Create beautiful notes and harmonies by simply clicking your mouse.
Standalone App + VST3/AU plug-in. Win and Mac.Predictor is a plug-in and app that generates notes, triads and voicings with simple clicks. It works by learning from existing MIDI files to predict new notes and chords.
Ideal for sparking fresh ideas or breaking through creative blocks.
It comes with an integrated MIDI library, but you can also load any MIDI file you like and Predictor will learn from it.
See it in action
Predictor learns from any MIDI file to generate upcoming notes and voicings.
Predictor is a generative MIDI composition tool that can learn from the MIDI file you drop onto it. It analyzes cadences, note relationships, velocities, piece position, modulations, and other features to predict new notes and voicings that you can then trigger with the mouse, the computer keyboard, or any MIDI controller.
You control the rhythm, Predictor handles the notes. Each tap or trigger you perform launches the next predicted note or chord, so the flow of the phrase depends entirely on your timing. This makes the experience feel more expressive and connected — you're not just listening to generated ideas, you're actively shaping how they unfold.
A rabbit hole for the curious.
Despite its simple idea, Predictor can help you take unimagined paths. Some will work, some won’t — and that’s part of the process. The point isn’t perfection, it’s exploration. With each click, you’re invited to discover something new — a melody you wouldn’t have written, a chord that changes the mood, a sequence that opens up a track. Sometimes it’ll feel random, other times it’ll feel like magic. But either way, it keeps you moving, thinking, experimenting. Predictor doesn’t promise certainty — it offers momentum. And sometimes, that’s exactly what you need.
Generation ranges and zones
Predictor estimates the next notes based on the keyboard range you play. It divides the keyboard into three zones: low (up to F2), mid (F2–F4), and high (from F4 onwards). This logic also applies to the Circles Zone. You can trigger single notes or chords in each range using your QWERTY keyboard or mouse clicks. With a MIDI controller, you get added flexibility to play triads in any range, not just the mid zone.

MIDI CONTROLLER PLAYING
You are in charge of rhythm.
Predictor co-creates with you. It takes your tap on computer keys, clicks, or notes from a MIDI controller to generate voicings and melodies. You'll be in charge of the rhythm, while Predictor will take care of the rest, proposing phrases to kickstart your next song idea.
Predictor takes care of what notes come next, but it’s your timing that gives them life. Every tap or key press defines the groove, and that’s what shapes the feel of the phrase. You lead with rhythm, Predictor follows with sound.

QWERTY PLAYING
No controller? No problem. Predictor features a QWERTY playing mode that lets you play notes directly from your computer keyboard. It detects note-on and note-off events while intelligently predicting velocities based on a learned model from your selected MIDI file. This ensures a more natural playing experience, compensating for the inherent lack of velocity sensitivity on standard computer keyboards.
Predictor also enables you to play multiple notes simultaneously, mimicking a pianist's style. You can use both hands to create rich, dynamic performances: the left hand naturally covers the lower "chord" range of a piano, while the right hand takes control of the higher melodic zone. This intuitive layout not only emulates the traditional pianist approach but also allows for more expressive and realistic performances, even without a MIDI controller.
