The MIDI input settings for Sounds and Groups provide following parameters:
Controls Description
MIDI Section
Active (plug-in mode
only)
Enables the MIDI note input for that Sound/Group (disabled by
default). Please refer to your host documentation to know how to
route MIDI signals to your MASCHINE plug-in. Note that when
Active is disabled for both a Sound and its parent Group, if the
Sound is focused it will receive MIDI notes sent by the host (default
behavior for Sounds).
Source (stand-alone
mode only)
Selects the MIDI port on which the Sound or Group will receive
MIDI notes. Available entries are
None (MIDI note input disabled,
default setting), All (MIDI notes are received on all enabled input
ports), and each enabled MIDI input port. You can enable the
desired MIDI input ports of your MIDI interfaces in the
MIDI page
of the Audio and MIDI Settings panel (see section
↑
2.6.3,
Preferences – MIDI Page ). Note that when None is selected for both
a Sound and its parent Group, if the Sound is focused it will receive
MIDI notes from all MIDI ports and on all MIDI channels.
