SousaFX-v0.11.6

15 Jul 2026

SousaFX version 0.11.6 is out!

Check out the documentation here: https://rnbo.sousastep.quest/v0.11.6/

Last year at this time I was sorta freaking out about getting everything ready in time for the fests. The raspberry pi rig wasn’t quite working yet, so I had to use my laptop instead, which was a pain. Porting from mac to rpi ended up taking three times as long as I though it would. (due to Hofstadter’s law, I guess) Now, the rig works as intended, and walking around with it is gonna be a good time :)
