MIDI channel as the Patch draws it, at default values: inlets on the left, outlets on the right.

MIDI channel passes every channel, keeps one channel, or moves everything onto one channel.

What it does#

Mode chooses what happens to channel information. Pass all leaves messages untouched. Only channel drops every message that is not on Channel. Remap to channel rewrites every channel message onto Channel. Channel runs from 1 to 16 and has no effect in Pass all.

When to use it#

Use it to isolate one part of a multi-channel controller, or to label a source with its own channel before merging, or to line a stream up with a MIDI to control node that listens on one channel.

Ports#

Port	Direction	Signal	Lanes
`midi`	Input	MIDI	16 MIDI channels
`midi`	Output	MIDI	16 MIDI channels

Parameters#

Parameter	Label	Range	Default	Unit	Scale	Notes
`mode`	Mode	0 to 2	0		linear	What happens to channel information. Choices: 0 Pass all, 1 Only channel, 2 Remap to channel.
`channel`	Channel	1 to 16	1		linear	The channel kept or assigned.

Mode (`mode`)#

Pass all, Only channel or Remap to channel. A discrete choice.

Channel (`channel`)#

The channel kept or assigned, 1 to 16. Unused in Pass all.

Tips#

Use Only channel to split a controller's zones into separate instruments.
Remap a single-channel source to a different channel so it can be told apart after a merge.

Help patches

Each help patch is an ordinary Toy that teaches one idea. The diagram shows the Patch; the preview shows its Frame. Open it in TuneToys to play and edit it.

Keyboard notes pass through a channel filter before the instrument.

Pass all changes nothing. Only channel keeps messages on Channel and drops the rest.
Remap to channel moves everything onto Channel.
