touchin Reference

Receive MIDI aftertouch values

touchin

Description

Outputs from MIDI aftertouch (channel pressure) messages received from a MIDI input device.

Examples

Aftertouch messages can be received from everywhere, a specific port, or a specific port and channel

Arguments

port [symbol]

Optional

Specifies the port (a-z) from which to receive incoming aftertouch messages. If there is no argument, touchin receives on all channels from all ports.

device [symbol]

Optional

The name of a MIDI input device may be used as the first argument to specify the port. The name 'all' can be used to enable the reception of MIDI messages from any port. The name 'none' can be used to prevent the object from receiving MIDI messages from any port.

port-channel [list]

A letter and number combination (separated by a space) indicates a port and a specific MIDI channel on which to receive aftertouch messages. Channel numbers greater than 16 will be wrapped around to stay within the 1-16 range.

channel [int]

A number alone can be used in place of a letter and number combination. 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.

anything

Arguments

port [list]
Performs the same function as port without need for the word, "port".

(mouse)

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

(MIDI)

The touchin object receives its input from a MIDI aftertouch message received from a MIDI input device.

port

Arguments

port [symbol]
The word port, followed by a letter a-z or the name of a MIDI input port or device, sets the port from which the object receives incoming pitch bend messages. The word port is optional and may be omitted. The name 'all' can be used to enable the reception of MIDI messages from any port. The name 'none' can be used to prevent the object from receiving MIDI messages from any port.

Output

int

If a specific channel number is included in the argument, there is only one outlet. The output is the incoming aftertouch value, from 0-127, on the specified channel and port.

If there is no channel number specified by the argument, touchin will have a second outlet, on the right, which will output the channel number of the incoming aftertouch message.
