Cabling Directly to a Sub-Channel
To connect the output of an Environment object directly to the input of a sub-channel,
Option-click the source object’s output triangle and choose the sub-channel in the
Reassign Track Object menu. (See
Cabling Environment Objects .)
Note: You cannot drag a cable to a sub-channel. Any dragged cables can only be
connected to the entire multi-instrument object, not one of its sub-channels.
Mapped Instrument Objects
A mapped instrument is particularly useful for drum instruments or any drum-mode MIDI
device. A drum-mode device has different sounds assigned to different MIDI notes, but
only uses a single MIDI channel; for example, a drum kit loaded into the EXS24 mkII, or
MIDI channel 10 of a GM-compliant sound module, or a drum machine.
To create a new mapped instrument
µ
Choose New > Mapped Instrument (or use the New Mapped Instrument key command).
A mapped instrument is used just like a standard instrument, but each individual input
note can be:
• Named (snare, hi-hat, and so on)
• Mapped to an output note
• Given a velocity offset
• Assigned its own MIDI channel
