Entonal Studio: Microtonal Tuning Plugin by Node Audio

The radial graph shows scale notes by colour and angular position, so you can drag a note freehand in cents or snap it to simple ratios within a chosen prime limit. You can also view the relative intervals between two or more held notes to check how they align.

The scale editor works from a list. Add or remove notes and type each value as cents, ratios, EDO degrees or a mathematical expression. For scales that do not repeat at the octave, you can set the ratio of the repeating interval instead of assuming 2/1.

Scales can contain up to 192 notes, and you can generate equal temperaments directly. Scala and Tuning XML files can be imported and exported, which makes it easier to move scales between tools.

Entonal Studio can host AU, VST2 and VST3 instruments, so the tuning and the sound live in one plugin chain. Its built-in simple synthesizer is available if you want to audition a tuning without loading another instrument.

Group plugin instances to link tunings between tracks in a project. This keeps a microtonal system consistent when several parts use the same scale.

In Bitwig Studio, FL Studio and Studio One, the DAW piano roll can display note values as note names, which helps when reading microtonal parts. A tuning information table covers octaves from -2 to 8, and the view can switch between a traditional keyboard, a white-notes keyboard or an MPE keyboard.
