Mapped instruments in the Logic Pro for Mac Environment

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 Sampler, or MIDI channel 10 of a GM-compliant sound module, or a drum machine.

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

• Sent to one of up to 16 output cables (This allows you to create a single instrument that addresses multiple sound sources.)

• Given its own notation parameters: note head shape, relative vertical position in the staff, and drum group assignment (See Use mapped staff styles for drum notation.)

The mapped instrument’s parameters are a subset of the standard instrument parameters. The missing settings are available on a note-by-note basis in the Mapped Instrument window. For details, see Common parameters in the Environment.
