Description

Plugin opcode in py. This opcode is part of the plugin repository and has to be installed separately. The plugin repository can be found here: https://github.com/csound/plugins

These opcodes evaluate a generic Python expression and store the result in a Csound variable at k-time or i-time (i suffix).

The expression must evaluate in a float or an object that can be cast to a float.

They can be used effectively to trasfer data from a Python object into a Csound variable.

Example of the pyeval Opcode Group

The code:

k1           pyeval      "v1"

will copy the content of the Python variable v1 into the Csound variable k1 at each k-time.
