2.2 : MIDI I/O
Settings related to your MIDI input and output devices can be managed from the MIDI group on the
settings page (Fig. 2.2.1).
The list of available MIDI input and output devices will be shown in the main list. You can enable or
disable MIDI I/O devices, and while MIDI devices typically consume little computing power, you may still
nd it useful to disable those that you do not need, as this helps to keep things tidy, and will help you
nd the inputs you need when recording.
To enable or disable a MIDI device, just click on the enable/disable label to the left of the entry.
You can nominate one MIDI output to be the “default MIDI device.” The default output will be used by
the click-track and for MIDI clip previews . To make a different output the default, just click on the make
this the default label.
Add virtual MIDI input...: You can create a clone of a MIDI input such that two inputs both represent-
ing the same physical MIDI input devices, are available on the edit page. For example if your have two
control devices both sharing one MIDI input, or a MIDI control keyboard that supports keyboard zones,
you can duplicate an input and send each copy to a different track in your edit. This can be used to con-
trol two different virtual instruments, or to create layering effects amongst other things.
Show only enabled devices: This option causes disabled input and outputs to be hidden. Enabling
this option can be convenient if your MIDI interface has a large number of inputs and / or outputs, some
of which you rarely use. You will need to uncheck this setting temporarily if you wish to enable devices
that are currently disabled, however.
Middle-C: Unfortunately there is some disagreement in the MIDI world as to which octave should be
used for the C of middle C. If you have a specic preference, or need to work with other software or
hardware where middle C is not considered to be C4, you can change this setting accordingly. Typically
the default C4 is a good choice though.
MIDI popup: This option controls where the piano display should appear when editing MIDI clips. You
can opt to have it appear at the left of the track, or to snap to the left edge of the selected clip.
Send all-controllers-off MIDI message when play stops: This option controls whether Tracktion will
send what is effectively a reset message to MIDI devices when playback stops. Typically this is a good
idea, as it reduces the risk of stuck notes, but some MIDI devices can react strangely to this message.
If you are nding that your MIDI equipment is doing something unexpected when playback stops, try
disabling this option.
