Obviously, I have picked up a few new DSP tricks over these 15 years since version 1. Magnus: I aimed for version 2 to be fully backwards compatible, so I kept the fundamental design similar to version 1, but I did overhaul most of the DSP. What’s going on inside the new engine – and why does it sound richer than Synplant 1? The synth engine of Synplant is designed to produce interesting results when you mutate its parameters, and I believe that makes many of those early half-random solutions fun. If you haven’t already watched Cuckoo’s interview with me, I can recommend checking out these two chapters:Ĭoncerning weird and disconnected results, there are “confidence” parameters for these machine learning algorithms that I have chosen to keep relatively low, meaning that it will start with pretty wild guesses. The training takes months for an optimized small net that can run locally on your CPU, and every second that it trains, it plows through hundreds of settings. The amount of data that it trains on is *massive*. I train them on semi-random sounds generated by the synth itself so that it learns how to go backward from output sound to input parameters. For the last five years, I focused mainly on designing and improving the neural nets involved. It’s a combination of different machine-learning algorithms that I have tweaked over a period of 10 years. I can say that, without a doubt, Genopatch is the most challenging endeavor I have ever undertaken. How did you work on training the machine learning? What was the corpus you trained on – and how does it work, especially as sometimes the weirdest results are the most satisfying? Here’s Magnus on how that grew from 2009’s seeds. All the onboard machine learning and DSP and heuristics and UI details are about morphing and mutating sounds into something you’ve never heard before. It’s not about making predictable, sound-alike results. This is not the dumbed-down tech we’re seeing elsewhere. The secret to that engine is that it is full of both surprise and personality. Synplant’s creator and Sonic Charge Magnus Lidström has been really busy since 2009, and not only on Synplant’s technological reimagining. So here are some more insights from Magnus Lidström about how the original 2009 Synplant led to 2023’s Synplant-further-out follow-up. It’s weirder than ever, from top to bottom. Now it has AI-powered sonic analysis and generation which – can sound completely glitchy and unexpected. Synplant 2: it’s still leafy and organic – just more so.
