Theory-driven roles
Intelligent Musical Roles
Assign a musical Role — Melody, Arpeggio, Chords, Bass, Pedal, or Motif — and the engine generates a complete, musically intelligent phrase conforming to your overarching harmonic roadmap.
Explore the full depth of OrchestraX — from one-click phrase generation to granular MIDI sequencing, from intelligent voice leading to expressive dynamics shaping. Every parameter speaks the language of music theory.

A powerful generative musical engine that produces complete, orchestrated, and context-aware elements natively matching your template.

Theory-driven roles
Assign a musical Role — Melody, Arpeggio, Chords, Bass, Pedal, or Motif — and the engine generates a complete, musically intelligent phrase conforming to your overarching harmonic roadmap.
The melodist pipeline
The melodist implements a classic composing structure: creating a rhythm skeleton first, defining melodic anchor points, and weaving passing notes, broderies, and arpeggiated figures seamlessly.
Micro-controls
Shape every clip with parameters that speak music: density, complexity, polyphony, spread, syncopation, phrase length, and octave placement. No technical math, just absolute musical control.
Spark new creative directions with surgical randomization tools designed to inject organic variations without destroying your thematic foundation.
Randomize everything — orchestration, clips, and chords for the entire composition or current theme.
Randomize selectively — orchestration only, chords only, melody clips only, or a single isolated clip.
Shift and randomize the internal beat accents of any selected clip to humanize dynamic stresses.
Perform per-bar chord randomization within the bounds of a selected scale mode for instant harmonic exploration.
Build complex modal architecture with zero guesswork. The harmony engine understands the constraints of traditional voice leading.

Chord track
A dedicated chord track with per-bar control. Add, split, merge at bar, theme, or overarching composition level.
Extensions
Instantly flavor your progressions with complex jazz or classical chord extensions and tensions per bar, per theme, or composition-wide.
Solvers
Smart recursive and CP-SAT solvers automatically calculate the smoothest possible transition when chords change. Melodies and accompaniment figures track the harmony intelligently, avoiding parallel octaves and awkward leaps.
Ditch flat mechanical playback. Generate organic velocity curves, multi-articulation key-switches, and smooth MIDI CC modulation that matches natural player behaviors.

Timeline shaping
Draw continuous Intensity and Space curves over your entire timeline to dictate how thick or intimate the orchestration becomes as the piece progresses.
MIDI modulation
Generate customizable CC curves per clip — Dynamics (CC1), Expression (CC11), or Vibrato (CC21) — with advanced per-bar regularity and natural humanized noise options.
Velocity modelling
Intelligent beat accent models calculate realistic ratios for downbeats versus off-beats, incorporating performance tolerances that replicate a live symphonic layout.
Attack and deviations
Synthesize organic brass swells and sudden accents with a sophisticated envelope engine driving amplitude, center, and humanized deviation curves.
The flexibility of a standalone app with the control of a traditional piano roll. Bridge the gap between algorithmic generation and tactile composition.

Piano roll
A pristine, integrated piano-roll complete with a vertical keyboard layout, note pitch velocity adjustments, responsive scaling, and smooth timeline zoom.
Context
View your arrangement globally. The selected clip is highlighted in crisp high-contrast while adjacent tracks are subtly ghosted and dimmed in the background.
Freedom
Absolute freedom: choose to regenerate entire phrases algorithmically, or zoom in to drag, stretch, delete, and place individual notes manually directly inside the grid.
OrchestraX adapts completely to your existing custom templates. No proprietary formats, just elegant, robust routing parameters.

Studio compatibility
Load pre-configured articulation maps or build custom matrices matching major developer libraries — Spitfire, Orchestral Tools, Cinematic Studio, EastWest, and more.
Overlap detection
Designate playable register ranges and place keyswitches. The system automatically highlights overlaps and adjusts constraints to avoid silent note triggering.
Middle C convention
No more transposition confusion. Seamlessly toggle between Yamaha and Roland middle-C conventions per instrument to keep keyswitches perfectly aligned.
A revolutionary hybrid connection framework that brings the power of standalone composition directly inside your existing host DAW project.

Standalone
The primary host application is the Brain. It is here that you sketch, compose, adjust harmonies, and execute algorithmic orchestrations within a distraction-free, native 64-bit sandbox.
Plugins
Each track inside your DAW hosts an OrchestraX Chair plugin. Think of it like seating a live musician in the orchestra. The Chair automatically registers its track position, listens to the Brain, and feeds live MIDI directly into your sample libraries.
Sync
Erase routing headaches. Simply load a Chair plugin onto a track, and it pairs with the Brain over a zero-latency internal network bridge. No virtual loopback ports, no custom network setups, no configuration files.
OrchestraX respects both your raw initial concepts and your ultimate final deliveries. Native export pipelines get your MIDI into production instantly.
Drag full multitrack compositions or isolated articulation clips directly out of the Brain timeline and drop them onto your DAW timeline — complete with all generated CC curves.
Compose in complete isolation on a plane or train. The built-in synthesizers provide instant, high-quality audio feedback without launching a single heavy sample library.
Experience absolute sketch security with a recursive undo/redo matrix spanning chords, orchestration changes, clip edits, and parameter re-rolls across all timelines.
Quickly refine select notes or global tracks. The responsive sidebar inspector displays dynamic, context-aware parameter micro-controls for whatever element you select.
A studio space crafted strictly to shield you from technical friction, ensuring absolute mental focus on harmony and emotion.
