Receive MIDI aftertouch values

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.

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.

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.

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.
