XR18 NanoMute midi Foot Controller u
ser’s Manual (
v3.2
)
The NanoMute is an inexpensive and easy to build midi foot-controller designed to interface with the Behringer XR18
digital mixer (ver1.17) via a standard 5pin DIN midi cable. The 1.3
” OLED display provides excellent visibility (even in
sunlight) and provides instant status when any switch is pressed.
The unit allows for 4 to 6 footswitches that can be programmed either as mutes, fader controls (2 settings per channel),
FX tap, or to load XR-18 Snapshots. Each fader/mute switch can simultaneously control up to six XR-18 channels (i.e.
mute all 6 Aux busses at the same time).
When programmed as a
“Mute”, each press of the footswitch will toggle between mute on and mute off. When set as a
“Fader”, each press of the footswitch will toggle between the two programmed (low/high) fader levels. When set for
“Snapshot”, each press of the footswitch will toggle between loading of the two programmed snapshots.
The NanoMute also allows for optional connection of a status led for each switch. These will turn on when:
1) a switch is programmed as a
“Mute” and the status is mute on.
2) a switch is programmed as
“Fader level” and the status is fader high.
3) a switch is programmed as
“FX tap” and is capturing the tap rate.
4) a switch is programmed as
“Snap” and the “B” snapshot is loaded.
The hardware required for the project is available at many online electronic hobby shops and should cost around $25. The
firmware used retains the Arduino bootloader and can be loaded using any 32/64bit Windows PC with a USB port. The
installation software can be deleted once the Nano is flashed, and no additional software is required (i.e. the Arduino IDE).
User switch programming is done right on the NanoMute unit and does not require connection to a PC.
Here are the specs for the parts and how they
’re connected:
