Ports#

Before getting into connections, it is necessary to understand some basic information about ports.

Ports are the main building blocks used to route signals throughout Zrythm. A port does not process anything on its own, and is usually part of a processor, like a plugin or track.

2 input ports connected to a processor, which produces output to 2 output ports#

For example, an instrument track has a MIDI input port it uses to read MIDI data from and 2 Audio output ports where it copies the stereo signal after being processed.

Port Directions#

Entrada

The port receives signals

Salida

The port sends signals

Port Types#

Audio

Ports of this type receive or send raw audio signals

Event

Event ports are mainly used for routing MIDI signals

Control

Control ports are user-editable parameters that can also be automated in automation lanes

CV

CV ports handle continuous signals and can be used to modulate control ports

Port Connections#

Ports can be connected with each other, as long as they are of the same type and opposite direction, with the exception of CV ports which may be routed to both CV ports and control ports.

When ports are connected, the signal from the source port is added to the destination port during processing.

Port connection graph for an audio track#

In the above example, the output audio port TP Stereo out L is connected to the input audio port Ch Pre-Fader in L. This connection is created automatically by Zrythm internally.
