Following in the steps of our flagship Automation Interface for SSL and Flying Faders, the Tangerine Automation Interface for GML Automation brings the same powerful and intuitive workflow to the GML platform with modern DAW-controlled automation.

The Tangerine Automation Interface for GML Automation is directly built-in to the console without any additional hardware. Each bank of 8 GML faders of will receive an automation motherboard that connects to 8 Tangerine Fader Controllers. These controllers plug directly into the GML faders. Up to 12+ motherboards can be daisy-chained using RJ45 cables. This system replaces all existing GML automation cables and hardware, keeping only the high-quality faders and greatly improving system reliability. The Interface reuses the existing +12V GML power supply when functional and reliable. A single USB cable connects the console to your audio workstation.

Like all our world class interfaces, seamless integration with our state-of-the-art Injektor software and plug-in suite comes standard. Never before could a single mix session cross multiple automation systems until now.  Track your drums on a Flying Faders console in Berlin, finish your vocals on an SSL in London, and then mix on one of the 7 remaining legendary Focusrite console with GML automation; a single Pro Tools session carrying both audio and automation data will seamlessly transition your fader moves and cuts to any Injektor compatible studio, on any console with zero setup time. 

Completely silent and totally fanless, the Tangerine Automation Interface for GML Automation greatly reduces the cost of maintenance of your console. Gone are the days of having to remove faders and fiddle endlessly with TRIM pots to calibrate your automation levels. With the Tangerine system, all calibration is digital and stored on each individual fader controller. Routine calibration can be completed in under 5 minutes, without ever removing a fader.
