Device Param

Writes a number into one parameter of the connected audio device every frame - an LFO on a cutoff, a fader on a level.

Output: effect (reaches the device through an Object Selector, or the object graph's owner)

Inputs

Input	Type	Meaning
value	number	the value to write every frame

Parameters

Parameter	Default	Where
key	level	which parameter of the device to write (the keys its Inspector section shows)

Practical example

A Time node (mode sin, rate 5) into Map Range (-1..1 -> 200..2000) into Device Param with key cutoff on a filter pedal: an LFO sweeps the filter, identically on every peer, and nothing crosses the wire - the value already travels as the graph. Values are clamped to the parameter's declared range.

Note

Every peer evaluates its own copy of the graph from the same shared transport and the same replicated pulses, so nothing about the music is sent per frame. See Music Playground.
