Microtuning Support for Decent Sampler

Version 1.8.0 of Decent Sampler offers microtuning support via the Tuning menu. You need to supply it with an scl and kbm file, which can be easily generated with Scale Workshop, Scala, or other tuning creation tool.

Surge XT is a software synth plugin. Version 1.2 is now released. This version improves upon its tuning functionality, accessibility and other things. An excerpt from the changelog reads:

Major Feature: Tuning Upgrades

• Surge can act as an OddSound MTS provider (‘master’) allowing the Surge tuning editor to provide tuning to an entire session.
• Remediate yet more edge cases in our internal tuning, including keyboard mapping larger than a scale.

The short explanation is, if you are using synths that support tuning via MTS-ESP, Surge XT can now act as the MTS-ESP master, which means that you specify your tuning within Surge XT and then the other synths will follow the same tuning. This is intended to be more convenient than loading the same tuning data into multiple instances of various synths.

Surge XT is free and available on Linux, Windows and macOS.

With the recent release of Scale Workshop 2, lead developer Lumi Pakkanen has started producing video tutorials to demonstrate what this tuning application can do. Learning some Scale Workshop basics will aid you in your study of musical tunings. The first two videos are below. For the rest, you’ll have to follow Lumi’s youtube channel.

1. Basic synth interface

This tutorial demonstrates the on screen keyboards where you can play microtonal scales in your browser.

2. Data entry

This tutorial will answer a lot of questions about how you can enter your own scales from numerical values.

Learn Scale Workshop

Since Bitwig Studio is a pretty good DAW for making microtonal music, you might find yourself working with a musical scale that contains more or less than 12 notes. Particularly if you’re working with a large scale, you will want the piano roll to visually reflect what you’re hearing. You might have thought this was not currently possible in Bitwig Studio but I have found the quick workaround for you. All you need is to watch the tutorial video below and then spend a few minutes setting up your custom piano roll.

The tutorial music is Yeah Groove from my very recent album Morphable, in 26 tone equal temperament.

I just added some more of my fractal artwork to the gallery page. Go check them out!

My new album Morphable will be available on 5th August 2022. Nine new electronic microtonal beats from the harmony hacker.

If you want to hear one of the tracks today then you can! Yeah Groove can be played on youtube:

Scale Workshop has been updated this weekend. Let’s take a look at what this useful microtonal web tool is capable of.

Launch Scale Workshop in a new tab

Key functionality

• Create your own microtonal scales by direct data input, or use one of the many generator methods to aid your discovery.
• Export tuning files in a large variety of useful formats.
• Hear the scale by using your qwerty keyboard as an isomorphic keyboard, or use MIDI input (requires a browser with web MIDI support).
• Import Scala scl file and convert to various formats.
• Collaborate and share your scale easily by copy and pasting the URL which automatically has your scale encoded.

Recently added features

MIDI I/O

With a web MIDI compatible browser, you can use Scale Workshop to enable microtonality on your hardware synths and sound modules. This is achieved by 16 channel note output with pitch bend on each channel.

Rotate modifier

Rotate your scale so that a different interval becomes the new 1/1.

Improvements to the virtual keyboard

When using the mouse cursor, you can now play the virtual keyboard stylophone style, i.e. click and drag across the keyboard to hit a sequence of notes.

Export REAPER Note Name Map

REAPER supports custom piano roll layouts. You can now export a txt file from Scale Workshop to import directly into REAPER.

Export tuning to Korg Monologue/Minilogue XD

Export your tuning to Korg Librarian format. This can be imported into the Korg Librarian software so you can write it to your synth.

Better precision

Scale Workshop now has better handling of large numbers and ratios.

Better synth

Issues with the synth audio dropout are resolved. Various new waveforms are added. The default waveform is changed to semisine which is more ideal for auditioning tunings than the previous triangle.

User guide updated for 1.5

As this version is a major milestone for the app, we have made sure to update the documentation to cover all the new features.

The future of Scale Workshop

Early development work has started for Scale Workshop 2. This involves a complete rewrite from scratch and a new UI. The project will remain on the permissive MIT License so that synth developers can re-use parts of Scale Workshop’s code to add microtonal functionality to their own projects. Scale Workshop 2 is intended to be released when it reaches feature parity with Scale Workshop 1.5. Scale URLs will remain backwards-compatible. Scale Workshop 1.x will receive no new features except for bug fixes.

• Developer/support chat is on Discord: Sevish’s server #scale-workshop
• New GitHub repo for Scale Workshop 2 specifically
• Use the app and let your buddies know

Gleam is perhaps the iconic Sevish track (or so I am told), but have you ever wondered how it was made? Lumi’s recent video analyses Gleam from a music theory perspective, explaining how I used 22-tone equal temperament (22ed2) to make a catchy piece of music.

Here are some of my thoughts on various microtonal scales. These thoughts are my own subjective impressions and there’s no need to take them seriously. Enjoy!

Equal-step tunings

• 1edo – wide-open featureless space
• 2edo – dual opposition
• 3edo – dreamy flashback, bells
• 4edo – cartoony horror, staircase
• 5edo – open, bright colour, ease
• 6edo – cartoony wonder, tension
• 7edo – flat, comfort, bright colour
• 8edo – moist shit
• 9edo – bells, chimes
• 10edo – vivid, open
• 11edo – pure, warped, intuitive
• 12edo – nostalgia, comfort, jazzy, transparent
• 13edo – warped liminal space
• 14edo – multicoloured
• 15edo – wonky
• 16edo – expressive
• 17edo – angular, intuitive, colourful
• 18edo – bright colour, I still haven’t explored this one
• 19edo – flat, wonky, uncanny, pale
• 22edo – chill, trippy, hyper-jazz
• 23edo – bright colour, unstable
• 24edo – something you think should be familiar is now wretched, hyper-jazz
• 29edo – expanded wonky wonder
• 31edo – rest, clarity, transparency, and once you get this far out, each edo has the capacity for extreme variety
• 314edo – way too many notes. this is the point where you’ve gone too far

Bonus, here are some temperament impressions too

• blackwood – jazzy, dirty, trippy barbershop pole effects
• machine – sparkly, pure, unusual
• mavila – face swap, expectation and surprise
• porcupine – an otonal- and Arabian- influenced diatonic without being either of those things

What are your own impressions?

The British Library sound archive seeks to collect sound recordings that can be preserved for generations to come. They are home to one of the largest collections of vinyl recordings in the world. They also curate a library of digital recordings. The collection includes not just music but also drama, literature, field recordings, and oral history.

A representative from the library reached out to ask if I would donate some of my recordings to the sound archive. Of course I was happy to do that. It’s fun to wonder what some futuristic person would think if they discovered early 2000s xenharmonic bangers.
