Atlantis
Key Features
- Three true stereo morphing oscillators with independent width, phase, spread, chorus, tuning, volume, envelope, and panning controls
- Dual configurable filter banks with standard and proprietary filter algorithms, plus a dedicated waveshaper section
- Room-modelling multi-tap filtered delay system with its own pair of selectable filters for complex spatial effects
- Complete modulation freedom — every slider parameter can be driven by LFOs, envelopes, MIDI CC, note, velocity, or signal follower in any combination
- Custom waveform import via WAV files, automatically upsampled into high-resolution wavetables for oscillators and LFOs
- Flexible signal routing with switchable filter and shaper configurations for creative patch design
- Includes Atlantis Filter Delay as a separate VST effect plugin for processing external audio through the same filter and delay engine
Description
Atlantis by Jeremy Evers is a hybrid synthesizer and effect processor that packs modular-level sound design into a single plugin. It ships as two components: Atlantis Synthesizer (VSTi) and Atlantis Filter Delay (VST effect), giving you both an instrument and a standalone multi-filter delay processor.
At its core sit three true stereo morphing oscillators, each with independent controls for width, phase, spread, chorus, tuning, volume, envelope, and panning. These feed into dual configurable filters with both standard algorithms and unique proprietary designs, a waveshaper section, and a room-modelling multi-tap delay with its own pair of selectable filters.
What sets Atlantis apart from most synths is its depth of modulation. Every slider in the interface can be controlled by any combination of LFOs, envelopes, MIDI CC data, note pitch, velocity, and a signal follower.
Long-time users praise its modulation flexibility and signal quality, noting that features like waveform morphing predate similar capabilities found in modern commercial synths. You can import any WAV file as a custom waveform for oscillators and LFOs, with samples automatically upsampled into high-resolution wavetables.
The synth supports polyphonic, monophonic, portamento, and arpeggio play modes. A skinnable interface, a large preset collection, and the bundled Filter Delay effect plugin round out the package.
Atlantis is Windows-only, available in 32-bit and 64-bit VST format. The current version is 0.9s, which addressed MIDI note lockup bugs and improved the key tracking module.

Frequently Asked Questions
Does Atlantis work on macOS or Linux?
No. Atlantis is Windows-only, available as a 32-bit and 64-bit VST plugin. There is no macOS, Linux, or AU/AAX version. If you need a cross-platform alternative with similar depth, look at synths like Vital or Surge XT.
What is Atlantis Filter Delay and how is it different from the synth?
Atlantis Filter Delay is a separate VST effect plugin included in the download. While the Atlantis Synthesizer generates sound internally, the Filter Delay processes external audio through the same dual-filter and multi-tap delay engine. You can use it on any track in your DAW as an insert effect.
Can I load my own waveforms into Atlantis?
Yes. Drop any WAV file (stereo or mono, any sample rate or bit depth) into the waveforms folder, and Atlantis will upsample it into a high-resolution wavetable. These custom waveforms can be used for both oscillators and LFOs, dramatically expanding the synth's sonic palette.
Is Atlantis still being updated?
The most recent version is 0.9s, released in 2020, which added 64-bit support and fixed MIDI note lockup bugs. While updates are infrequent, the developer's website remains active and the download links are working. The synth is stable for production use in its current state.
