decirculator

Visual programming language for sequencing MIDI signals using delay-based circuits.

Blocks

Block	Parameter	Example	Description
Play			Emits signal to all outputs on simulation start or after specified number of bars
	skip-bars	0	number of bars to skip
	signature	4/4	signature of bars to skip
Delay			Emits signal to all outputs after specified delay time after receiving signal at any of inputs
	intervals	1/2,1/4	intervals to use for delay (used one after another, ie first signal is delayed for 1/2, next for 1/4 and so on)
Clock			Emits signal to all outputs at specified intervals
	ticking	true	true if clock is running, toggles to opposite every time clock receives signal at any of inputs
	skip-init	false	if this option is false clock sends initial signal to all outputs straight after simulation start
	intervals	3/8,2/8,3/8	intervals to use for delay (used one after another, ie first signal comes at start, next after 3/8, second after 2/8 and so on)
Counter			Emits signal to all outputs after receiving specified number of input signals
	steps	4	number of input signals to receive before sending signal to outputs
	one-shot	false	true if signals should be sent to outputs only once (per simulation)
	inverse	false	if true counter will emit output signal after every input signal except of every n-th where n = steps
Switch			Emits signal to one output at a time clockwise straight after receiving signal at any of inputs
	side	1	side of output port to send next output signal to (0 = up, 1 = right, 2 = down, 3 = left)
And			Emits signal to all outputs when there are signals at all inputs at the same time
Or			Emits signal to all outputs after receiving signal at any of inputs (like Delay with 0 delay time)
MidiOut			Send midi message with specified parameters after receiving signal at any of inputs
	cc-mode	true	true if midi out should send cc signals instead of note on
	channel	1	number of channel to send midi messages to
	notes	A3,C4,E4,A4	list of notes/signals to send in midi note/cc messages (one at a time, one after another)
	velocities	100,96,127	list of velocities/values to send in midi note/cc messages
	durations	1/16,1/16,1/4	durations of midi notes
