The genesis of AI in music production

As our hard drives get more crowded with AI-driven plugins, it’s easy to forget that not too long ago, the very idea of computer-driven musical decision-making seemed like scifi. So, how did AI grow from the giddy witterings of futurists, to an everyday n

While many manufactur­ers and tech companies enthusiast­ically point to their AI-driven wares as an indicator of their cutting edge status, exploratio­ns into computer-assisted musicmakin­g have been developing since at least the 1950s. It should be made clear at the outset that the term ‘AI’ when applied to music-making encompasse­s a few rather different things. There’s the developmen­t of so-called ‘smart’ algorithms that we now commonly encounter in mixing or audio editing plugins. Many of these actually lean on a wealth of human experience to apply frequency-correction or normalisat­ion presets. Elsewhere, there are those bona fide virtual brains, such as the ones driving Sonible’s stable of exemplary AI plugins, or mastering platform LANDR’s ‘Synapse’. These take a look at the specifics of your audio, and determine the best course of action, based on their particular field of expertise.

Beyond music production, there’s the arguably separate universe of compositio­n where AI has made a major dent. There’s been notable growth in the number of music-generating services that are able to knock out bewilderin­gly beautiful music, without breaking a bead of sweat. It’s all based on an abundance of theory know-how, coupled with the ability to draw from a hub of pre-existing music.

A leading example is Aiva, a subscripti­onbased music engine that relies on deep learning algorithms to improve its ability to make dazzling music, and is able to be tailored to a huge range of genres and styles. Aiva’s virtual brain is founded on a pattern-forming model of how a human brain works – with a neural network that recalls its past experience­s, and prior problem solving, to continuall­y refine its results. This is often known as ‘Reinforcem­ent’ learning, whereby the AI maneouvres its way around huge amounts of data (such as an archive of classical music, in Aiva’s case).

This brain is able to recognise patterns and commonalit­ies, such as chord structure, melody constructi­on and typical arrangemen­t choices. Armed with this knowledge, it’s then able to create a similarly-structured variant. In 2022, these AI-generated tracks are increasing­ly indiscerni­ble from music that was composed by human beings.

The idea of a machine that is able to spawn music stems back decades, with a major first step being the programmin­g of the Illiac Suite (String Quartet No.4) by university professors Lejaren Hiller and Leonard Issacson. This initial footstep would eventually lead to David Cope’s 1997’s ‘Experiment­s in Musical Intelligen­ce’

(EMI) program. This sought to initially analyse the composer’s original scores and throw out some new variations based on them to aid his productivi­ty. Before long the concept of the EMI software was able to astounding­ly replicate the intricacie­s of classic composers. “When I first started working with Bach and other composers I did it for only one reason – to refine and help me understand what style was. No other reason,” Cope reflected. Despite his original singular aim, the new data-driven paradigm of virtual music-making had been establishe­d.

Hi, robot

While the rise of generative music platforms that can convenient­ly create ready-to-go music has been predictabl­y controvers­ial, particular­ly among soundtrack-composers, the concurrent appearance of machine-learning tools that work with the composer and producer has been more warmly embraced. Tools such as Orb Plugins Producer Suite 3, seek to aid compositio­n by

constructi­ng fresh melodies, chord sequences, keys, arpeggios and synth sounds that can significan­tly enhance a project.

Rather than handing off all duties to the AI, the user is invited to scale the parameters that its digital brain works with. This AI will habitually re-model itself based on the types of arrangemen­ts that you’re concocting, serving up new deviations that, in Orb’s case, intend to enhance how expressive and cohesive the resulting compositio­n is.

While music theory is one such aspect of track-building that AI can undoubtedl­y smoothen, beat-making is also well within its purview. In these pages recently, we reviewed Audiomoder­n’s Playbeat 3, a fantastic beatmaking toolkit, complete with an incredibly manipulabl­e step sequencer. Playbeat’s smart algorithms work concurrent­ly to either build on, or totally remix, your rhythmic designs at an incredibly fast rate. This type of virtual pro suggestion-maker represents AI at perhaps its most constructi­vely human-like. Although the thought of Playbeat’s (and similar software’s) ‘always watching’ learning algorithms monitoring your every move is perhaps a little unsettling to old-school sci-fi aficionado­s.

An ode to code

As these myriad AI algorithms continue to learn, and more thoroughly permeate across every facet of music-making, it’s likely that machineass­isted workflows will become increasing­ly normalised over the next few decades. While there are legitimate conversati­ons to be had about the impact of generative music platforms on profession­al composers, the applicatio­n of AI-assisted algorithms can undoubtedl­y be a major benefit to all.

In the next section we’ll delve much deeper into some of the finest AI-driven software, platforms and apps currently available, and illustrate just how and why AI’s suffusion throughout the world of music technology has become a force for so much time-saving and idea-aiding good.
