Hey there !
Did you know that Aurora can become a really cool Spectral Shepard Tone generator ? 
Without any input connected, press all three buttons (reverse + freeze + shift) for about 10 seconds until the lights go red and white on the module. Then, enjoy !
Congratulations, you won the golden ticket!
To our knowledge, you are the first person to find this Easter egg.
I’m going to DM after this to get your info to send out an official Easter Egg Finder award box.
We’ll be updating the manual with full usage instructions shortly.
Congratulations! So cool you found it!
