What Predictor does
The plugin works by learning from MIDI files: a dropped MIDI file is analyzed, and the next notes and chords follow the patterns found in that material. An integrated MIDI library is included, so the learning can start without any files of the user’s own. Real-time playback generates the notes as triggers are played.
The keyboard is divided into three zones, low up to F2, mid from F2 to F4 and high, and the prediction logic applies to each range. Single notes and chords can be triggered in each range with the QWERTY keyboard, the mouse or a MIDI controller, and a controller allows triads in any range rather than only the mid zone. Crack, cracked and keygen searches for Predictor usually name the Windows build, and the macOS release circulates as a .dmg crack, while the repack is packed as .rar and .iso, and a working serial key is the string most often typed next to the name.
Torrent and magnet link copies of Predictor appear next to terms such as VST crack, AU crack, x64 crack and x86 crack, and the Windows build is listed as win/mac crack in the same searches.
Key features
- Learning from MIDI files. Any MIDI file dropped onto the plugin is analyzed, and the next notes and chords follow the patterns found in that material.
- Zoned generation. Three keyboard zones, low, mid and high, each apply the prediction logic, so the same tap can produce different note ranges.
- Multiple input methods. Notes can be triggered with the mouse, the QWERTY keyboard or a MIDI controller, and simultaneous multi-note playing is supported.
- Included sounds and library. Three sounds are included for sketching, together with a library of MIDI files that can be used as learning material.
- Scalable interface. The interface is scalable and supports 4K displays.
Use cases
- Breaking creative blocks. The developer positions the plugin for composers and producers who want fresh material, with each tap launching the next predicted note or chord.
- Sketching phrases. Phrases can be built by playing chords and melodies with the keyboard or a controller, then refined in a DAW.
Compatibility
Predictor comes as VST3, VST2, AU and Standalone for Windows 7 and later and macOS 10.7 and later, in 64-bit builds, with native Apple Silicon support listed and 4 GB of RAM required.
Who it is for
Composers, producers and musicians who want to generate notes, chords and voicings from examples of existing MIDI material, and who want the process to suggest unexpected paths.
