01Overview

Predictor is built for producers and composers who are stuck or want fresh starting points. You drop a MIDI file onto it, and the plugin analyzes cadences, note relationships, velocities and other features to predict upcoming notes and voicings. You trigger each predicted note or chord with the mouse, the computer keyboard or a MIDI controller. The developer describes it as a rabbit hole for the curious, where some ideas work and some do not, and the goal is exploration.

How Predictor Turns MIDI Files Into New Ideas

Predictor includes an integrated MIDI library, and you can also load any MIDI file you like. Sampleson says the plugin learns from that material to predict chords, melodies and velocities.

The keyboard is divided into three zones: low (up to F2), mid (F2 to F4) and high (from F4 upward). Predictor estimates the next notes based on the range you play. The same logic applies to the Circles Zone. With a MIDI controller you can play triads in any range, not only the mid zone.

You set the rhythm with your taps and key presses, while Predictor chooses the notes. Your timing defines the groove of each phrase.

Playing Predictor Without a MIDI Controller

Predictor has a QWERTY playing mode that lets you play notes from your computer keyboard. It detects note-on and note-off events and predicts velocities from the learned model of your selected MIDI file, which compensates for the lack of velocity sensitivity on standard keyboards.

You can also play several notes at once, in a pianist style. The left hand can cover the lower chord range and the right hand the higher melodic zone, even without a controller.
