List of Microtonal Software Plugins has been updated

The Xenharmonic Wiki is an online knowledge base relating to microtonal music and tuning theory. For a few years a bunch of us from the community have used the Xen Wiki to maintain a list of software plugins that you can use to make microtonal music in the DAW.

This week the list has been updated because of wonderful developments happening in the music technology world that will allow composers to more easily make microtonal music with a wide variety of synths and virtual instruments. That development is the widespread adoption of MIDI Polyphonic Expression (MPE). Widespread MPE support means that new tuning tools can be developed which systematically manage the tunings of various instruments at the same time. And indeed, such tools are already coming out this year, for example Oddsound MTS-ESP Suite and Infinitone DMT. A new section of the list has been added to catalogue these tools. An additional section about MPE synths in general was also added.

Micro is Massive! Sevish live stream on Saturdays

Next Saturday (March 13th, 5pm UTC) I’ll stream from my home studio via Twitch. It’s a chance for me to demonstrate electronic music production and working with microtonal scales. If there’s something in particular you’d like to see then send your requests in Twitch chat – it’s an unscripted event where we hang out and nerd out over music.

From time to time I’ll also live stream impromptu sessions of me just working on tracks. These will be unscheduled as I make music whenever I feel like it. Those sessions will be less interactive but potentially of interest to folks who are following my music and want to see how I work.

Consider following my Twitch channel if you want to get the alert when I go live: twitch.tv/sevishmusic

Until then, check the below vod of last Saturday’s stream. It starts out with me refining a work in progress and then viewers suggest topics for the rest of the session:

I learned a few things from chat last Saturday, for example x.iso encouraged me to try MPE polyphonic pitch bend in Bitwig on VST instruments that already have microtunings active. Turns out that it works! If you’re working in any equal tuning, you can set the pitch bend amount so that everything lines up perfectly. My mind was blown. I’ll definitely use that trick in the future.

Leimma & Apotome: two new web tools for microtonal music

Two new tools have just appeared that will interest folks working with microtonal scales and tunings: Leimma and Apotome. These tools were launched as part of CTM Festival 2021 and were created by Khyam Allami and Counterpoint.

Leimma

Leimma is a browser-based tool for exploring, creating, hearing, and playing microtonal tuning systems.

Apotome

Apotome is a browser-based generative music environment based on octave-repeating microtonal tuning systems and their subsets (scales/modes).

Making microtonal scales with Scale Workshop 1.0

A new web app called Scale Workshop allows you to design and play your own microtonal scales. You can also tune various other synthesizers with it. It has just reached version 1.0 and is now recommended for use by the wider musician community.

Scale Workshop has these aims in mind:

  • Scale creation. Use the tools to generate and modify tunings automatically, or manually input your own.
  • Import Scala and AnaMark tunings. Yes it works with that amazing 4000+ scale library that’s floating around the internet.
  • Export the most popular tuning formats easily. Converting .scl files and .tun files is fast. It also exports tuning files for Kontakt, Max/MSP and PureData.
  • No installation required. Scale Workshop runs in your web browser on Windows, macOS, iOS, Android and Linux.
  • Free and open-source. The software costs nothing and it is MIT licensed. Volunteers have already contributed new features and bug fixes on our GitHub repository. Feature requests and bug reports are welcome from anybody.

What else does Scale Workshop do?

Scale Workshop puts a polyphonic synth right inside your browser. You can audition and perform your scales by playing with a connected MIDI controller, QWERTY keyboard, or by using the touch-screen overlay.

Convert scl files and convert tun files to various tuning formats. Export formats include Scala .scl/.kbm, AnaMark TUN, Native Instruments Kontakt tuning script, Max/MSP coll text format and Pure Data text format.

Share your scales with other people by copy-and-pasting the URL in your address bar while working on your scale. The recipient will instantly see your scale information and can play it using their keyboard. This is invaluable for communicating your tuning ideas with others, or allowing your musical collaborators to export your tuning in whatever format they prefer. Try it out.

Display frequencies, cents and decimal values for your tuning across all 128 MIDI notes.

A personal note

This has been a labour of love for almost 2 years – I hope that many people will find it useful! If you want to share any work you’ve created with Scale Workshop then I’d love to hear about it.

Now that Scale Workshop is in a stable state, I am going to focus my attention back on composing new music and hosting the Now&Xen microtonal podcast.

Informative videos about microtonal music on YouTube

I’m always keen to see how other musicians are creating microtonal music and the ideas behind their craft. For a few years now I have been building a YouTube playlist of microtonal music tutorials and explanations. As the playlist now has over 140 videos, it’s a good time to share these hours of content with others.

