"I really love the approach of Vostok Instruments where they’re building out modules that not only sound great, but that offer multiple channels of the same functions. In modular you often need more, and not particularly more variety, but more of the same functions to push creativity and deeper levels of patching.
Atlas is a set of 4 multimode filters (low pass, high pass, band pass), with clever normalisations, dual modulation inputs per channel, a ‘classic synths of Japan in the 80s’ inspired sound PLUS you get an interpolating scanner bank that will morph between the four filter outputs. It’s an impressive thing that’s been a delight to play and patch with.
As always I hope the video provides you patches to explore Atlas and other filters and functions in your own systems."

Mini press release follows:
"Atlas is the latest addition to our range of multi-channel modules, a fully analog, four-channel multimode filter.
The cores are a modern approach to the gain-cell-based filters included in many of the classic Japanese synths of the 80s, with a vastly improved dynamic range, a super-accurate resonance compensation circuit, and a clean self-oscillation. It is perfect for recreating iconic TR-drum sounds by pinging the filters with fast envelopes or triggers.
In addition to the four filters, the module counts with a dedicated Interpolating Scanning Circuit that morphs between all the filter outputs to create new shapes and timbres."
User Manual
Additional details via Vostok Instruments:
When we talk about the sound signature of synths, filters are probably one of the first topics appearing.
On Atlas, we dive into the sound of the 80s Japanese classics with four gain-cell-based multimode filters that keep the silky and creamy sound of those legendary machines along with some technical improvements like a better noise floor, an accurate resonance compensation, and a daisy-chain input implementation that makes some patching techniques like parallel filtering a lot easier.
The filter cores have been carefully designed and tweaked to be pristine without losing character. With three filter modes available per channel, 4p-LP, 2p-HP, and 4p-BP, Atlas can cover almost any filtering technique, from superb filter sweeps to multi-slope resonant patches.
Thanks to its precise resonance circuit, each core creates a clean sine wave when self-oscillating. Excite the inputs with fast trigger or gate signals, and you will get TR-like drum sounds, from deep kickdrums to nice toms and congas.
In addition, the module counts with a CV-controlled Interpolating Scanner circuit that morphs softly between each filter output, creating new shapes and timbres as it fades between the channels.
