Thank you so much for this! I never ever see anyone share open-source setups like this for non-hobby work, and it's inspiring. :)
(Ramble incoming)
I noticed since jumping from windows I'm missing Ableton, and it's been a mental block of knowing that I'll need to choose a new way to do things. It's daft as I loved ardour and LMMS back in 2014, and I'm sure they're even better now :) I totally need to dedicate some time to music, it's been a neglected piece of my soul for a bit too long. :)
Edit: also, Plug Data looks brilliant! I loved MaxMSP, and it got me into game making/coding. :)
