Question 1

What is MIDI Sketch?

Accepted Answer

MIDI Sketch is a music theory-based MIDI generator that creates complete pop music arrangements. Unlike AI audio generators, it outputs editable MIDI data across nine tracks - drums, bass, chords, arpeggios, melodies and more - that you can import into your DAW and customize with your own sounds and mixing.

Question 2

How is MIDI Sketch different from an AI music generator?

Accepted Answer

AI audio generators produce finished audio that you cannot edit. MIDI Sketch generates MIDI data based on music theory, giving you full control. You can change instruments, edit notes, adjust timing, and mix however you want in your DAW. Same seed always produces the same output - fully reproducible.

Question 3

How do I use MIDI Sketch with my DAW?

Accepted Answer

Generate your song in the browser, then download the MIDI file. Import it directly into any DAW like Ableton Live, FL Studio, Logic Pro, or Cubase. All tracks are separated and ready for your own sounds and mixing.

Question 4

What music styles does MIDI Sketch support?

Accepted Answer

MIDI Sketch includes presets for J-Pop, K-Pop, City Pop, EDM, Ballad, Rock, R&B, and more. Each preset configures appropriate rhythms, chord voicings, and arrangement patterns based on music theory for that style.

Question 5

How are chord progressions generated?

Accepted Answer

MIDI Sketch auto-generates chord progressions based on popular patterns in each genre. Select a style preset and the system creates appropriate progressions with jazz voicings, tensions, and extensions - all grounded in music theory.

Question 6

Is MIDI Sketch output reproducible?

Accepted Answer

Yes, MIDI Sketch is fully deterministic. The same seed and settings always produce exactly the same MIDI output. This makes it perfect for iterative production workflows where you need consistent, predictable results.

Question 7

How is the melody generated?

Accepted Answer

MIDI Sketch generates melodies based on music theory - following chord tones, using appropriate scales, and creating natural phrase structures. You can configure vocal ranges and regenerate with different seeds until you find a melody you like.

Question 8

What tracks are included in the MIDI output?

Accepted Answer

A complete MIDI Sketch export has nine tracks: vocal melody, chords, bass, motif, arpeggio, an auxiliary sub-melody, guitar, drums (kick, snare, hi-hat, fills), and an SE track carrying markers. Each track is on a separate MIDI channel for easy DAW editing.

Question 9

Can I use MIDI Sketch for commercial music production?

Accepted Answer

Yes. The MIDI files you generate are yours to use commercially — as starting points for your productions, demos, or final releases. The engine itself is dual licensed: AGPL-3.0 for open use, or a commercial license for embedding it in closed-source products or proprietary SaaS.

Question 10

Why use MIDI instead of AI-generated audio?

Accepted Answer

MIDI gives you complete creative control. You can change every note, swap instruments, adjust velocities, quantize timing, and mix with your own effects. AI audio is a black box - MIDI is transparent and editable. For serious music production, MIDI is the professional choice.
