AI Music Generators that create DAW-ready MIDI ideas fast
Orb Producer Suite (Hexachords) is an AI-assisted composition plugin and standalone tool that generates chord progressions, basslines, melodies and arpeggios as MIDI for DAWs. Ideal for producers and composers who need theory-aware musical ideas without programming music theory, it offers a trial and paid licenses (approx. one-time and tiered pricing). It excels at MIDI export and DAW integration but is not a sample-based generator or full audio instrument.
Orb Producer Suite (Hexachords) is an AI Music Generators plugin and standalone app that produces chord progressions, basslines, melodies and arpeggios as editable MIDI. The suite focuses on music-theory-aware generation rather than sample synthesis, letting users lock scales, voicings and rhythmic patterns. Its primary capability is rapid idea generation with configurable harmonic engines and drag-and-drop MIDI export to any DAW. The key differentiator is its modular Tracks (Chord, Bass, Melody, Arp) designed for arrangement-level control, serving producers, songwriters and game composers. Pricing is accessible with a free trial and mid-range paid licenses (approximate price tiers).
Orb Producer Suite from Hexachords is a collection of music-generation tools delivered as VST3/AU/AAX plugins and a standalone application designed to speed songwriting and arrangement. Originating from Hexachords (a small music software company), Orb positions itself as a composition assistant that encodes harmony and melodic heuristics into user-controllable modules. Rather than generating audio, Orb outputs MIDI and patterns tailored to scales, chord voicings and rhythmic grooves, so it plugs directly into producers’ existing instrument chains. The suite’s value proposition is to shorten idea-to-prototype time: generate harmonies, audition voicings, then drag MIDI into your DAW for immediate refinement.
At the feature level Orb Producer Suite provides multiple dedicated tracks: Chords, Melody, Bass and Arp. The Chord track can create progressions constrained to keys, with voicing depth and inversion controls; progression variants can be generated and auditioned in-context. The Melody track produces note sequences that follow selected scales and rhythmic templates, and you can set complexity/sparseness parameters. The Bass track gives root-note and pattern options with octave/lock settings for tight low-end. The Arpeggio module converts chords into synced arpeggios with gate, pattern length, and direction controls. All tracks export MIDI via drag-and-drop or direct MIDI routing, and the plugin syncs to host tempo, making arrangement and layering straightforward.
Pricing for Orb Producer Suite generally comes as a trial plus paid licenses; Hexachords offers a free trial/demo download (time- or feature-limited) and paid license tiers. Paid options have historically been one-time license purchases or occasional sales — typical prices reported are in the mid-hundreds of euros/dollars for the full suite (approximate). Hexachords also provides upgrade paths for existing Orb users when major versions release, and educational discounts are sometimes available. There is no monthly subscription widely documented for the core Orb Producer Suite; enterprise or bulk licensing is handled via direct contact with Hexachords for teams or academic deployments.
Who uses Orb Producer Suite in real workflows? Electronic producers use it to generate 8–16 bar chord and bass foundations they export as MIDI to Ableton Live for arrangement; film/game composers use it to quickly sketch harmonic ideas and hand off MIDI to orchestral VSTs. Specifically, a music producer uses Orb to create 8-bar chord/melody sketches in under five minutes to speed an EP workflow, and a game audio designer uses Orb to generate multiple harmonic variations for adaptive music layers. Compared to a sample-based loop library, Orb is focused on MIDI generation and compositional control rather than finished audio loops, putting it in direct comparison with tools like Captain Plugins and Scaler.

Copy these into Orb Producer Suite (Hexachords) as-is. Each targets a different high-value workflow.
