Nouns

MIDI Port:

A MIDI port within the MIDI Input Agent is the virtual object within EigenD which corresponds to the operating system's available MIDI ports. These can be browsed using the EigenBrowser - please see example below.

Continuous Controller:

A Continuous Controller within EigenD refers to the object within EigenD used to talk about the incoming MIDI continuous controller values and their associated function. The values associated with them can either be a value between 0 and 127, or you can refer to the controller function by name - a full list of available MIDI CCs can be found here. You can calibrate or invert the incoming values using the examples below, or connect them to Ports within EigenD.

K:

K within EigenD is a virtual object used to refer to an incoming MIDI note number. This is a value between 0 and 127 which corresponds to the desired note number. This value within EigenD can be used to trigger Talker events or connected to other Ports.

Verbs

Choose:

choose

The 'choose' verb is used to select a MIDI port for MIDI input to EigenD from the EigenBrowser.

Invert:

invert

The 'invert' verb is used to invert the sense of the incoming MIDI data.

Minimise:

minimise

The 'minimise' verb is used to calibrate the incoming MIDI data. Set the incoming MIDI device to produce its lowest value before using the 'minimise' verb.

Maximise:

maximise

The 'maximise' verb is used to calibrate the incoming MIDI data. Set the incoming MIDI device to produce its highest value before using the 'maximise' verb.

Examples

Before using the Belcanto examples below, please make sure that you have the desired MIDI Input Agent in the conversation using:

midi	input	X	listen

where X is the number of the desired MIDI Input Agent.

Browsing the MIDI input port

To browse a MIDI input port in the EigenBrowser, making sure you have the EigenBrowser open, use

eigenbrowser	,	midi	input	X	hey

midi	port	browse

where X is the number of the desired MIDI input Agent.

Choosing a MIDI input port from the EigenBrowser

To choose a MIDI input port which is currently selected in the EigenBrowser, making sure you have the EigenBrowser open, use

eigenbrowser	,	midi	input	X	hey

selection	choose

Inverting incoming MIDI data

To invert the sense of incoming MIDI continuous controller data, use

continuous	controller	X	invert

where X refers to the incoming continuous control value.

Set the maximum value of incoming MIDI continuous controller data

To calibrate the upper bound of incoming MIDI, use:

continuous	controller	X	maximise

where X refers to the incoming continuous control value.

Set the minimum value of incoming MIDI continuous controller data

To calibrate the lower bound of incoming MIDI data, use:

continuous	controller	X	minimise

where X refers to the incoming continuous control value.
