Unbolted Frontiers

In the past couple of years, I've gotten back into composing music after a fifteen year break. I had originally stopped making music without any expectation that I'd ever do it again. Making music had become extremely stressful due to two factors: economics, and proprietary software. Briefly, I'd assumed that I needed to make money from music because I believed I had no other skills. This lead to a very fear-driven and unpleasant composition process more suited to producing periodic mild mental breakdowns than listenable music. Additionally, all of the software I was using to make music was the standard vendor lock-in proprietary fare; That's a nice studio you have here, it'd be a shame if you stopped paying thousands of monetary units per year to keep it working exactly the same way it always has and something happened to it... What? You want to use some different software and migrate your existing data to it? Ha ha ha! You're not going anywhere!

So I gave up and got into software instead. Fast forward fifteen years and now, as a (presumably) successful self-employed software engineer and IT consultant, economics are no longer a factor. Additionally, after fifteen years of using, contributing to, developing, and publishing open-source software, coupled with huge advances in the quality of all of the available open-source music software - I no longer have any desire or use for proprietary audio software. There is nothing that any proprietary audio software vendor can offer me that I could conceivably want.

As I mentioned, my music composition process in the distant past had been very fear-driven, and I'd accumulated a ton of rather destructive mental habits. However, fifteen years of meditation and other somewhat occult practices have left with me the tools needed to recognize, identify, and extinguish those mental habits.

One habit that I identified very early turned out to be one that was common amongst other musicians I know. Specifically: Too much detail too soon. In essence, it's very easy in modern electronic music composition environments to write four bars of music (looping the music continuously as you write), and progressively add more and more detail to the music, and do more and more tuning and adjustments to the sounds. Before long, eight hours have passed and you have four very impressive bars of music, and no idea whatsoever as to what the next four bars are going to be. Worse, you've essentially induced a mild hypnotic trance by listening to the same section of music over and over, and have unconsciously cemented the idea into your mind that these four bars of music are going to be immediately followed by the same four bars. Even worse; you've almost certainly introduced a set of very expensive (in terms of computing resources here, but perhaps in terms of monetary cost too, if you're that way inclined) electronic instruments and effects in an attempt to get the sound just the way you like it, and you may now find that it's practically impossible to write any more music because the amount of electronic rigging has become unwieldy. If you're especially unlucky, you may have run out of computing resources. Better hope you can write the rest of the music using only those instrument and plugin instances you already have, because you're not going to be creating any more!

Once I'd identified this habit, I looked at ways to eliminate it before it could manifest. I wanted to ensure that I'd written the entirety of the music of the piece before I did any work whatsoever on sounds or production values. The first attempt at this involved painstakingly writing out a physical score in MuseScore using only the built-in general MIDI instruments. The plan was to then take the score and recontextualize it using electronic instruments, effects, et cetera. In other words, the composition would be explicitly broken up into stages: Write the music, use the completed music as raw MIDI input to a production environment, and then manipulate the audio, add effects, and so on to produce a piece that someone might actually want to listen to. As an added bonus, I'd presumably come away with a strong understanding of the music-theoretic underpinnings of the resulting piece, and I'd also be forced into making the actual music itself interesting because I'd not be able to rely on using exciting sounds to maintain my own interest during the composition process.

The result was successful, but I'd not try it again; having to write out a score using a user interface that continually enforces well-formed notation is far too time consuming and makes it too difficult to experiment with instrument lines that have unusual timing. MuseScore is an excellent program for transcribing music, but it's an extremely painful and slow environment for composition. In defense of MuseScore: I don't think it's really intended for composition.

Subsequent attempts to compose involved writing music in a plain MIDI sequencer on a piano roll, but using only a limited number of FM synth instances. Dexed, specifically. These attempts were mostly successful, but I still felt a tendency to play with and adjust the sounds of the synthesizers as I wrote. The problem was that the sounds that Dexed produced were actually good enough to be used as the final result, and I was specifically trying to avoid doing anything that could be used as a final result at this stage of the composition.

So, back to the drawing board again. I reasoned that the problem was down to using sounds that could conceivably appear in the final recording and, quite frankly, being allowed any control whatsoever over the sounds. An obvious solution presented itself: Write the music using the worst General MIDI sound module you can find. Naming no names, I found a freely-available SoundFontⓡ that sounded exactly like a low-budget early 90s sound module. Naturally, I could never publish music that used a General MIDI sound module with a straight face. This would ensure that I wrote all the music first without any possibility of spending any time playing with sounds and then (and only then) could I move to re-recording the finished music in an environment that had sounds that I could actually tolerate.

Attempts to compose music in this manner were again successful, but it became apparent that General MIDI was a problem. The issue is that General MIDI sound modules attempt to (for the most part) emulate actual physical acoustic instruments. This means that if you're presented with the sound of a flute, you'll almost certainly end up writing monophonic musical lines that could conceivably be played on a flute. The choice of instrument sound inevitably influences the kind of musical lines that you'll write.

What I wanted were sounds that:

  • Sounded bad. This ensures that the sounds chosen during the writing of the music won't be the sounds that are used in the final released version of the piece.

