timout

Conditional branch during p-time depending on elapsed note time.

istrt and idur specify time in seconds. The branch to label will become effective at time istrt, and will remain so for just idur seconds. Note that timout can be reinitialized for multiple activation within a single note (see example under reinit).

Syntax

timout istrt, idur, label

where label is in the same instrument block and is not an expression.

Examples

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