reached via the Input and Output Channel choosers' Congure... option. Note that
the Audio Preferences also provide access to the Channel Conguration dialogs, which
determine which inputs and outputs are used, and whether they are available to Live as
mono or stereo pairs. Essentially, the Channel Conguration dialog tells Live what it needs
to know about how the computer is connected to the other audio components in your
studio.
13.2.1 Mono/Stereo Conversions
When a mono signal is chosen as an audio track's input, the track will record mono samples;
otherwise it will record stereo samples. Signals in the track's device chain are always stereo,
even when the track's input is mono or when the track plays mono samples.
Mono is turned into stereo simply by using the identical signal for left and right channels.
When a track is routed into a mono output, the left and right signals are added together
and attenuated by 6 dB to avoid clipping.
13.3 Exter nal MIDI In/Out
MIDI from the outside world is routed into Live just like audio. From the Input Type chooser
of a MIDI track, you can either select a specic MIDI input port or All Ins, which is the
merged input of all external MIDI ports. The Input Channel chooser offers the individual
input channels of the selected MIDI port and the merged signal of all channels, All. As is
the case with audio inputs, the Input Channel chooser also has meters next to every entry
to represent activity on the respective input channel. If multiple MIDI tracks are selected,
any changes you make to these choosers will be applied to all selected tracks.
