Sjoerd van Kreel releases InfernalSynth, a freeware semi-modular synthesizer VST3 plugin for Windows.
As a VCV Rack enthusiast, complicated synths are always exciting. There’s something about a slew of purpose-driven controls over every possible parameter that can inspire just as ably as the refined control set of the Roland Juno 106.
InfernalSynth falls firmly in the former’s camp, bringing together a variety of elements to give a deeply controllable synth with a lot of fun options.
InfernalSynth First Impressions
InfernalSynth’s interface comes across as a more sedate sibling to HrastProgrammer’s Tranzistow; there are a lot of controls present.
There are four oscillators to use with InfernalSynth, and they have a variety of modes for a good bit of diversity in sound generation.
Basic presents your bog standard waveforms. Mix can blend different waveforms, using standard analog waveforms to create more harmonically complex waves. DSF is an interesting one that uses distinct algorithms to make complex waveforms.
Oscillators can be tuned, synced, and have FM applied. So quite a few possibilities with just a single oscillator, let alone four of them.
Filtering is another subject entirely, with two distinct modes on offer. Users can select a state variable filter or a comb filter, and each has multiple variations for sculpting your sound around.
The signal path is wide open on InfernalSynth, and you can route audio anywhere you want between the four oscillators and twenty effects modules.
Effects are somewhat limited in scope, offering up filtering, reverb, delay, and a waveshaper. Having twenty slots allows for some creative design, however.
InfernalSynth TLDR And Specs
InfernalSynth is an impressively designed synth that is perhaps not for the faint of heart.
The core sound of the oscillators and filters is quite nice, and you have quite a bit of flexibility in how you approach designing a sound. You can also apply the intense effects sections and a plethora of modulators to other sounds, thanks to the inclusion of an FX version of the plugin.
This article only scratches the barest of surfaces of the possibilities of the synth.
InfernalSynth is, unfortunately, Windows-only and requires a 64-bit host. The only plugin format provided is VST3.
