JackoAudioOut — Sends an audio signal to a Jack port.
Plugin opcode in jacko. 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
Sends an audio signal to an internal Jack audio output port, and in turn to its connected external Jack audio input port.
Note that it is possible to send audio out via Jack to the system audio interface, while at the same time rendering to a regular Csound output soundfile.
ScsoundPortName -- The short name ("portname") of the internal Jack audio output port.
asignal -- Audio to be sent to the external Jack audio input port to which CsoundPortName is connected.
Audio from multiple instances of the opcode sending to the same Jack port is summed before sending.
