Hercules DJControl Inpulse 300

New in version 2.2.4.


This controller is a class compliant USB MIDI and audio device, so it can be used without any special drivers on GNU/Linux, Mac OS X, and Windows. However, if you wish to use the ASIO sound API under Windows, please install the latest driver package available from the Support page.

Sound card setup

This controller has built-in 4 channel output sound card, with MASTER output (RCA) and HEADPHONE output (3.5mm jack).

  • Open Preferences > Sound Hardware

  • Select the Output tab

  • From the Main drop-down menu, select the audio interface, then Channels 1-2

  • From the Headphones drop-down menu, select the audio interface, then Channels 3-4

  • Click Apply to save the changes.

The example setups section provides more details about the audio configuration in Mixxx.


The Master and Headphone knobs, as well as the Master button are hardware controls and interact directly with the integrated sound card’s output. Although they also send MIDI messages, they have NOT been mapped in Mixxx, so do not expect an on-screen reaction when using them. This was done to prevent the knobs to adjust both the gain on the controller’s sound card and in Mixxx.

Mapping description

Controls not included in this mapping

  • Master knob (Hardware control)

  • Headphone knob (Hardware control)

  • Master buttons (Hardware control)

  • Beatmatch guide (Hardware control)

  • PADS: Slicer/Slicer Loop

  • PADS: Toneplay

  • PADS: FX


When using Firmware v1.68 and earlier, each FX pad will send multiple and different Note and CC messages. As these could not all be used properly with Mixxx current effect framework, the pads have not been assigned in this mapping. * However, after applying Firmware v1.72, each FX pad now sends a simple Note On/Note Off (as is the case in every other Pad mode). This would make it easier to use the pads to control effect and the mapping might be modified eventually to take advantage of this possibility.
