Description

Generate a metronomic signal to be used in any circumstance an isochronous trigger is needed.

Syntax

ktrig  metro  kfreq [, initphase]

Initialization

initphase - initial phase value (in the 0 to 1 range)

Performance

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.

Examples

Here is an example of the metro opcode. It uses the file metro.csd
