List of microtonal software plugins
Jump to navigation
Jump to search
This is a list of software plugins that can be used in a DAW for creating microtonal music.
What are plugins?
Computer musicians typically use a DAW to create music. Plugins provide extra functionality within your DAW. For example, if your DAW doesn't allow microtuning then you can get that functionality via plugins.
Plugins featured on this page are typically either:
- Software instruments that have built-in tuning functionality (e.g. synthesizers, samplers)
- Tuning tools that alter the tuning of other instruments, plugins and/or audio clips but otherwise do not generate sounds themselves
Before purchasing a plugin, you should check your DAW's user manual to see which types of plugins it supports. In many cases you can try a free demo to make sure it works as expected. Plugin types include:
- VST3 by Steinberg, widely supported. VST2 is also by Steinberg, who discontinued it in 2018. But most Windows versions of non-Steinberg DAWs still support VST2 as of 2023.
- AU by Apple, widely supported on macOS only.
- AAX by Avid, used in ProTools, and RTAS, obsolete format which was used in ProTools until version 10.
- LV2, CLAP (site) and DSSI (obsolete, replaced by LV2), open-source cross-platform plugin formats.
- NKS by Native Instruments, used with their hardware.

- Notes
- "Full-keyboard microtuning" means that the plugin is capable of any arbitrary pitch, note or frequency on any given MIDI note. This is possible via .tun format, MIDI Tuning Standard, and .scl/.kbm pairs (but not .scl support on its own).
- All synths in the list are assumed to be 64-bit by default or offer an option of 32- or 64-bit. Synths that are 32-bit only are marked with "(32-bit)"
- For distinction of free software and freeware, see Wikipedia: Free software and Wikipedia: Freeware.
- In some synths, portamento/glide doesn't work properly when microtuned. Examples are Xfer Serum and LinPlug synths. There may be others, so it is recommended to test this function before making a purchase, if it is important for you.
- There are plugins retunable by MTS-ESP (see below) which aren’t in this table. See them on the official MTS-ESP page.
- The list there seems incomplete as of January 26, 2023: Full Bucket Audio states that their plugins MPS, Tricent mk III, Stigma, FBVC, Mono/Fury, The blooo,The scrooo, The qyooo now have MTS-ESP support, but these aren’t in the list yet.

MIDI remapper plugins
These plugins are neither instruments nor tuners but are useful when working with those, remapping notes input to the plugin, presumed to be in one tuning or a mode of a tuning, to the notes the plugin outputs, presumed to be in another tuning. For example, making you use just a MOS subscale of an output equal-division tuning.

MPE-compatible software instrument plugins
A recent development in music technology is MIDI polyphonic expression (MPE). Instruments that support MPE are able to apply pitch-bend on a per-note basis. In theory, this allows a musician to create polyphonic microtonal music using any MPE-compatible synth. In practice, it is a laborious process to create microtonal music by specifying a pitch-bend on every single MIDI note. However some plugins shown in the above "Tuner plugins" table can intercept MIDI note data from the sequencer and systematically apply the correct per-note pitch-bend before that data is received by the instrument. Because of this, creating microtonal music with MPE-compatible instruments is now a viable approach.
