Receive MIDI aftertouch values Outputs from MIDI aftertouch (channel pressure) messages received from a MIDI input device. Cycling '74 Max MIDI port Message Sets MIDI Input Port/Device TEXT_HERE TEXT_HERE After Touch TEXT_HERE MIDI Channel TEXT_HERE MIDI port ID 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. MIDI output device The name of a MIDI input device may be used as the first argument to specify the port. MIDI port and channel 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. Extended MIDI channel 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. Set the MIDI input device Performs the same function as port without need for the word, "port". Select a MIDI input device Double-clicking on a polyin object shows a pop-up menu for choosing a MIDI port or device. Output received MIDI aftertouch messages The touchin object receives its input from a MIDI aftertouch message received from a MIDI input device. Set the MIDI input device 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. Port Name 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. 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.
