how to set player as 'on_air'

[gb160]

Hi , great project btw.
Im using a modified monitor-curses.py and wondering if it's possible to set the players 'on_air' status.
Im monitoring my mixer 'DJM-450' with receivemidi in my modified script so I can easily tell if a player has its fader up or not (DJM-450 has no ProDJ Link).

My understanding is the XDJ 1000 will show some sort of on-air status on the display if the 'on_air' status is set.

I implemented just such a feature as an integration example for a Beat Link Trigger user for the Xone:96 mixer. You can see how to do that with Beat Link Trigger here and you would just need to adjust the MIDI values to match the DJM-450.

Hi mate, thanks for this. I've only just discovered Beat Link Trigger and it looks very interesting. I'll be having a good look over what it can do.

If I have any questions, (and there will be questions ;) ) I'll pester you over there!

Thanks again.

@brunchboy Well I have it working with my DJM-450, I just needed to set the mixer name, set the 450 to use midi channel 16, and for some reason the 450 uses values 17 and 18 for faders 1 and 2....so I changed those values and everything worked as expected.

Although BLT seems a great project I can't help but feel its overkill for what I need.

Im really happy with my modified script and the on air status was just a little idea that I'd like to implement in my current script with python-prodj-link if possible.

Thanks again though, at least I know its definitely achievable.

If you want to stick with python-prodj-link, I would start with modifying vcdj.py. Add support for sending BeatPackets with "type_mixer" and your channel on air information, similar to fader start:

python-prodj-link/prodj/core/vcdj.py

Line 109 in 16d7065

def command_fader_start(self, player_commands):

It's definitely useful to peek at James' code, I have not tried to send mixer beat packets yet. Could be missing something. If you got it working, feel free to send a pull request. I have very limited time lately, but will do my best to look into it.

It makes sense indeed to work in the environment that most suits your needs, which is why I created my detailed, platform-neutral documentation of the network packets and file formats. Note that channels-on-air is not a beat packet, it is its own kind of packet. I document it here: https://djl-analysis.deepsymmetry.org/djl-analysis/mixer_integration.html#channels-on-air

[brunchboy]

Beat packets are one of seven different kinds of packets that get broadcast on port 50001. The full list is here: https://djl-analysis.deepsymmetry.org/djl-analysis/packets.html#_port_50001_packets

@brunchboy This is excellent info mate. Although implementing it here might be 'above my pay grade' I'll be taking a good look when I get some time and seeing if I can get anywhere.
Thanks.
