Entonal Studio is a microtonal plugin and standalone application designed to retune any VST or AU virtual instrument with ease. It features a unique radial graph interface and flexible keyboard mapping options, allowing users to intuitively adjust individual notes within their digital audio workstation or beyond. Acting as both a MIDI plugin and a host for VST and AU instruments, Entonal Studio eliminates the need for complex MIDI routing to transform favorite synths or instruments into fully microtonal setups.

Users can retune scale notes by color and angular position, drag notes freely in cents, or snap them to equal divisions of the octave or simple ratios within a prime limit. The plugin also provides harmonic visualization tools that display relationships between intervals and chords, helping to ensure harmonic alignment. A comprehensive browser offers access to a wide range of tuning systems, from common just intonation and 19-tone equal temperament to more exotic options like 43-tone Harry Partch scales and 7-limit Hexany, with support for importing and exporting Scala tuning files.

Entonal Studio supports detailed customization of scales with up to 192 notes, allowing users to define repeating intervals, root notes, and note mappings to MIDI controllers or DAW piano rolls. Multiple plugin instances can be linked to synchronize tuning changes across tracks, streamlining complex microtonal workflows. Additionally, the built-in simple synthesizer enables immediate auditioning of tunings without external connections. Compatible with AU, VST2, and VST3 formats, Entonal Studio offers a flexible and powerful environment for exploring and creating microtonal music.