Role: You are Orb Producer Suite; generate a clean 8-bar chord progression suitable for a pop ballad. Constraints: Key C major, 90 BPM, 4/4, 8 bars total, primarily triads with optional 7th chords on bars 4 and 8, voicings between C3 and C5, simple rhythm (one chord per bar or two chords per bar max). Lock the scale to C major and quantize to 1/8. Output format: Provide a labeled chord list by bar number with chord symbol, MIDI root note and octave, explicit voicing notes (e.g., C3 E3 G3), suggested inversion, and a suggested export filename. Example first two bars: Bar1: Cmaj - C3 E3 G3; Bar2: Am - A3 C4 E4.
Role: You are Orb Producer Suite; write a 4-bar melodic hook over the provided chords. Constraints: Key G minor, 100 BPM, 4/4, melodic range D4–D5, max 8 notes per bar, use only scale tones (no chromatic passing unless explicitly marked), emphasize strong beats (1 and 3) and include one optional grace/lead-in. Input chords (example): | Gm | Eb | Bb | F |. Output format: Provide a per-bar MIDI-style step list (note name + octave, duration grid like 1/8 or 1/4, velocity 0–127), a concise human-readable lyric-like phrase, and a one-bar alternate ending. Example: Bar1: D4 q v100, F4 q v90; Bar2: Bb4 h v100.
Role: You are Orb Producer Suite; produce an 8-bar bassline tailored for an EDM/house track. Constraints: BPM 125, key A minor, 4/4, syncopated groove, note range A1–A2, include exactly two rests per four-bar phrase, lock to A natural minor scale. Output format: Provide a bar-by-bar MIDI pattern with note name+octave, duration (1/16,1/8,1/4), accent markers (e.g., '>'), suggested velocities per note, portamento/slide flags where appropriate, and a short processing suggestion (sidechain rhythm, saturation). Include an example pattern for Bar1, and a recommended export filename like Bassline_Aminor_125.mid.
Role: You are Orb Producer Suite; create six distinct 8-bar harmonic variations derived from a seed progression for looping adaptive music. Constraints: Seed progression: | Am | F | C | G |; each variation must keep recognizable root motion but change mode, harmonic rhythm, added tensions, or reharmonization; voicings must sit within C3–C5 and be loop-friendly. Output format: Provide a numbered list 1–6 with variation name, full chord-by-bar sequence, voicing notes for bar1 and bar8, suggested track exports (e.g., Chord_stem.mid, Pad_stem.mid), and loop-length label (8 bars). Example: Variation 1 - Modal Shift: | Am | Fmaj7 | C | Gsus4 | ...
Role: You are an experienced game composer using Orb Producer Suite; produce a base 8-bar progression and derive four loop-ready adaptive stems for engine-ready layering. Multi-step: 1) Provide base progression in D minor at 90 BPM. 2) Create four stems—Ambient Pad (sustained voicings, slow movement), Rhythmic Arp (1/16 or 1/8 grid), Low Bass (groove locked to kick), Lead Motif (short hook). Constraints: all stems loop at 8 bars, registers must not clash, transitions must be safe (no abrupt pitch jumps), and include suggested crossfade durations. Output format: For each stem give MIDI clip name, bar-by-bar note sequences, voicing notes (pad), arp pattern grid, bass MIDI, lead motif, recommended crossfade times and DAW export filenames. Example snippet: 'Pad_stem.mid: Bar1: D3 F3 A3 (whole)'.
Role: You are a senior music theorist using Orb Producer Suite; develop four 8-bar melodic variations that evolve a two-bar motif using first-species counterpoint and modal interchange. Constraints: Key E Phrygian, tempo 72 BPM, instruments: Flute (melody) and Cello (counterpoint), flute range E4–A5, cello C2–C4, avoid parallel fifths/octaves, maintain smooth voice-leading and allow modal interchange on bars 3–4. Output format: For each variation provide the motif statement, bar-by-bar MIDI note lists for flute and cello, voice-leading annotation explaining avoided intervals, suggested harmony/voicings for a supporting track, and two short examples showing transformation techniques (sequence, inversion). Example: 'Variation A Bar1: Flute E5 q, D5 q; Cello C3 h...'.
