•
Velocity: Use to set a velocity offset that is added to, or subtracted from, the velocity of the
incoming note. Drag the number vertically to create a velocity offset. You can also click the
specific point on the beam.
To reset all velocity offsets to 0 (no offset), choose Initialize > Output Velocities.
•
Channel: Use to set the MIDI channel of individual notes. This lets you play individual sounds
from different drum sets in the same sound generator. You will normally use the Base setting,
which means that the notes are sent on the channel set in the mapped instrument’s inspector.
If you choose All in the inspector, the channel information of the incoming notes is used. This
is useful if you want to place the mapped instrument after a multi-instrument or standard
instrument in the signal path.
To set all selected notes to Base, choose Initialize > Output Channels.
•
Cabling Mapped Instruments: You can send individual notes from a mapped instrument object
to (up to) 16 different output cables, allowing you to play sounds from different sound sources.
If you select a cable that doesn’t exist, the note won’t be sent out. The Initialize > Output
Cables command resets all cables to #1 (the top outlet of the mapped instrument).
•
Notation Parameters: The last three columns define the notation parameters of
individual notes.
•
Head: Use to change the note head.
•
Rel. Pos.: Use to alter the relative position of the note on the staff. The pitch isn’t altered; only
the vertical positioning of the note head on a staff in the Score Editor. Drag vertically to alter
the note position.
•
Group: As the mapped instrument object is typically used for percussion instruments, click-
holding the Group field opens a pop-up menu of grouped drum families: Kick, Snare, and so
on. MIDI sound modules can have drum sounds mapped across 127 possible notes, which
would result in an interesting staff (to say the least). Assign several related percussion sounds
(tom drums, for example) to the Toms group to place all related sounds on a single staff line.
As with the relative position, the pitch of grouped notes is not affected by grouping them
on a single line.
To neutralize the settings of the Head, Rel. Pos., and Group parameters, choose Initialize >
Score Parameters.
