kcps = cpsmidib([irange])

icps cpsmidib [irange]
kcps cpsmidib [irange]

irange (optional) -- the pitch bend range in semitones.

Performance

Get the note number of the current MIDI event, modify it by the current pitch-bend value, and express the result in cycles-per-second units. Available as an i-time value or as a continuous k-rate value.

Examples

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

; For Non-realtime ouput leave only the line below:
; -o cpsmidi.wav -W ;;; for file output any platform
</CsOptions>
<CsInstruments>
