USB Midi

You can use any generic midi device to remote control the mixer via mixing station.

Supported protocols

  • General Midi
  • Baby HUI Depending on the protocol, the app will automatically assign actions to the device. Take a look at the bottom of the page for the default mappings.

Note: MCU mode is not supported!


Known issues

In Android 5.0 (Lollipop) only the last plugged USB device is working correctly. This is a known bug in Android and cannot be fixed.


  • Full support for usb, bluetooth and network midi devices


A midi device will be represented in the app as one or more input / output devices. In the app you define faders, buttons and knobs (called controller) which then use one of those input/output devices.

Midi overview

  • Midi controller (fader, button, ..)
    • Uses one midi input and output device
    • Has one or more actions assigned which define what parameter should be controlled

Controller types

There are three controller types available:

  • Button: Midi device sends a value when pressed and/or released
  • Fader: Midi device sends an absolute value when fader/knob is moved (e.g. 0-127)
  • Knob: Midi device sends a fixed value for each increment / decrement (e.g. 24 and 27)

Midi Setup

The midi overview can be opened from the mixer via the menu:

Menu -> Setup -> Midi

You can add / edit the midi devices form here.

Add a new device

  1. Press the + item in the menu to add a new device.
  2. Give the device a name, select the appropriate protocol and input / output ports you want to use.
  3. Press Apply

Add a new controller

  1. Select the midi device where you want to add a controller to.
  2. Press the + item in the menu to add a new controller.
  3. Select the controller

Configure a controller

The edit controller view allows you to change the properties of the controller:

  • Unique name: Name which will be shown in the controller overview
  • Input/Output: Selects which USB device should be used for Midi communication

Output Modes

The output mode configures when the value should be send back to the midi device.

Mode Description
On value change Sends midi value when the action value has been changed without a midi input
On midi event+change Sends a midi event when a midi event was received or the action value has been changed
On note up+change Sends a midi event when a "note up" command was received or the action value has been changed

Mapping a midi parameter

In general you can just press the Learn button and move/press the fader/button you want to assign. The app will automatically detect the midi channel and parameter type.

You can also configure the parameters yourself:

  • Event type: The event type defines what midi command the controller should react to

    Event type Description
    Note On/Off Triggers the action on "Note On" and "Note Off" events
    Note On Triggers the actions on "Note On" events
    Note Off Triggers the actions on "Note Off" events
    CC Triggers the actions on "Control Change" events
    Pitch Triggers the actions on "Pitch" events
  • Channel: The midi channel which should be used

  • Param A/B: These two selections are for filtering the midi parameter. Depending on the current selected event type the names of the parameters will change. A value of -1 means that the value will be ignored.
  • Value source: Selects which midi parameter should be used as a value source. Example: A fader sends midi CC events. The position of the fader will be sends as Value of the CC command so this parameter should be used. Select Param B to select the second parameter which is in this case the Value parameter.

    Note: Buttons do not require a value source because the action will be triggered as soon as a matching midi command was received.

Additional button settings

  • Output "on" value: Sets the value that should be send when the button is currently on. Some midi devices can show different colors depending on the midi value so this parameter can be used to change the color.
  • Mode: How the button should react to midi commands

    Mode Description
    Toggle One button press toggles the value
    Momentary Press and hold for a on command. Release for an off command
    Momentary inv. Same as Momentary but inverted

Additional rotary settings

  • Multiplier: Sets the sensitivity of one increment/decrement step
  • Inc value: Midi value for a single increment
  • Dec value: Midi value for a single decrement

Default mappings

The following graphics show the default action assinments for the different modes.

Baby HUI

This driver can be used with the BFC2000 and other HUI capable devices. Make sure the device is set to HUI emulation mode (bhui for BFC2000).
