With a custom remote script, no manual mapping is necessary! Simply select any device and have it's parameters mapped to your Cenx4.
Everything about the Cenx4 is open source. The firmware, hardware, web control/update application and Ableton remote script. Want a new feature? If you're comfortable with coding, you can do anything you want.
Cenx4 uses standard MIDI over USB. No need for any special drivers. Encoders transmit standard MIDI CC messages and the OLED displays are controlled via SysEx messages.
