This self-oscillations are awesome and thanks to the uploader! i’ll try your setup soon 
This is my brief test trying a way to find out an answer to the request for a [i]dolphin sonar http://www.elektronauts.com/t/analog-four-the-gift-that-keeps-on-giving/1853/13319/page:1#13319[/i]
Ihope you like it Avantronica, even a tiny bit! 
It needs a bit more of control…i was just searching for a tuning,the dolphin reacted only to certain frequencies 
It’s a one bar-3 trigs-pattern with some performance mode by 3 knobs and 2 tracks, the second being neighbor, also some live played keys, plenty of errors.
But for me something happens!! 
!!! 5 min and more long…!!!
