All operators

Every character on the grid is a value, an operator or a symbol. Uppercase letters are operators, lowercase letters and digits are values (except v, the arrow going south). Follow a name to its full entry.

Timing and logic

	Name	What it does
C	clock	Counts ticks and writes the count below.
D	beat	Writes a bang * below every N ticks.
S	sequence	Picks the step chosen by its index (left) and writes it below.
R	random	Writes a random number below, every tick.
A	add	Writes a + b below.
J	jump	Copies the cell above to the cell below.
W	wave	Writes a smooth wave (a sine) below: 0 → max → 0, one cycle every rate×4 ticks.
Y	send	Sends the value on its left to the cell dx right, dy down.
I	listen	Listens to a chip channel: writes its volume (0–f) below.
!	tempo	Sets the tempo from the three digits on its right: !150 = 150 BPM.
?	gate	Gate: the operator on its right runs only when a bang touches the gate. Red = it can do nothing there.
@	send	Sends its left value, or a bang, over a named link. Uppercase = shared with the room.
&	receive	Receives from a named link and writes it below.
;	swell	Jumps to its peak on a bang, then falls back: wire it in and things pulse.
,	eye	Looks at one block of the picture and writes its colour, or a bang, below.

Movers and routes

	Name	What it does
E	emitter	Launches a > to its right every N ticks.
>	east	Moves east each tick; becomes a bang when blocked.
<	west	Moves west each tick; becomes a bang when blocked.
^	north	Moves north each tick; becomes a bang when blocked.
v	south	Moves south each tick; becomes a bang when blocked.
:	switch	Sends a mover that reaches it another way: :^ up, :v down, :< left, :> right.
)	turn right	Turns a mover right, from any side, and bangs what touches it. Four of them make a loop.
(	turn left	Turns a mover left, from any side, and bangs what touches it.

Sound chip

	Name	What it does
P	pulse	Pulse voice: plays when a bang touches its left, top or bottom.
G	arpeggio	Arpeggio: a chord on one pulse voice, when banged.
B	triangle	Triangle voice (bass, kick), when banged.
N	noise	Noise voice (hats, snare), when banged.
-	silence	Silences all sound: -14 = 1 beat of silence every 4 beats.

Screen and drawing

	Name	What it does
V	screen	Sets the palette and background, every tick.
F	flash	Flashes the screen when banged.
~	field	Paints the whole back layer with a moving pattern: plasma, stripes, rings…
X	pixel	Draws a 5×5 block at x, y every tick.
H	bar	Draws a horizontal bar every tick.
O	sprite	Draws a mirrored 8×8 creature every tick.
L	line	Draws a line between two points every tick.
Q	ring	Draws a ring (circle) every tick.
U	glitter	Sprinkles random pixels every tick.
"	text	Draws text every tick: x, y, colour, letters.
$	stamp	Draws your own sprite every tick, from the cells below it.
[	layer	The drawing below it goes on this layer: 0 back, 1 middle, 2 front.
]	size	The sprites and text below it are this many times bigger.
T	dissolve	Dissolves random pixels of the drawing every tick, or with a 1 after the amount, fades through the palette.
M	scroll	Scrolls the whole drawing every tick.
Z	mirror	Mirrors the drawing every tick: 0 left→right, 1 top→bottom, 2 both.
K	wipe	Wipes the drawing when banged.
+	zoom	Zooms the whole drawing every tick. A bang gives it a kick.
=	ripple	Slides the rows sideways along a wave. A bang jumps the wave ahead.
%	colours	Shifts every drawn pixel along the palette. Each bang shifts one more.
/	glitch	Throws random bands sideways every tick. A bang gives a burst.

Symbols

	Name	What it does
*	bang	A bang: lives one tick and triggers what it touches.
#	comment	A comment, up to the next # on the line.
_	rail
