This is Push and Groove’s inaugural release, and you can download FILTRONIX directly from their website for free—no sign-up required. The plugin is fully royalty-free for personal and commercial projects.
Authentic Analog Circuit Modeling
FILTRONIX uses ZDF (Zero-Delay Feedback) technology to deliver realistic analog filter behaviour. Each of the four onboard filter types is based on a classic analog synth design:
- M-Filter (Transistor Ladder): Faithful to a renowned ladder filter for warm character and resonance.
- S-Filter (OTA): Based on an operational transconductance amplifier, smooth and versatile.
- D-Filter (Diode Ladder): Punchy response and aggressive tonality.
- C-Filter (State Variable): Flexible shapes with clean resonance and multiple modes.
All filters feature continuous cutoff and resonance control, a drive/boost circuit, and high/low pass modes. The zero-delay feedback structure ensures no zipper noise or artifacts, delivering analog clarity even at extreme settings.
