Stage Arranger overview

Choose where your sound comes from

Stage Arranger creates the accompaniment from your chords. The sound can come from your computer or a compatible external instrument. Choose the route that fits your equipment.

MIDI keyboard and a local bank

Your keyboard sends notes to Stage Arranger. A compatible bank on the computer produces the sounds, which you hear through the selected audio interface or headphones. For this route, keep Local audio on and the MIDI output off unless you deliberately need an external instrument.

Your own SF2 and WAV sounds

Load supported SF2 sounds or add a WAV as a playable instrument. A WAV can be an existing recording or a new sample captured from an audio input. These are ways to create individual sounds, not automatic conversion of a whole synthesizer into a bank.

An external synthesizer's sounds

The keyboard sends notes to Stage Arranger, which sends the resulting accompaniment and live parts back as MIDI. The external instrument produces the audio. It must receive the required channels and have suitable voices and drum kits. Voice selection and effects may need manual setup; this does not turn every synthesizer into a Yamaha arranger or copy its sounds.

Avoid double notes and MIDI loops

On a suitable synthesizer, Local Control Off can disconnect the keys from its internal sound generator while keeping MIDI transmission to the computer. The program then controls the receiving sound generator through the return MIDI route. Do not disable note transmission if the program needs it. The exact settings depend on the instrument. Check the receiving parts and avoid sending returned notes back to the input again.

External synthesizers

Try it first. Buy when your setup is ready.

Purchase becomes available after you connect a computer to your account. Check the sound, MIDI keyboard and response in the demo before paying. You do not need to use all your demo time first.

  1. Create your account

    Register for free and confirm your email address. Already registered? Sign in to the same account.

  2. Download and install

    Get the Windows installer in your account. A standalone sample bank is downloaded separately. You can also use an existing compatible bank or an external MIDI instrument.

  3. Connect your computer and try it

    Get a connection code in Your devices and enter it in Settings > LICENSE in the program. Select your audio, musical MIDI input and sound source, load a compatible style and try the accompaniment.

  4. Buy for the connected computer

    If the demo suits you, choose the connected computer under Licence & payment. Review the final price and terms, then pay. Check the paid device assignment in your account and select Verify again in the program.

The demo provides 60 minutes of musical use per connected computer. It requires internet access. Leaving the window idle does not use playing time. Restarting or reinstalling does not reset time already used.

Demo and full-version functions

The full licence unlocks SAVE STYLE, REC MIDI, REC WAV and microphone recording in REC SAMPLE. These functions are unavailable in the demo. Open WAV imports an existing supported audio file and is separate from microphone recording.

Current price: $99. One-time payment. Review the final amount and available payment method in your account before confirming an order.

Performance workstation

Everything you need during a live set.

Stage Arranger is centred around the arranger workflow: choose a style, play chords with the left hand, perform with layered right-hand voices and keep transport, mixer and recording within reach.

Live arranger engine

Intro, Main A-D, Fill, Break, Ending, Sync Start, Sync Stop, Auto Fill and multiple chord fingering modes.

Static Auto Mix

Auto Mix sets a static balance for the selected style and source. The applied levels are shown on the accompaniment faders, ready for manual adjustment.

MIDI performance

Record your arrangement to Standard MIDI, play it back with its stored sounds and perform a new live part on top.

WAV recording

REC WAV records the program's final local stereo output, including the microphone when its signal is routed into the mix. MIDI messages do not contain audio. To record the sound of an external synthesizer, connect its audio outputs to your interface and include that input in the recording path. Prevent feedback when monitoring the return.

MIC / Vocal

Monitor and process a microphone with Hall, Chorus, Delay and Flanger while keeping the final recording path intact.

Flexible sound sources

Choose a compatible local bank, your own SF2 sounds, an installed instrument plugin, or No Bank / External MIDI with an external synthesizer.

New in version 1.1.2

A refreshed performance interface, improved sound and instrument balance, refined chord recognition and smoother accompaniment. Version 1.1.2 also improves performance and stability.

A clearer performance screen

Updated icons, instrument browsing and clearly separated editing windows. Style and voice selection share a consistent layout, with transport information beside the chord display.

Improved sound and balance

Refined instrument playback and effect handling, with gentler balance when layering compatible right-hand voices. Keep control with the part mixer, Auto Mix and Master output tools.

More responsive accompaniment

Refined chord recognition and musical transitions. Beat indicators follow the style's time signature, including compound and irregular meters, while bar and beat information stays with the style controls.

MIDI

External synthesizers

Stage Arranger can send accompaniment and live RIGHT parts to a hardware synthesizer through MIDI. The synthesizer produces the sound; the computer sends notes and supported control messages. You can keep a local bank for simultaneous listening, or choose No Bank without loading samples.

No Bank / External MIDI

Choose No Bank / External MIDI in Settings > Sound Bank to use an external instrument's sounds without loading local samples. Select its MIDI output in Settings > MIDI and check receiving channels and supported voices. This mode does not itself produce local bank audio. Loading a local bank restores local bank playback.

Sustain Invert

If notes sustain while the pedal is released and stop when you press it, enable Sustain Invert in Settings > MIDI. This reverses the received CC64 pedal state, including for pedals without a hardware polarity switch. It applies only to live RIGHT1 and RIGHT2. It does not hold style parts or change sustain already written in a MIDI song. Release the pedal and test a few notes after switching.

