ctlout Reference

Transmit MIDI controller messages

ctlout

Description

Transmits MIDI continuous controller values to a MIDI device.

Examples

Letter argument transmits to only one port......... Otherwise, number specifies both port and channel

Arguments

port [symbol]

Optional

Specifies the port (a-z) for transmitting MIDI control messages. If there is no argument, ctlout initially transmits out port a, on channel 1. When a port is specified by a letter argument, channel numbers greater than 16 received in the right inlet will be wrapped around to stay within the 1-16 range.

device [symbol]

Optional

The name of a MIDI output device may be used as the first argument to specify the port. The name 'none' can be used to prevent the object from transmitting MIDI messages on any port.

ctrllr-channel [list]

Optional

Following the (optional) port argument, the next argument is an initial value for the controller number to be used in control messages transmitted by ctlout. Controller numbers are automatically limited between 0 and 127. If there is no controller number specified, the initial controller number is 1.

Following the controller number argument is an initial value for the channel number on which to transmit control messages. If the channel argument is not present, ctlout initially transmits control messages on channel 1. In order for this argument to be used, a controller number argument must precede it.

If a port has been specified with a letter argument, channel numbers greater than 16 will be wrapped around to stay within the 1-16 range. If no port argument is present, the channel number specifies both the port and the channel. The exact meaning of the channel number argument depends on the channel offset specified for each port in the MIDI Setup dialog.

Attributes

matchport [int] (default: 0)

If the port argument doesn't match an existing port or device name, set the object's MIDI port to 'none'.

name [symbol]

Set the object's MIDI port based on a device name. The attribute will attempt to do a case-sensitive partial string match based on the attribute's value.

Common Box Attributes

Messages

int

Arguments

input [int]
In left inlet: The number is used as the control value, and ctlout transmits a MIDI control change message. Numbers are limited between 0 and 127.

  (inlet1)

Arguments

controller [int]
In middle inlet: The number is stored as the controller number of the control change messages transmitted by ctlout. Numbers are limited between 0 and 127.

  (inlet2)

Arguments

channel [int]
In right inlet: The number is stored as the channel number on which to transmit the control messages.

float

Arguments

input [float]
Converted to int.

anything

Arguments

port [list]
Performs the same function as port.

(mouse)

Double-clicking on a ctlout object shows a pop-up menu for choosing a MIDI port or device.

port

Arguments

port [symbol]
In left inlet: The word port, followed by a letter a-z or the name of a MIDI output port or device, specifies the port used to transmit MIDI control messages. The word port is optional and can be omitted. The name 'none' can be used to prevent the object from transmitting MIDI messages on any port.

Output

(MIDI)

There are no outlets. The output is a MIDI control message transmitted directly to the object's MIDI output port.
