Arduino sketch to bridge a USB MIDI interface to a remote transmitter which switches a red Recording light.
A simple Ableton control surface to track the state of the recordbutton and send out MIDI CC values to the switch. There are two alternative versions of the control surface, a system version in python, and a user version which is a simple text file.
Any remote transmitter with dry contact input should work. The products in the picture are ITS-2000 and ITWR-3500.
