Able MIDI Editor enables you to compose and edit music in MIDI form. The Editor is designed similarly to a Piano Roll, i.e. the time axis is located horizontally, and different positions on the vertical line correspond to different pitches. Multiple Selection lets you select any group of notes and adjust their attributes all at once. Notes are selected according to standard Windows rules; thus it is possible to add notes one-by-one to those already selected, and use the cursor to select a section of the Editing Area. Not only this, the Editor lets you select all notes lying within a defined time or frequency range, by choosing a section of the Time-Ruler or piano keyboard.
