MIDI in Sequoia
MIDI is a standardized command language that helps to control synthesizers.
In addition to the command to play a note (NoteOn, Note Off), there are control commands (Control Change) for internal synthesizer parameters (volume, panorama, the piano pedal, filter settings and others), program change commands (Program Change) to open saved sound programs and for other tasks. These commands are called MIDI events. A MIDI object contains a series of events and the times at which they occur.
Similar to audio objects, MIDI data is represented in Sequoia in the form of MIDI objects.
MIDI objects do not contain audio data. They are used to control synthesizers that then create corresponding sounds. They are comparable to music notation that is about to be played by a musician.
You can create MIDI objects by loading MIDI files, recording received MIDI data from a MIDI keyboard, or creating an empty MIDI object and drawing in the notes in the MIDI Editor.
