MIDI

MIDI is an asynchronous serial data protocol that is commonly used in live events.

Receiving MIDI

Setup in the Devices window

Insert a MIDI receirver node and after you have selected a Stream income source, you can enable the Receive checkbox.​

Timecode

If there is any MIDI Timecode coming in, it will be displayed at the bottom of the Data section.

Good to know: Please note you need to use MTC Short Message format for LightAct to be able to parse MTC.

Good to know: in the properties of MIDI Receiver node, you can also apply Timecode offset, which will affect all subsequent operations with this timecode.

Setup in the Layouts window

Place a Read MIDI node and select the MIDI receiver device node whose data you would like to read.

Good to know: In order to watch the output values, you can right-click on the output pins and select Watch.

Controlling Layers with MIDI

Similarly to OSC, it is possible to control layers with MIDI. You can do that through MIDI In window where if you click on Regenerate button, every layer variable that has MIDI flag enabled, will get a unique MIDI Control and Value combination. If the corresponding MIDI message comes in, this variable will be set.

Sending MIDI

Setup in the Devices window

Place a MIDI Sender node in the Device window. After choosing your Stream parameters, such as the Timecode rate and Stream output, you can enable the Send checkbox to activate the node.

Setup in the Layouts window

Place a Send Mtc node and as an input, select the newly created MIDI sender device node.
