John Moriarty, a member of the global xenharmonic/microtonal music movement, has been making videos to explain modern tuning theory concepts. The ideas are presented in a very visual way with narration and musical examples. I would be interested to know how tuning theory newbies get on with these vids. It’s a heavy topic, both wide and deep with details. Anyway, enjoy John’s playlist!
And I’m sure there’s more to come in the future.
Here’s something new from the Dubbhism Netlabel, a naughty lil’ instrumental album called Deep by the demented dub scientist Tony Dubshot. Sometimes I get the appetite for trippy electro dub, and Deep has got me feeling full right now.
Actually Deep is the instrumental counterpart to the 6-track EP High that is set to come out soon, featuring Sarah Winton, MK-Ultra and I-Lo. I can’t wait to hear that one when it drops. (September 8th – digital stores)
Until that time comes, let’s dive down to the depths of Deep. It’s a 42 minute spin out across 10 tracks, which blend together into one oceanic ODDyssee. All united by profoundly bassy bass, and dripping wet with analog dubbiness.
Good Morning Sunshine and Mixup kick off the journey, both tracks bringing jolly vibes and a wobbly kind of sound.
From Madd Science, the album goes into a phase of space-faring utopia jams. That segue between Aura and The Capricorn Speaks!!! Can’t get enough. This is like a story told in dub.
Every track on the album seems to directly lead to the next with no gaps. The effect is like listening to a DJ set, only the transitions are totally abrupt. It works surprisingly well and keeps the whole playlist shuffle-proof.
You’re a Fish sounds like flipped out Crash Bandicoot music. Then comes Soul Fire—I caught the vocal version of this track on the radio, featuring Sarah Winton from the forthcoming High EP, and loved its funky, steadfast groove with all the stops and starts.
United in Battle… I subconsciously make screw faces as the descending bassline rips through me. Also, there’s something distinctly fresh about this. Ah that’s right, Tony Dubshot is in the know about the art of xen (aka microtonal music). A few years ago I wouldn’t have guessed that any music could sound alien yet funky, at least in the same way this does.
Knock knock… I almost can’t take it, this is too low. My brains are trying to break out of their monkey skull prison. Just like the previous track, Knock Knock is xen, owing to its tropical punch. Deep reaches a chill conclusion with Anti-Matter.
I’m deeply impressed over here. Dubshot is raising the bar higher for himself with his every release. Get this freebie album immediately and listen for yourself.

Those of you who have built synths in Max/MSP or Max 4 Live will have used the mtof (MIDI-to-frequency) object. This clever little object waits for you to send it a MIDI note number (0-127), then it spits out a frequency (Hz). Perfect if you’re working within the confines of 12-tone equal temperament—or rather limiting if you wish to use all kinds of expressive intonation systems outside of the Western common practice.
There is a very simple way to get microtonal scales out of your Max/MSP synths. We simply replace the mtof object with coll.
Coll can be used to store and edit collections of data. The data is stored in a text file. Each item of data contains an index followed by some content. For example, we could use coll to remember the release years for various killer synths.
Above, the coll object is waiting to receive an index (either YamahaDX7 or Theremin) before it spits out the data we want. I just clicked the “YamahaDX7” button, so “1983” was sent via the first outlet of coll.
To see and edit all the data inside the coll, just double-click on the coll object. It will bring up the data entry window. Here’s what’s inside the above coll object:
OndesMartenot, 1928; RolandTB-303, 1982; Theremin, 1920; YamahaDX7, 1983;
Neat trick. Mind you it’s not very useful for our goal of exploring crazy scales.
Here’s how we can use coll as a replacement for mtof. First we need to understand our data structure. We send a MIDI note number (0-127) to the coll object. We want coll to spit out a frequency in Hz. So we double click coll, and we start inputting data for what frequency corresponds to what MIDI note number.
# Lines that start with a # symbol are comments. # This is a simple scale which starts at 100 Hz on MIDI note 0. 0, 100.0; 1, 200.0; 2, 300.0; 3, 400.0; 4, 500.0; 5, 600.0; 6, 700.0; ... 127, 12800.0;
To test this out, let’s send the number 0 to the coll. This is the lowest possible MIDI note number, and according to our data we should receive the float value 100.0 from coll’s first outlet.
A success! It’s pretty simple to get it to work, but the only problem is that the tuning data took us a looooong time to type… 128 lines in total! Luckily coll can read .txt files, and there is a much better way to generate tuning data in this format. For this tutorial, we’ll be using Scala tuning software to create .txt files that coll can read.
First create or load some tuning data into Scala. (For now we’ll just load a file from Scala’s huge database)
Then type the following command into Scala:
set synth 135
Scala will say “Synthesizer 135: Max/MSP coll data, via text file”. You’re doing just great.
Now click File → Export synth tuning as shown below.
This will bring up a familiar save file dialog, and you can save your .txt file anywhere. Once your .txt file is saved somewhere convenient, your can load it into your coll object.
Create a message button which contains the word “read”. Connect this up to the coll object (as shown below). You can click the “read” button to bring up an open file dialog. Use this to load the file you just exported from Scala.
Once you’ve loaded the .txt file into coll, you can check that the data went in correctly by double-clicking the coll object.
# Tuning file for Max/MSP coll objects created by Scala # # Sean "Sevish" Archibald's "Trapped in a Cycle" JI scale 0, 8.1757989; 1, 8.4312926; 2, 9.1977738; 3, 9.5384321; 4, 10.2197486; 5, 10.7307361; 6, 11.2417235; 7, 12.2636984; ...
Congrats, you’ve just replaced the mtof object with your very own, microtunable coll! Enjoy playing microtonal scales in Max/MSP.
Big up to Manuel Op de Coul, the creator of Scala, who added support for Max/MSP coll files on my request. Much appreciation that his project is still being maintained.
Ever wondered how to get various software synthesisers to play microtonal scales? A while ago I added a lot of info about this to the Xenharmonic Wiki. Summarised below.
Many software plugins (VST, AU, RTAS etc.) allow you to create microtonal music. Not all of them, though. The ones that do mostly accept tuning data by one of the following methods:
