Build Status

Launchpad Pro

Open-source firmware for the Novation Launchpad Pro grid controller! This project is based on dvhdr's launchpad-pro project.

This firmware was developed for use with Reason Studio's Reason DAW.

Installing the Firmware

If you can't (or don't want to) build the project from source, you can simply send the launchpad_pro.syx file (in the build directory) to your Launchpad Pro. I use MIDI-OX to send the firmware through, but there are other tools that can do that too.

  1. Turn off your Launchpad Pro
  2. While holding the "Setup" button, turn on your Launchpad Pro
  3. Launch MIDI-OX
  4. Select your Launchpad Pro as an Output device (Options - Midi Devices - Midi Outputs)
  5. Actions - Send - SysEx file
  6. Select the sysex file (launchpad_pro.syx)
  7. Wait for the send to complete
  8. Done!

Installing the Reason Remote Map

For use with Reason, you will also need to install the Remote mapping files:

  • reasonlpp.midicodec
  • reasonlpp.remotemap

On Windows, these are the paths where to install those files:

  • C:\ProgramData\Propellerhead Software\Remote\Codecs\MIDI Codecs\reasonlpp.midicodec
  • C:\ProgramData\Propellerhead Software\Remote\Maps\Other\reasonlpp.remotemap

Usage

For a quick visual example and explanation of this firmware's feature, see the demo video here:

Global Utilities

Global Utils

Modes

Cycle through the modes by pressing the Mode Switch button (labeled User on the LPP). Toggle keyboard/kong note mode by pressing the Note Switch button (labeled Note on the LPP).

MIDI Transport Controls

MIDI transport buttons are defined on the very bottom row.

  • Toggle Loop: Mute button on the LPP
  • Rewind: Solo button on the LPP
  • Fast Forward: Volume button on the LPP
  • Stop: Pan button on the LPP
  • Play: Sends button on the LPP
  • Record: Stop Clip button on the LPP

Velocity Toggle

The bottom-left button (labeled Record Arm on the LPP) toggles between full-velocity and velocity-sensitive modes for MIDI notes sent from the LPP.

Transpose

To transpose the notes sent by the LPP, use the Up and Down buttons (top-left of the LPP).

  • Up: Transpose one full octave up
  • Down: Transpose one full octave down
  • Shift + Up: Transpose one semi-tone up
  • Shift + Down: Transpose one semi-tone down

Track Selection

To switch target tracks in Reason, use the Left and Right buttons (top row of the LPP).

Modes

Notes

This is the default mode for the LPP. In this mode, each square pad is a note.

In "Keyboard" note mode, each color represents one full octave. In "Kong" note mode, each color is a set of 16 MIDI notes, allowing you to set up one combinator with four Kongs, each responding to a set of 16 square buttons.

Kong Note Mode

Kong Note Map

Combinator

In this mode, the left half of the square buttons represents a keyboard (or two Kongs). The right half is used to control the Combinator's rotary and toggle controls.

Combinator Controls

X/Y

In this mode, the full grid represents a two-dimensional control for two CC values.

X/Y Controls

When targeting a Combinator, X is Rotary 1 and Y is Rotary 2.

Mixer

Mixer 14:2

When targeting a Mixer 14:2, the blue buttons represent the first eight channel volumes on the mixer and the green buttons represent the "Solo" toggle for the first eight channels on the mixer.

Line Mixer 6:2

When targetting a Line Mixer 6:2, columns 1-6 of blue buttons represent the first six channel volumes, column 7 controls the main Aux return level, and column 8 controls the master volume on the mixer. The first six green buttons control each channel's "Solo". Green buttons 6 and 7 do nothing.

MIDI Implementation

CC Values

MIDI Transport

MIDI transport uses the following CCs:

  • Play: 16
  • Stop: 10
  • Record: 12
  • Loop: 13
  • Rewind: 15
  • Fast Forward: 14
  • Previous Track: 20
  • Next Track: 21

Combinator Mode

In Combinator mode:

  • Faders (blue pads) control CCs 44 through 47
  • Toggles (green pads) control CCs 54 through 57

Mixer Mode

In Mixer mode:

  • Faders (blue pads) control CCs 40 through 47
  • Toggles (green pads) control CCs 50 through 57

X/Y Mode

In X/Y mode:

  • X controls CC 44
  • Y controls CC 45

Notes

Aftertouch

Each note pad is aftertouch-sensitive, sending MIDI aftertouch based on pad pressure.

Interpolation

Since the fader/rotary controls have a limited resolution, I implemented progressive CC changes where appropriate. This means that moving a fader between 0% and 100% will not happen instantaneously, but smoothly. This avoids unintended glitchy parameter changes.

Rolling Back/Factory Reset

If for whatever reason you want to go back to the original setup of your Launchpad Pro, you can flash the factory firmware by following the instructions here:
