timeinsts — Read absolute time in seconds.

Description

Read absolute time, in seconds, since the start of an instance of an instrument.

Syntax

kres timeinsts

Performance

Time in seconds is available with timeinsts. This would return 0.5 after half a second.

timeinsts produces a k-rate variable for output. There are no input parameters.

timeinsts is similar to times except it returns the time since the start of this instance of the instrument.

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