FLTRS-LE

Free

One legendary filter circuit. Fully unlocked.

The one we chose is EUROPA-6 — our take on the Roland Jupiter-6 filter. Not modeled. Reconstructed. Most filter plugins model the sound of a circuit; EUROPA-6 models the circuit itself — OTA gain stages, SVF topology, component tolerances, and the subtle nonlinearities that make a Jupiter-6 feel alive rather than just filtered. We also pushed it past the hardware: negative resonance, parallel band-split path, stereo detune, and vintage aging drift. The Jupiter-6 filter has a quality where the resonance snarls but never loses control — bold sweeps that stay usable no matter how hard you push them.

FAQ

Before you install.

Is FLTRS a synthesizer? Does it generate its own sound?

FLTRS is an audio effect plugin, not a standalone synthesizer that generates sound via MIDI. It is designed to process your existing audio. By chaining the circuits and physics engines together, it turns your DAW into a much more performable synthesis environment.

Does this require an iLok or physical USB dongle?

No. FLTRS authorizes with your MNTRA account—no dongles or iLok.

Is FLTRS fully compatible with Apple Silicon and Windows?

Yes. Apple Silicon and Intel Macs (macOS 10.11+), and Windows 10+—VST3, AU, and AAX.

Is this just another mixing EQ like FabFilter?

EQs correct. FLTRS is a creative filter instrument—identity, motion, and analog-style push when you lean on it.

I want to chain 3 or 4 instances. Will this melt my CPU?

That’s how it was meant to be used—lean enough to sit between reverbs, delays, and buses in a real session.

What happens after checkout?

Your download and license are attached to your MNTRA account immediately after checkout. FLTRS includes Mac + Windows installers in VST3, AU, and AAX formats.

Why does FLTRS-LE use checkout if it is free?

FLTRS-LE is $0, but checkout attaches the download and license to your MNTRA account so you can access it again later.

What is the 30-day money-back guarantee?

Try FLTRS in your own sessions. If it doesn’t feel right for your workflow, email support@mntra.io within 30 days of purchase and we’ll help you with a refund.
