Track A

# ~/^ aliases, optional envelope, nested modulation on all 4 parameters

# FM: the carrier is frequency-modulated by another oscillator
~(220 + ~(5,80,0), 0.4, 0) * ^(0, 0.05,1, 3,0.6, 1,0)

# AM/tremolo: the amplitude oscillates over time
~(440, 0.25 + ~(6,0.15,0), 0) * ^(0, 0.05,1, 3,0.5, 1,0)

# deep modulation: freq, amp, phase and pan each have their own oscillator
~(~(3,30,0)+180, ~(2,0.1,0)+0.2, ~(1,1,0), ~(0.5,1,0)) * ^(0, 0.3,1, 4,0.4, 2,0)

# type ~~ for Run, !! for Stop, anywhere in the code

Track B

# a second, independent track: its Run/Stop doesn't touch Track A

# an arpeggio via a for loop inside an overlap
overlap(0.12) {
  for i in 1..4 {
    sin(220*i, 0.2, 0) * env(0, 0.01,1, 0.2,0)
  }
}

# type ~~ for Run, !! for Stop, anywhere in the code