  • Sounded different to each other. A musician who's opinion I respect suggested that I use pure sine waves. The problem with this approach is that once you have four or five sine wave voices working in counterpoint, it becomes extremely hard to work out which voice is which. I need sounds that are functionally interchangeable and yet are recognizably distinct.

  • Sounded abstract. I don't want to have any idea what instrument the sound is supposed to represent. It's better if it doesn't represent any particular instrument; I don't want to be unconsciously guided to writing xylophone-like or brass-like musical lines just because the sound I randomly pick sounds like a xylophone or trumpet.

  • Required little or no computing resources. I want to be able to have lots of instruments without being in any way concerned about computing resource use. Additionally, I don't want to deal with any synthesizer implementation bugs during composition.

Reviewing all the options, I decided that the best way to achieve the above would be to produce a custom SoundFontⓡ. There are multiple open source implementations available that can play SoundFontⓡ files, and all of them are light on resource requirements and appear to lack bugs. I wanted a font that contained a large range of essentially unrecognizable sounds, all of which could be sustained indefinitely whilst a note is held. There were no existing tools for the automated production of SoundFontⓡ files, so I set to work:

  • jsamplebuffer provides a simple Java API to make it easier to work with buffers of audio samples.

  • jnoisetype provides a Java API and command-line tools to read and write SoundFontⓡ files.

I then went through hundreds of Dexed presets collected from freely-available DX7 patch banks online, and collected 96 sounds that were appropriately different from each other. I put together some Ardour project files used to export the sounds from Dexed instances into FLAC files that could be sliced up programatically and inserted into a SoundFontⓡ file for use in implementations such as FluidSynth.

The result: Unbolted Frontiers.

A SoundFontⓡ that no sensible person could ever want to use. 96 instruments using substandard 22khz audio samples, each possessing the sole positive quality that they don't sound much like any of the others. Every note is overlaid with a pure sine wave to assist with the fact that FM synthesis tends to lead to sounds that have louder sideband frequencies than they do fundamental frequencies. All instruments achieve sustain with a simple crossfade loop. Hopefully, none of the instruments sound much like any known acoustic instrument. The only percussion sounds available sound like someone playing a TR-808 loudly and badly.

If I hear these sounds used in recorded music, I'm going to be very disappointed.

A Low Budget Render Farm

I do a bit of 3D rendering now and then using Blender. Blender has multiple rendering engines: Blender Internal and Cycles. Blender Internal is a 1990s style CPU-based raytracer, and Cycles is a physically-based renderer that can be executed on either CPUs or GPUs. Cycles is technologically superior to Blender Internal in every way except for one: The performance when running on CPUs is essentially hopeless. In order to get reasonable render times, you really need a powerful GPU with an appropriate level of driver support. I refuse to use proprietary hardware drivers for both practical reasons and reasons of principle. This has meant that, to date, I haven't been able to use Cycles with GPU acceleration and have therefore stuck to using Blender Internal. As I don't aim for photorealism in anything I render (I prefer a sort of obviously-rendered pseudo-impressionist style), Blender Internal has been mostly sufficient.

However, I've recently moved to rendering 1080p video at 60fps. This means that even if it only takes ~10 seconds to render a single frame, that's still about 35 hours of rendering time to produce a 3.5 minute video.

I have a few machines around the place here that spend a fair amount of time mostly idle. I decided to look for ways to distribute rendering tasks across machines to use up the idle CPU time. The first thing I looked at was netrender. Unfortunately, netrender is both broken and abandonware. I spent a good few hours spinning up VM instances and trying to get it to work, but it didn't happen.

I've been using Jenkins for a while now to build and test code from hundreds of repositories that I maintain. I decided to see if it could be useful here... After a day or so of experimentation, it turns out that it makes an acceptable driver for a render farm!

I created a set of nodes used for rendering tasks. A node in Jenkins speak is an agent program running on a computer that accepts commands such as "check out this code now", "build this code now", etc. I won't bother to go into detail on this, as setting up nodes is something anyone with any Jenkins experience already knows how to do. Nodes can be assigned labels so that tasks can be assigned to specific machines. For example, you could add a linux label to machines running Linux, and then if you had software that would only build on Linux, you could set that job to only run on nodes that are labelled with linux. Basically, I created one node for each idle machine here and labelled them all with a blender label to distinguish them from the nodes I use to build code.

I then placed my Blender project and all of the required assets into a Git repository.

I created a new job in Jenkins that checks out the git repository above and runs the following pipeline definition included in the repository:

#!groovy

// Required: https://plugins.jenkins.io/pipeline-utility-steps

node {
  def nodes = nodesByLabel label:"blender"
  def nodesSorted = nodes.sort().toList()
  def nodeTasks = [:]
  def nodeCount = nodesSorted.size()
  for (int i = 0; i < nodeCount; ++i) {
    def nodeName = nodesSorted[i]
    def thisNodeIndex = i

    nodeTasks[nodeName] = {
      node(nodeName) {
        stage(nodeName) {
          checkout scm
          sh "./render.sh ${thisNodeIndex} ${nodeCount}"
        }
      }
    }
  }
  parallel nodeTasks
}

This uses the pipeline-utility-steps plugin to fetch a list of online nodes with a particular label from Jenkins. I make the simplifying assumption that all online nodes with the blender label will be participating in render tasks. I assign each node a number, and I create a new task that will run on each node that runs a render.sh shell script from the repository. The tasks are executed in parallel and the job is completed once all subtasks have run to completion.

