metro metro metro Trigger Metronome Generate a metronomic signal to be used in any circumstance an isochronous trigger is needed. ktrig metro kfreq [, initphase] initphase - initial phase value (in the 0 to 1 range) ktrig - output trigger signal kfreq - frequency of trigger bangs in cps metro is a simple opcode that outputs a sequence of isochronous bangs (that is 1 values) each 1/kfreq seconds. Trigger signals can be used in any circumstance, mainly to temporize realtime algorithmic compositional structures. metro will produce a trigger signal of 1 when its phase is exactly 0 or 1. If you want to skip the initial trigger, use a very small value like 0.00000001. Here is an example of the metro opcode. It uses the file metro.csd Written by &namegabriel;.
