VCV Rack is an open source modular synth. It’s got tons of modules. Including some popular recent creations. By default, VCV Rack is a standalone program. The MT Power Drum Kit is the ideal drum VST for the musician who knows exactly what they are wanting to achieve and prefer something that feels more realistic and intuitive. Massive sound libraries are always something I tend to look for in the best drum machine VST plugins, but sadly, I am usually let it down with lackluster drum packs. Matt Tytel’s Helm is an open-source VST synth. That means you’re free to install it anywhere on anything and tinker with the source code.

This is a list of software plugins that have full or partial support for microtonal tuning. Most are synth instruments, though some are MIDI tuners to be used with other instruments or effects to applied to audio tracks.

Helm is an unbelievably versatile, open-source VST instrument plugin. It has a huge abundance of features, including an easy-to-use step sequencer, a stutter section and even a formant function. It is perfect for beginners to understand the process of sound design, as the interface is brimming with visual envelopes, graphs and sequencers.

About software plugins

A plugin is a software synthesizer which can be accessed within a DAW. Usually the plugin is loaded on a MIDI track.

Instrument plugins interface with your DAW through one of a handful of standards. Steinberg's VST is a standard supported by many DAWs. AudioUnit (AU) is widely supported on macOS. RTAS is used by ProTools. LV2 is an open-source plugin format commonly supported on Linux. Put simply, you should check your DAW's user manual to see what kind of plugins you can run.

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.

The list

Further information about the list of microtonal software plugins is below the list.

Notes about this list

'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)'

To be added: all Homegrown Sounds synths, xen-arts

VSTHost Slavery Suite

It was just a little question in a forum... 'Is there a way to route the output of vsthost to Kristal Audio engine? And without latency?' that triggered the addition of a slave mode to VSTHost. And since I got a rather bad taste of humor, it got the above title.

When started with the parameter /slave, VSTHost goes into Slave Mode and waits for a Master to control it. The first (and currently only) master is a VST(i) plugin that can be embedded into any VST Host program (even another instance of VSTHost), called Legree. It comes as an effect and as a VSTi, since there are hosts that accept only effects, hosts that only accept VSTis, and of course hosts that accept both.

You can download Legree here (.zip file, 209K).
Current version: 1.07
Comes in 32- and 64-bit versions

Open Source Variant

Best Open Source Vst Plugins

Originally, I made VSTHost available including the complete source code. Since I had to find out that (parts of) it made their way into other people's programs, and that without even mentioning my contribution, the open source variant has been frozen. I continue to add bug fixes to the existing code base, but new features won't make their way into it any more. Starting with V1.16k, this program is released under the terms of the GNU Lesser GPL.

Anyway - the important part of the program is an implementation of a VST host in form of 2 classes:

CVSTHost

This implements the audio callback needed by an effect plugin as a neatly encapsulated VST host class. This is practically platform-independent code. The few platform-specific things are encapsulated in...

CEffect

This encapsulates a VST effect, as loaded by the VST host. This class isn't fully complete - since I don't have a Mac, I've only included the Windows code. If a kind MacIntosh programmer could fill out the few Mac-specific sections and send it to me it would be great and, of course, publicized here!
