MIDI Editors
Drum Maps
●
To select the same MIDI channel or MIDI device for all sounds in a drum map, click in the
Channel column, press Ctrl/Cmd, and select a channel or output.
●
If you make specific MIDI channel and output settings for all sounds in a drum map, you
can switch between drum maps to send your drum tracks to another MIDI instrument.
Selecting a Drum Map for a Track
●
To select a drum map for a MIDI track, open the Map pop-up menu in the Inspector or in
the Drum Editor and select a drum map.
●
To deactivate the drum map functionality in the Drum Editor, open the Map pop-up menu
in the Inspector or in the Drum Editor and select No Drum Map.
Even if you do not use a drum map, you can still separate sounds by name using a name
list.
NOTE
Initially, the Map pop-up menu only contains GM Map.
I-Notes, O-Notes and Pitches
Going through the following theory helps you make the most out of the drum map concept –
especially if you want to create your own drum maps.
A drum map is a kind of filter that transforms notes according to the settings in the map. It does
this transformation twice; once when it receives an incoming note, that is when you play a note
on your MIDI controller, and once when a note is sent from the program to the MIDI sound
device.
The following example shows a modified drum map with a bass drum sound that has different
pitch, I-note, and O-note values.
I-Notes (Input Notes)
When you play a note on your MIDI instrument, the program looks for this note number among
the I-notes in the drum map. If you play the note A1, the program finds that this is the I-note of
the bass drum sound.
This is where the first transformation happens: the note gets a new note number according to
the pitch setting for the drum sound. In our case, the note is transformed to a C1 note, because
that is the pitch of the bass drum sound. If you record the note, it is recorded as a C1 note.
For example, you can place drum sounds near each other on the keyboard so that they can be
easily played together, move sounds so that the most important sounds can be played from a
short keyboard, play a sound from a black key instead of a white. If you never play your drum
parts from a MIDI controller but draw them in the editor you do not need the I-note setting.
O-Notes (Output Notes)
The next step is the output. This is what happens when you play back the recorded note, or when
the note you play is sent back out to a MIDI instrument in real time (MIDI Thru):
The program checks the drum map and finds the drum sound with the pitch of the note. In our
case, this is a C1 note and the drum sound is the bass drum. Before the note is sent to the MIDI
output, the second transformation takes place: the note number is changed to that of the O-note
for the sound. In our example, the note sent to the MIDI instrument is a B0 note.
