TAQS.IM has released their new MicroToner MIDI Effect plugin which allows you to easily play MicroTones with any plugin or virtual instrument.
Modeled after Oriental Scale Converters, MicroToner modifies incoming MIDI Pitch Bend information to allow virtual instruments and plugins to easily play microtones.
MicroToner is a cross-platform standalone app and plugin that is supported both on PC and Mac in VST, AU, and AAX formats.
MicroToner comes with both a MIDI Effect plugin - which can be used in DAWs like Logic Pro and REAPER - and a full plugin that can be used in any other DAW.
Additionally, MicroToner comes with a vast built-in library of some of the most popular World MicroTonal scales to get started.
