Midi

You can use any generic midi device to remote control the mixer via Mixing Station.

Supported protocols

• General Midi
• Mackie Control (MCU - recommended)
• X-Touch (in MCU mode, with metering and LCD support)
• X-Touch Expander (in MCU mode, with metering and LCD support)
• Waves FIT (in LV-1 Mode, with LCDs and colors)
• Baby HUI (deprecated)

Known issues

Android

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.

iOS / MacOS

Current iOS (>= 16) / MacOS (>=10.14) versions have a bug in CoreMIDI causing them to not support fast sysex messages. This causes MCU mode not to work correctly (faders moving to random locations). Mixing Station >= 1.9.0 includes a mitigation to this issue by disabling the LCD display and color of the controller to make at least the faders work correctly. Other than that we can only wait for Apple to fix this issue.

If you want to use the old mode, select V1 force sysex or V2 force sysex. Note that this may result in erratic fader movement. Also a hard app restart is required for the changes to be applied.

Default mappings

The MCU and HUI protocols have a default mapping in Mixing Station, making it very easy to get started. The default mapping is shown at the bottom of this page.

MCU

By default, the channels are mapped to the currently active layer in Mixing Station.

Channel strips

Control	Action	Description
SELECT	Select in Mixing Station	-
MUTE	Mute	-
SOLO	Solo/PAFL	-
REC	Not assigned	-
VPOD	Multiple	The knob can control multiple parameters depending on the selected assignment

Buttons

Control	Action	Description
TRACK (Assign-1)	Gain on knobs	-
SEND	Sends 1-8 on knobs	of the selected channel
PAN/SURROUND	Pan on knobs	-
PLUG-IN	Gate on knobs	of the selected channel
EQ	Not yet implemented	-
INSTRUMENT	Dynamics on knobs	of the selected channel
-	-	-
< BANK >	Prev / next layer	-
< CHANNEL >	Scroll current layer	Scrolls 4 channels in the current layer (if more than 8 channels)
F1-F8	Sends on fader	Bus 1-8

Overview

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 controller (fader, button, ..)
  • Uses one midi input and output device
  • Has one or more actions assigned defining the parameter that 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 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 that 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 sent 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 that should be used

• Param A/B: These two selections are for filtering the midi parameter. Depending on the currently 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 sent as Value of the CC command so this parameter should be used. Select Param B to choose the second parameter which in this case is the Value parameter.

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

Additional button settings

• Output "on" value: Sets the value that should be sent 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 an 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
