Create a Lane Set for a GM drum kit
General MIDI has an established keyboard assignment pattern (a MIDI note map) for drum and
percussion sounds. This mapping standard is often followed in non-GM, GS, or XG compliant
sound modules, samplers, and synthesizers. In some cases, however, you will need to make a
few changes.
As the Step Editor is ideally suited for creating and editing drum kits, you may want to create a
Lane Set that is specifically tailored for your drum sets, including the correct drum names and
hi-hat modes.
m
Choose Lanes > New Lane Set for GM Drums from the Step Editor menu bar (or use the Lane Set
pop-up menu, or corresponding key command).
You can change the names, positioning, and hi-hat modes of each drum or percussion lane in
the Lane Set. See
on page 436, for information on renaming each drum
sound in your kit, if it doesn’t match the GM mapping standard.
Define a hi-hat group
In hi-hat mode, lanes can be grouped together. Only one event from grouped lanes can be
played at any ruler position. This function is typically used to prevent different hi-hat notes (open,
closed, pedal) from being inserted at the same time position. This mirrors the real-world behavior
of hi-hats, which can’t be simultaneously opened and closed.
1
Click the dot shown to the left of a lane name (Open HH, for example).
2
Click the dot shown to the left of other (vertically adjacent) lane names (Ped HH, for example).
A dotted line links the two lanes in the left edge of the column.
3
Click the dots of each lane to turn off hi-hat mode.
All lanes in a hi-hat group must be vertically adjacent to each other. To group several events in
nonadjacent lanes, move the lanes by dragging the names up or down the Step Editor window.
If you add an event to any lane in a hi-hat group, all existing events at this time position are
deleted.
You can create as many hi-hat groups as needed in a Lane Set, but each group must be
separated by at least one lane that does not belong to a hi-hat group.
Rename a Lane Set
m
Choose Rename Lane Set in the Lane Set pop-up menu. Enter a new name, then press Return.
