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 and 2 Audio output ports where it copies the stereo signal after being processed.

Port Directions

Input

The port receives signals

Output

The port sends signals

Port Types

音频

Ports of this type receive or send raw audio signals

Event

Event ports are mainly used for routing MIDI signals

控制室

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

端口连接

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.