Styles

Demo styles and your own library

The program includes demonstration styles for getting started. You build your own library from compatible styles you are entitled to use. You can test your own supported styles during the demo; purchasing Stage Arranger does not grant rights to third-party content.

  • A small DEMO STYLES section is kept separate from your own USER STYLES.
  • Supports compatible STY, PRS, SST and BCS style files.
  • User-created arranger Styles are widely available online and can be added to your own folder independently.
  • Stage Arranger does not bundle or endorse third-party Style collections; users are responsible for the rights to files they import.
  • Compatibility mode and the mixer help adapt Styles whose voice mapping or balance differs from your current sound library.

Start with the demonstration styles, then browse your own folders of compatible styles. The user collection shown here is an example and is not included with the program.

User Style compatibility

Different Styles can need different tuning.

Third-party and converted Styles are not all programmed the same way. A supported file may use source-specific voices, controller data or arranger rules, so we do not promise that every external Style will sound identical to the keyboard or software it came from. Stage Arranger is an independent product and is not affiliated with or endorsed by third-party keyboard manufacturers.

Yamaha is a trademark of Yamaha Corporation. Stage Arranger is independent and is not affiliated with or endorsed by Yamaha. Compatibility describes supported file handling, not ownership of third-party styles, samples or sounds. Use content only where its licence permits your intended use.

Voices, banks & Auto Voice

Build the sound setup that fits your repertoire.

Layer RIGHT1 and RIGHT2, choose their sounds and set separate voice octaves. Four Auto Voice slots store style-specific setups; the link option recalls them with Main A-D.

  • Choose a compatible local bank, your own SF2 sounds, an installed instrument plugin, or No Bank / External MIDI with an external synthesizer.
  • Separate VOICE OCTAVE for each RIGHT part, plus UPPER OCTAVE and transpose.
  • Four editable Auto Voice slots, with optional Main A-D linking.
  • Edit all four Auto Voice setups in one style session, then save them together.
Voices, banks & Auto Voice
Mixer & Auto Mix

A starting mix you can see, and then make your own.

Auto Mix sets a static balance for the selected style and source. The applied levels are shown on the accompaniment faders, ready for manual adjustment.

  • RHY1, RHY2, BASS, CHD1, CHD2, PAD, PHR1 and PHR2 remain visible at all times.
  • Mute, Solo, channel volume, pan, filtering, EQ and effect sends.
  • No constantly moving faders or delayed corrections during section changes.
Mixer & Auto Mix
A complete output stage

Shape the mix. See what you hear.

Five-band EQ, stereo-linked compression, dedicated makeup gain and a shared Master fader put the final sound in your hands. Input, output and gain-reduction meters show what the processor is doing.

Save the full setup in CONFIG. Keep your Auto Voice edits in SAVE STYLE. Two clear workflows, one performance.

Play it your way

An accompaniment that follows your hands.

Responsive chords, protected release changes and musical transitions keep the focus on the performance.

Expressive left-hand control

Add chord tones while playing. Release protection helps avoid unintended intermediate harmonies as you lift your fingers.

Musical transitions

Breaks and fills retain their programmed timing, with controlled note tails instead of extra attacks inserted at the change.

Four setups, one save

Personalise each Auto Voice, switch between them within the style session and write all edited slots in one save.

MIDI Player

Record the arrangement. Play the live part later.

The built-in MIDI Player shows the song as a compact piano-roll overview, keeps the sounds recorded with the performance, and gives you play/pause, stop, seek and timeline control directly inside the main display.

  • Play back Stage Arranger MIDI with stored program information.
  • The arranger is locked during playback so a second accompaniment cannot start accidentally.
  • The full keyboard remains available for live RIGHT performance.
  • Record the MIDI playback, live solo and microphone together to WAV.
Audio, vocal and sound modules

Connect the workstation to your real setup.

Use an audio interface, a hardware MIDI keyboard, a microphone and the sound source that fits your performance.

Sing, play, capture

Build ideas and demo recordings in one performance flow.

Place a microphone on a stand, play the keyboard, sing your part and capture the result without leaving the Stage Arranger workflow. It is equally useful for home demos, rehearsal ideas and performance-ready backing tracks.

  • Use a MIDI arrangement as the backing track while you perform a new live part.
  • Sing through the microphone path with monitor effects and record the final result to WAV.
  • Keep the take as a personal demo, send it to collaborators or continue with AI-assisted or DAW-based production later.
  • Perfect for solo performers, songwriters and compact home-studio setups.
User sounds · SF2

Favourite sounds and styles within reach

Keep bank sounds and SF2 presets together in Favourites, mark favourite styles and quickly find what you need for a performance. Browse categories and choose instruments in a clear visual browser.

Your own SF2 and WAV sounds

Load an existing WAV

Open REC SAMPLE and choose Open WAV to import an existing supported WAV. Set the root note to match its pitch, adjust the start, end and fades as needed, then use Add voice. Save edited audio with Save WAV as before adding it. Keep the WAV available at its saved location when recalling the configuration.

Record a new WAV sample

Connect a microphone or the external instrument's audio output to an appropriate audio-interface input. Select and check that input in the MIC settings, then open REC SAMPLE and press Record. Stop earlier or let capture stop at 20 seconds. Set the root note, save the WAV and use Add voice. Audio-input recording requires the full licence. MIDI alone does not carry the sound to record. REC WAV records the final performance mix instead of creating a short instrument sample.
