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. Here is an example of the metro opcode. It uses the file metro.csd Written by &namegabriel;. Example written by &nameandres;. New in Csound 5 (Previously available only on CsoundAV)
