I'm wondering about the correct way of keeping my application in sync with a timebase master application.
Let's say I have Hydrogen running in master mode and I want to print a message on every 1/4 note Hydrogen is playing.
This is what I would do intuitive (using python):
Code: Select all
client = jack.Client('klicker')
def print_msg (last_tick):
state, pos = client.transport_query()
if state == jack.ROLLING:
if pos['tick'] < last_tick:
last_tick = 0
last_tick = print_msg (last_tick)
So I'm running a loop with very little sleep time and check in every iteration if the current beat is already over.
This seems a little bit dirty and imprecise to me. So what would the right way of solving this problem?
Would be very happy if someone could help
