bass mid treb midioff

speed 1.00

Variables and functions

time, frame, dt: seconds since start (scaled by speed), frame count, seconds per frame
bass, mid, treb: audio bands: about 1 at a steady level, up to 4 on hits, 0 with no audio
bass_att, mid_att, treb_att, vol: smoothed bands, and the average of the three
note, vel, onset, held: last MIDI note and velocity (0–1); onset jumps to 1 on each note and fades; notes held
cc1 – cc16: MIDI controller values (0–1)
track, trackpos, newtrack, lanes: seconds into the newest track, how far through it (0–1), a pulse that jumps to 1 when any track starts and fades, lanes playing
i, n, aspect: plane number (0 MilkDrop A, 1 Stream, 2 MilkDrop B, 3 Nested), plane count, screen width ÷ height
q1 – q8: set in the Camera block, readable in every plane
plane outputs: x y z position · rx ry rz rotation in radians · sx sy scale (sz follows them unless set) · a opacity · add 1 for additive glow · bright gain
solid outputs: depth: 0 a flat screen, 0.9 about a cube · round: 0 a box, 1 a sphere · relief: the picture’s brightness pushes the surface out (0.1 gentle, 0.5 strong, negative carves in)
camera outputs: cx cy cz position · tx ty tz target · fov in degrees · roll · fit distance multiplier · zoom, rot, decay for trails (decay 0 turns them off)
background outputs: set in the Camera block: bg brightness (1 = the level slider, 0 hides it) · bgzoom · bgrot in radians · bgx bgy pan
complex time: tim is the imaginary part of the clock (time is the real part) · theta, set in the Camera block, turns the clock: 0 forward, pi backward, pi/2 imaginary
plane source: src = 0 its own picture · 1 4D fractal dive · 2 Lorenz in complex time · 3 flow field · 4 oscilloscope w x y z · 5–8 w, x, y or z alone · 9 MilkDrop A · 10 Stream · 11 MilkDrop B · 12 Nested
4D fractal: set in the Camera block: jphi slice in radians (0 Mandelbrot, pi/2 Julia) · jcr jci the Julia c · jdive octaves per second · jtwist slice turn per unit of tim · jmax deepest octave · input jdepth
other add-ins: Camera block: lspan Lorenz window · lflow how fast its start point moves · fsel flow field 0–3 · osys oscilloscope system 0–2 · orate its speed · inputs owr owi oxr oxi oyr oyi ozr ozi (−1 to 1) and oblow, a pulse when it meets a singularity
functions: sin cos tan asin acos atan atan2 abs sqrt sqr pow exp log log10 floor ceil int min max sign clamp mix fract tri noise rand frand above below equal band bor bnot if(test, a, b)
