Feeling almost ready to put this out there and into ‘early access’. Pretty happy with the base as it is now. Had to optimize a lot to be able to run mobile HDR(im addicted to bloooom).
Next steps, not in order, are probably:
More songs.
Ability to move/place individual speakers.
Live “DJ effects” to play with, like per track filters, delays, and volume mixing.
Moving/flying/circling/following sound-sources.
Animated ‘musicians’.
Startup/options/?? menu.
Think I’ll need to learn and use proper 3d sliders and levers for effects-interface. Worst case it’ll be 2D hud sliders.
PS new audio-engine(and intro-docs, and the code readability) is amazing, and I’m still just barely using a few features of it 
Gooooo team!
