Stage Arranger is arranger software for Windows that turns your PC and any MIDI keyboard into a virtual arranger keyboard. Your left hand plays the chords, the auto accompaniment follows with drums, bass, guitars and pads, and your right hand is free to play and sing. No tracks to build. No piano roll. Just music.
Already 23% off. Your code takes another $20 off.

Built to be played,

Most music software asks you to become an engineer first. Tracks, clips, quantize, export. Stage Arranger asks one thing: play.
Pick a style, touch a chord, and a band that listens to your hands starts with you. Switch to Main B for the chorus, hit a Fill into the bridge, land the Ending. This is live accompaniment software that works the way arranger keyboards have worked on stage for decades, now on the Windows PC you already own.
An arranger panel,
under your fingertips.
Stage Arranger recognises the chord you play and moves the whole band with you. Every section of a song is one key away. Mapped to F1 through F11, Space and Enter on your computer keyboard.
Play a chord with your left hand and drums, bass, chords, pads and phrases follow in time and in key. Several fingering modes, from single finger to full chords.
Intro, Main A to D, Fill, Break and Ending. Auto Fill on section changes, Sync Start on your first chord, Sync Stop when you lift your hand.
Load compatible SFF and SFF2 style files you already own into a User Styles library, next to the included demo styles.
Use a compatible sound bank, your own SF2 files, installed instrument plugins, or an external synthesizer over MIDI.
Open any Standard MIDI file, mix its channels and play or sing along with live right-hand voices.
Record MIDI, or a finished stereo WAV of the whole mix, including your microphone with Hall, Chorus, Delay or Flanger.
ASIO driver support with buffer size control, so the band answers your hands like a hardware instrument.
Eight-part mixer, Auto Mix, per-part EQ, filters and effects, a master compressor and a five-band EQ. On Windows 10 or later, 64-bit.
Take the full tour.

Style, tempo, chord, section and all eight accompaniment parts on one screen. The keyboard shows your split point: amber for chords, blue for melody.

Browse by category, search, mark favourites. Load a bank, point to your own SF2 folder, use installed instrument plugins, or drive an external synth over MIDI.

Five-band EQ, a stereo-linked compressor with makeup gain, stereo width and a limiter ceiling. The final polish before your speakers or the recording.

Open a MIDI file, mix its channels and play or sing along with the right-hand voices live. Ideal for backing tracks you already have.

Capture a sound from your microphone, trim it, add fades, set the root note and turn it into a playable voice.

ASIO driver support, buffer size control and channel routing. Pick your interface once and play with the immediacy of hardware.
