 2400 ticks, I change the time-scale
(representing a tempo change in the music)
The output here is:
2400
time-scale changed!
1200
It looks like that when the I change the time-scale that this also impacts the
current tick of the sequencer.
Is there a way around this?
This may be relevant: fluid_sequencer_set_time_scale causes timing problems ·
