A simple python script i hacked together to allow recording, playback, loop and shuffle of dmx data via OLA on a raspberry pi or compatible linux device.
I made it so i could easily record, trigger and run content to an LED installation, with an autopilot/shuffle function so i didnt have to keep my expensive latop at the event.
Runs great on a raspberry pi 3b+, receiving content VIA artnet from Resolume then sending sacn data to a pixlite 4 to control the LEDs.
It's super hacky as i dont know much about coding, but it works very well and is super responsive. If anyone would like to clean up my code or fork it and make it better then be my guest!
then you should be able to trigger recording, playback, loop and shuffle of the incoming and outgoing artnet/sacn data using Touchosc or any osc application with the following messages:
record - /1/toggle1, /1/toggle2, /1/toggle3 etc
playback - /2/toggle1, /2/toggle2, /2/toggle3 etc
stop all playback - /3/stopallplay
stop all recording - /3/stopallrec
play all recorded files in series on loop - /3/playall
shuffle all recorded files on loop - /3/shuffle
set duration of how long a recording plays before moving onto the next one - /3/loopduration
I have uploaded my templates for Touchosc, The main one has 3 pages, record, playback and control, the other has only playback functionality.
Things to fix:
Make IP address automatic
Make it so loop duration can be changed on the fly (currently you need to stop and start shuffle playback to affect loop duration due to how i have implemented it.
Make it so you can playback multiple recordings at a time, but not so many that it overloads the CPU. ( i have manually ran 6 recordings at once and OLA merges the data nicely, it wouldnt be a difficult addition but would be a nice one and allow layering of DMX data)
Impliment OSC feedback messages so touchosc buttons can change colour when a particular pattern is playing or recording - i think this is possible but havent looked into it yet.
have fun!
