Metronome in Processing ?

Hi , i want to use a metronome.

Basically to trigger events at the beggining of every 1/4 of a bpm.


Is there any built in function ,or wich library has one ?

Hi Knobs,

check out the Beads library (beadsproject.net). It has a bunch of audio stuff including clocks. If you're not interested in sound there might be an easier option. I'm just doing some shameless self-promotion.

Cheers,

Ollie

if you need a tight clock, i.e. precise timing, have a look at this (toxi's reply): http://processing.org/discourse/yabb2/board_Syntax_3Baction_display_3Bnum_1213599231.html
it works quite well for me, i'm building tiny sequencers and trigger Ableton Live using timed threads and themidibus.

Basically it decouples anything which requires precision timing from the draw() loop where your stuff might be triggered 16-17 ms off from where it should...

Yeah the Beads Clock object is a metronome, taking its timing off the audio signal, which is ultra-precise. Here's an example...
