[OC] Powerful additive/spectral VST synth "Spektral" (Beta/Demo)
Hey! I'm Jaron Sweder, a music producer and software developer. I have been working on this incredibly powerful additive/spectral VST synth called "Spektral" for the past 2 years. It's still in beta, but it's finally at a stage where I can get other people to play around with it.
The little demo video shows a simple EDM bass and some simple drums. But this synth is also great for percussion, complex ambiences, and you can even use it as a vocoder using the sidechain input.
The core of this synth is a 'spectral table'. This is a 512x512 table of spectral data. You can load an audio sample into this, or even an image. This data can then be manipulated and modulated in many different ways. And eventually it will end up interacting with 1 of 3 'spectral parameters'. For the default 'Additive' mode, these parameters are level, frequency, and phase. This means you get precise control over the level, frequency, and phase of all individual 576 partials that are generated in the 'Additive' mode. There's also a 'Resonator' mode, which is a bank of 512 resonators, where you get control over the level, frequency, and decay time of each individual resonator. This mode approaches physical modeling, and with a bit of messing around you can make organic sounding real instruments. And because it's all coming from these spectral tables, you can make it as simple or as complicated as you want. You can just load a random sample into it and mess around. Or craft a very specific 512x512 image file to do exactly what you want. It's also very easy to make variations of the same sound, just load a different sample into the table! Check the user manual for more information, which can be found in the link below.
The demo is available for MacOS and Windows, both downloads can be found on this page, as well as a link to the user manual. It also comes with a handful of presets to play around with that show what it's capable of: https://shop.kaixo.me/product/Spektral

DISCLAIMER: I want to be clear that this is a demo version, it will not save its state, and you cannot export audio from your DAW in this version. Unfortunately, given how much time I've put into this insanely powerful and highly optimized synth, I can't afford to make it available for free. Hence the limitations. I know this sucks, and if I didn't need the money I'd make it free in an instant. But such is life...
