Drum Editor

The Drum Editor features a horizontal strip called a Drum Instrument Editor for each instrument used. Every instrument corresponds to a MIDI note (e.g., C3 is a bass drum, E3 is a snare, and B4 is a hihat in General MIDI). The drum instrument's name is shown on the left hand side of the Drum Instrument Editor. The note corresponding to the instrument will be shown if no name is available.
A different instrument can be selected by double clicking the name. New instruments can be added by clicking Add Instr. You can change the order of the instruments by dragging the instrument names (on the left) up or down.
In Add Notes mode, notes can be added by left clicking the mouse. Notes appear in the editor as diamond shapes. The note's velocity is indicated by a small black dot (the higher the dot, the higher the velocity).
In Select Part mode you can select a part of the track by moving the mouse vertically while selecting a part. If the mouse ends on the same instrument where it started, only that instrument is selected. If it ends on a different one, all instruments are selected. The SEL ALL button selects only the instrument if a part of an instrument is selected, it selects all instruments otherwise. You can switch from "one instrument" mode to "all instruments" mode and vice versa by clicking an instrument's name.
If audio is drag-and-dropped from an audio track editor to a drum instrument editor, only beats are detected (no pitch). You can, for example, tap a drum break on the table, record it as audio, and move it to a drum editor.
Selecting similar notes
A menu appears if you right click a note. It has a Select similar notes option, which selects all similar notes in similar bars. "Similar note" means a note at the same position (e.g., at beat 1). "Similar bar" means a bar with the same time signature. You can use this feature to, for example, select all hi-hat hits that are on beat 1 and make them all a bit louder.
If multiple notes are selected, "Select similar notes" will work on the selected notes only. You can, for example, lasso all choruses and then right click a note and use "Select similar notes" to select a particular note within the choruses.