The render.sh shell script is responsible for executing Blender. Blender has a full command-line interface for rendering images without opening a user interface. The main command line parameters we're interested in are:

blender \
  --background \
  coldplanet_lofi.blend \
  --scene Scene \
  --render-output "${OUTPUT}/########.png" \
  --render-format PNG \
  --frame-start "${NODE_INDEX}" \
  --frame-end "${FRAME_COUNT}" \
  --frame-jump "${NODE_COUNT}" \
  --render-anim

The --frame-start parameter indicates at which frame the node should start rendering. The --frame-end parameter indicates the last frame to render. The --frame-jump parameter indicates the number of frames to step forward each time. We pass in the node index (starting at 0) as the starting frame, and the number of nodes that are participating in rendering as the frame jump. Let's say there are 4 nodes rendering: Node 0 will start at frame 0, and will then render frame 4, then frame 8, and so on. Node 1 will start at frame 1, then render frame 5, and so on. This means that the work will be divided up equally between the nodes. There are no data dependencies between frames, so the work parallelizes easily.

When Jenkins is instructed to run the job, all of the machines pull the git repository and start rendering. At the end of the task, they upload all of their rendered frames to a server here in order to be stitched together into a video using ffmpeg. Initial results seem promising. I'm rendering with three nodes, and rendering times are roughly 30% of what they were with just the one node. I can't really ask for more than that.

There are some weaknesses to this approach:

  1. Rendering can't be easily resumed if the job is stopped. This could possibly be mitigated by building more intelligence into the render.sh file, but maybe not.

  2. Work is divided up equally, but nodes are not equal. I initially tried adding a node to the pool of nodes that was much slower than the others. It was assigned the same amount of work as the other nodes, but took far longer to finish. As a result, the work actually took longer than it would have if that node hadn't been involved at all. In fact, in the initial tests, it took longer than rendering on a single node!

  3. There's not really a pleasant way to estimate how much longer rendering is going to take. It's pretty hard to read the console output from each machine in the Jenkins UI.

Finally: All of this work is probably going to be irrelevant very soon. Blender 2.8 has a new realtime rendering engine - EEVEE - which should presumably mean that rendering 3.5 minutes of video will take me 3.5 minutes.

In his own words:

... the binaries there are very volatile by nature, many rotate daily, so hooking them up to something more or less permanent would be problematic.

Expect to have to run repository-update urn:net.shipilev.builds every day if you use the repository!

Lurking Between Releases

A while back, I talked about moving to the bndtools suite of Maven plugins in preference to the Felix bundle plugin. The reason for this is better cross-IDE compatibility: Eclipse only really works with bndtools, whilst Intellij IDEA only really works with the Felix maven-bundle-plugin. This means that the plugin you choose to use in your Maven project ends up dictating which IDE developers must use in order to work with it. That's not great! However, I discovered that Intellij IDEA could be configured to use the OSGi manifest file that the bndtools Maven plugin creates, and therefore that means that developers can use either IDE as long as I use the bndtools plugins in my own projects.

Unfortunately, upon switching to the bndtools plugin in the primogenitor, I soon ran into MNG-6059 and MNG-5951. Briefly, Maven has some baked-in behaviour that is intended to produce metadata that follows the conventions people used when everyone used SVN to manage source code. However, those conventions result in Maven producing metadata that's essentially incorrect with regards to modern conventions. Specifically, Maven will automatically append module names to URIs specified in your project, because it assumes that you've laid out files in a particular way on remote servers. This automatic name appending could not previously be turned off. However, Maven 3.6.0 provided support for some attributes that you could place into your pom.xml files that would disable this automatic appending. Additionally, 3.6.0 comes with numerous fixes for working with Java 11 bytecode. As I recently decided that Java 11 was the new minimum version that I was going to support, 3.6.0 is really a requirement moving forward.

Unfortunately, this has now lead to further problems! One problem is that it's not possible to push a pom.xml file containing the new attributes to Maven Central because the version of Nexus running on Central can't parse the new POM files yet. The second problem is that the attributes are not inherited. I currently have over 850 pom.xml files spread over close to a hundred projects. There's just no way I'm going to edit each and every pom.xml file and add those attributes by hand. I want to specify them once in the primogenitor and have them apply everywhere. I've raised both points on the Maven mailing list, and my cries have been heard. All of this will hopefully be fixed in 3.6.1.

After all is said and done, this means that I can't start moving projects to Java 11 just yet or even do a full 3.0.0 release of the primogenitor because I need Maven 3.6.1 to do so. I wasn't available to test 3.6.0 much before it was released, but I can do plenty of testing for 3.6.1. It looks like I'll temporarily be in limbo for a couple of months!
