Frequently Asked Questions About MIDI Editor
What is a MIDI Editor?
A MIDI Editor is a tool for creating and editing MIDI (Musical Instrument Digital Interface) files. Unlike audio editors that work with recorded sound, MIDI editors work with musical note data - pitch, duration, velocity, and timing - allowing you to compose and arrange music.
What is a Piano Roll?
A piano roll is a visual interface for editing MIDI notes. Notes are displayed as horizontal bars on a grid, with pitch on the vertical axis (like piano keys) and time on the horizontal axis. This makes it easy to see and edit your music visually.
Can I import my existing MIDI files?
Yes, you can import standard MIDI files (.mid) from any source. The editor preserves all track information, instruments, and note data from your original file.
What instruments are available?
The editor includes all 128 General MIDI instruments, organized into categories: Piano, Chromatic Percussion, Organ, Guitar, Bass, Strings, Ensemble, Brass, Reed, Pipe, Synth Lead, Synth Pad, Synth Effects, Ethnic, Percussive, and Sound Effects.
Can I use the exported MIDI in my DAW?
