Logic Pro X – Mapped Instrument

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 in Logic Pro.)
