MIDI In DAT
Summary
The MIDI In DAT logs all MIDI messages coming into TouchDesigner from a specified MIDI device. It outputs columns in a table format - message, type, channel, index, value.
However general setup is simpler. Once you have MIDI set up via the Dialogs -> MIDI Device Mapper, TouchDesigner is ready to receive MIDI via Select CHOPs that point to /local/maps/map1
for device 1, etc.

Parameters - Received Messages Page
Callbacks DAT
callbacks
- Runs this script once for each row added to the table (ie. each MIDI event received). See midiinDAT_Class for usage.
Execute from
executeloc
- ⊞ - Determines the location the script is run from.
- Current Node
current
- The script is executed from the current node location (for example, where 'cc' points to).
- Callbacks DAT
callbacks
- The script is executed from the location of the DAT specified in the Callbacks DAT parameter.
- Specified Operator
op
- The script is executed from the operator specified in the From Operator parameter below.
From Operator
fromop
- The operator whose state change will trigger the DAT to execute its script when Execute from is set to Specified Operator. This operator is also the path that the script will be executed from if the Execute From parameter is set to Specified Operator.
Clamp Output
clamp
- The DAT is limited to 100 messages by default but with Clamp Output, this can be set to anything including unlimited.
