Pro DJ Link to MIDI

This program lets you connect to Pro DJ Link network and follow the master tempo from DJ players. It converts the signal into MIDI clock signal, so you can use use it to sync synthesizers, external effects and the like to your players.

Note, this program only sends midi clock data, not time code, so you won't get exact beat quantization, just the tempo. Also, as the Node.js is not the best option for hard realtime systems, thus you may see some minor clock drift and jitter. It should be fine for using with effect units, but if very precise sync is important to you, I recommend you keep searching for a better solution.

Installation

npm install -g djlink2midi

On linux systems you may need to install additional packages such as libasound2-dev from your distribution package repositories.

Running

Usage: djlink2midi [options]

Options:
  -V, --version                  output the version number
  -i, --interface <iface>        Network interface to use
  -m, --midi <midi>              Midi interface to use
  -r, --resolution <resolution>  Midi clock resolution (default: 24)
  -h, --help                     output usage information
  -c, --correction <percent>  BPM correction in percent (default: 0)

Run command without options to get the list of interfaces available.

Using on Raspberry Pi

This program can be installed on Raspberry PI if you want a simple portable solution for syncing external effects pedals to your players.

1. Install the package on the system.
2. Add it to startup by adding the command with correct parameters to /etc/rc.local
3. Connect the Raspberry Pi to the Pro DJ Link network using network switch
4. Connect the Raspberry Pi to your effect processor with class compliant USB MIDI interface.
5. Play a track on your CDJ and make sure the "Master" button on CDJ is pressed.

Your effect device should now be able to receive the midi clock and if capable, should be able to keep tempo with your players.
