pchbend

Get the current pitch-bend value for this channel.

Syntax

ibend pchbend [imin] [, imax]
kbend pchbend [imin] [, imax]

Initialization

imin, imax (optional) -- set minimum and maximum limits on values obtained

Performance

Get the current pitch-bend value for this channel. Note that this access to pitch-bend data is independent of the MIDI pitch, enabling the value here to be used for any arbitrary purpose.

Examples

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