Pro Tools Setup and Troubleshooting: Impact LX+

Impact Setup & Troubleshooting

First you will need to set the Impact LX+ keyboard to USB Port Setup Mode 3:
  1. Hold ‘Shift/Mute’ and press ‘Patch > (Setup)’. The display will say ‘S.E.t.’
  2. Press key A2. The display will say ‘0.0.0.’ or ‘0.0.2.’
    • LX25/49/61+: A2 is the 13th white key from the left.
    • LX88+: A2 is the 22nd white key from the left.
  3. If you are using LX49/61/88+ continue to step 4. For LX25+ see below.
  4. Press key C3 on LX+ (labeled with a ‘-‘) (C1 on the LX25+) until the display says ‘0.0.3.’
  5. Hold ‘Shift/Mute’ and press the ‘Patch > (Setup)’ button to exit Setup Mode.
If you are using an LX25+ continue from here:
  1. Press key C3 (labeled ‘Enter).
  2. Press key C1 on the LX25+ (labeled with a ‘-‘) until the display says ‘0.0.3.’
  3. Hold ‘Shift/Mute’ and press the ‘Patch > (Setup)’ button to exit Setup Mode.
Now it’s time to launch Pro Tools. With Pro Tools open go to the ‘Setup’ menu and select ‘Peripherals’, as shown in Image 1. In the Peripherals menu, go to the ‘MIDI Controllers’ tab, then configure the following settings:
  • Type: ‘M-Audio Keyboard’
  • Receive From: ‘Impact LX+ MIDI2’ in OSX ‘MIDIIN2 (IMPACT LX+) [Emulated]’ in Windows
  • Send To: ‘Impact LX+ MIDI1’ in OSX ‘IMPACT LX+ [Emulated]’ in Windows.
  • Click ‘OK’.
If everything is configured correctly, you should see the Impact LX+’s MIDI ports configured as shown in Image 2 for Windows and Image 3 for OS X. Now your Impact LX+ is configured in Pro Tools.


Transport Buttons The Impact LX+’s transport buttons perform the following functions:

LoopUsed in conjunction with other buttons to activate loop functions
>>Fast Forward

PlayStart playback
RecordArm the transport for recording

The ‘Loop’ button provides additional options and gives access to the following functions:

Loop + PlayLoop Playback
Loop + RecordLoop Record
Loop + StopUndo
Loop + RWGo to start
Loop + FFGo to end

Note: The loop button has no function when pressed by itself.

Mixer Mode Functions

  • Faders 1-8 = Channel Volume for the selected bank
  • Fader 9 = Master Volume
  • Buttons 1-8 = Mute, Solo or Record Arm
  • Button 9 = Select function for buttons 1-8
  • Pots 1-8 = Assignable

Controlling Instrument Parameters It’s possible to assign the Impact LX+’s control pots to instrument parameters in Pro Tools. Many of the AIR instruments and third-part plug-ins have a ‘Learn’ function.

For example, if you right-click on a parameter in the ‘XPand 2’ plug-in you will see menu with assignment options, as shown in Image 4. Select ‘Learn CC’ then move a control pot on your Impact LX+ keyboard. That parameter should now be controlled by the pot.


If you encounter the warning shown in Image 5, it is because the Impact series keyboards are not M-Audio keyboards. Simply click the ‘Don’t show this again’ option and then click ‘OK’.
