Download Plugin Boutique Scaler 1.2 Free Download Latest Version for Windows. For VST hosts, Scaler loads as an instrument plugin onto a MIDI track, the output of which is sent to a second track (hosting the target instrument) using the DAW’s routing system. Obviously, though, the idea is to trigger other instruments via Scaler, and how this is set up depends on the host DAW. Scaler is a unique and inspirational MIDI effect that makes finding chords and progressions intuitive and fun! With note detection, scale selection and chord suggestions, Scaler is a comprehensive but easy-to-use toolbox that will help anyone make better music.
