As vkeybd was executed without the --addr parameter, the connection be-

tween the program port and the WaveTable port (or the external MIDI) port can

now be established manually. To do this, select the respective ports and click ‘con-

nect’. To use the command-line tool aconnect, enter aconnect 128:0 73:0

(or the respective ports) to establish a unidirectional connection between the

sender port 128:0 and the receiver port 73:0.

You can now establish a connection between the MIDI port of the keyboard and

the MIDI port of the ALSA sequencer viewer. If you modify keyboard settings,

such as the panning or the pitch wheel (which must ﬁrst be activated under

‘View’), these changes are promptly reﬂected in aseqview.

List the ports available for sending and receiving as well as their connection sta-

tus with aconnect -il or aconnect -ol. Terminate connections established

with aconnect with the option -d, for example, aconnect -d 128:0 129:0.

To terminate all connections, enter aconnect -x. Get information about other

options with man aconnect.

Note

aseqnet can be used to establish MIDI connections over a network.

The program QMidiRoute enables ﬂexible MIDI routing. The MIDI events as

received at the writable MIDI port are presented as one or several maps, from

which they can be selected and transformed into other events. To mention just
