The Log displays errors generated by Ableton Live in red and messages added using the Reactions mapping type in green.

These errors/messages help with the script building process as they are great for finding and debugging issues in MIDI Remote Scripts.
For the Log to function correctly, you must set the correct location of the log.txt file in the Control Surface Studio Settings Menu > log.txt location.
The height of the log can be increased / decreased by clicking and dragging the divider above.
Log watching
Click the Log watching button (eye icon) to turn watching of the log on and off.
If the eye icon of the button is green, that means the application is actively watching the log.

Clear log
Click the clear log button in order to delete the contents of the log.txt.
Log.txt filesize
This displays the current file size of the log.txt file.
As Control Surface Studio continuously monitors the log.txt file, a large log.txt file can impact the performance of the app, so we recommend periodically clearing this using the clear log button.

Errors and messages are displayed in this area.
The number of log entries displayed is defined using the ‘Display last x number of log items’ above.
