I made this a little while ago, I was trying to get it small enough to go in a tweet but just can't get it any smaller. It's like a sweet pipe organ melody.

[0,2,3,5,7,8,10]@=>int n[];Phasor s=>blackhole;TriOsc t=>NRev r=>dac;t.gain(.3);s.freq(2.75);while(1){Std.mtof(n[(s.last()*7)$int]+50+maybe*12)=>t.freq;250::ms=>now;}
