CONTROLS

The Pioneer DJM-A9 offers mostly hardware/internal functionality for which you will need to read the Pioneer DJM-A9 manual from https://www.pioneerdj.com/en/support/documents/mixer/djm-a9/

In this manual we will describe only the additional software functionality and options when using VirtualDJ

SOURCE SELECT

Make sure all the Mixer Channels are set to Computer (USB) A or B source (depending on the USB port of the DJM-A9 you used to connect with your computer) in order VirtualDJ to receive and send Audio and MIDI functionalities.

If any of the Mixer Channels are not set to USB A/B source, then VirtualDJ will not be able to send or receive Audio and MIDI from those Channels.

CHANNELS LAYOUT

By default VirtualDJ is using a 3-1-2-4 Channel order.
This means that from left to right the channels are Deck C, Deck A, Deck B and Deck D
A different Mixer Channel Order can be set via VirtualDJ Settings->OPTIONS tab with the MixerOrder setting.

EQUALIZER & STEMS

The Pioneer DJM-A9 is applying its own 3-Band Equalizer, thus VirtualDJ will not apply its internal one. By default the EQ knobs are assigned to fake EQ mode actions, so that they will show their positions on the screen just as a mixing aid.

Using Stems separation via the EQ knobs is possible only when using 2 VirtualDJ Decks (Decks A and B) and the 2 middle Channels. In this case, you can use the outer mixer channels to apply Stems.