One thing that makes microtonality fascinating is that the newcomers are exploring new tonal structures that even the old masters haven’t heard of. But new or old, when a musician shares their insight in a video, I include it in the above playlist.

The playlist features videos from: Tolgahan Çoğulu, Adam Neely, Dolores Catherino, minutephysics, This Exists, Elaine Walker, Stephen James Taylor and others.

amsynth 1.8.0 adds support for microtonal tunings

Of all the software synths in the world, very few of them support microtonal scales. If you are a musician using Linux and open source software then your options are even fewer. It’s for that reason that I want to celebrate the news that amsynth 1.8.0 adds support for microtonal tunings!

amsynth is a virtual analog synthesizer that runs as a standalone or VST, LV2 or DSSI plugin. Its sonic characteristic is similar to other popular digital VA instruments – fantastic for leads, basses and stabby chords. It’s light on the DSP and the controls are very easy to understand, so amsynth will rightfully earn a place in my toolkit once I move my music production machine over to Linux.

Installing

The easiest way to get amsynth if you’re on a Debian-based distro is to add the KXStudio repositories and then install via apt. Assuming you already have the KXStudio repos on your system, simply run the following command:

sudo apt install amsynth

If you’re unable to use the above, download the source for amsynth 1.8.0 and build it.

Tuning amsynth

Once you have amsynth up and running, microtunings can be loaded by right clicking the interface and selecting a .scl file. In addition, you can load up a .kbm file for custom key mappings.

If you need some Scala tuning files (.scl) to play with, generate some with my Scale Workshop browser tool, or install Scala itself. Scala is extremely powerful, though you need to install it to your PC along with all its dependencies.

Full-keyboard microtuning

Developers, TAKE NOTE of what amsynth developer Nick Dowell has achieved here – .scl and .kbm formats are BOTH supported. .scl files specify the intervals in the scale, and .kbm specify the base tuning of the scale, whether it is A = 440 Hz or something else entirely.

Without supporting both of these formats, a synth could barely be said to support microtonal scales at all. I’m so pleased that amsynth gets this right.

The future

Judging by this page on amsynth’s GitHub, it looks like amsynth may become cross-platform in the future. Should this ever happen, then Windows and Mac users would also have access to this nifty, free and microtonal instrument too. I look forward to this and will follow amsynth’s progress into the future.

‘Retune for Live’ microtuning with Max 4 Live, by Ursine

Retune for Live is a Max 4 Live MIDI device which accepts MIDI notes as input, then outputs polyphonic microtonal MIDI which you can route to your MIDI instruments. It works on instruments that don’t support microtonal scale input, as long as they respond to pitch bend. You specify the microtuning via csv file or scl tuning file.

It all works simply enough. You have one MIDI track where you can play and record polyphonic MIDI. The Retune for Live transmitter device sits on this track and beams the note & pitch-bend data intelligently to a number of receiver devices, each of which working for one monophonic part. So if you want 8-note polyphony then you must have 8 instances of the instrument/VST each driven by their own receiver device.

When I write microtonal music I usually rely on VSTis which have support for full-keyboard microtuning built in. There should be no compromises in your art – and my art is microtonal so if a synth has no microtuning or dodgy microtuning then I don’t use it at all.

Except that for a long time I have wanted to hear Clotho from the Columns soundtrack rendered in quarter-comma meantone tuning. To faithfully recreate the sound of the original game, I set out to use a YM2616 simulation. I found two YM2616-esque VSTs, GENNY and FMDrive, but GENNY doesn’t even have working pitch bend, so that’s straight out the window.

Sega Columns

So I got myself a copy of FMDrive and downloaded a MIDI file of Clotho. MIDI retuning via Scala seemed dodgy and I could hear the results were wrong. After one night of trying different things I gave up. TobyBear’s microtuner is ancient and I couldn’t even get the ruddy thing to work at all. This is all a roundabout way of saying…

I tried Retune for Live and it just worked! So if you have Max 4 Live and want to get microtonal sounds from a synth that can’t be microtuned, give it a try. You can download Retune for Live for free or pay-what-you-like donation from the author Ursine.

As much as this solution was successful in my case, it uses more CPU power since you have to run multiple instances of the same instrument. For that reason I will avoid this solution for larger projects. But if you really need a certain sound (and you already paid big buck$ for Ableton Live and Max 4 Live), then Retune for Live might be the way to go.

Several months after my explorations with Retune for Live, I did convince the developer of FMDrive to implement some microtonal functions, but that’s a story for another day. As for my quarter-comma meantone rendition of Clotho, that was sadly lost in the great didn’t-back-it-up-and-hard-drive-died catastrophe of Spring 2016. It was badass though, I’ll remake it one day.
