Beatzille: little monster

Beatzille is a compact version of our monster modular synthesizer Bazille. Although its condensed feature set makes it the ‘little brother’, Beatzille is still an engaging and capable synthesizer. Power and style run in the family. Digital oscillators, analogue-style filter and flexible patching will keep you busy for a good while before thinking about tackling Bazille.

Please note: Beatzille was commissioned by German music magazine Beat for their readers. It is only available via Beat magazine, not from us or our resellers.

The current version of Avid's toolkit for building AAX plug-ins is not compatible with the Apple SDK needed to build plug-ins for Apple's new ARM/M1 processors. We are therefore not able to provide updated AAX versions on macOS, neither for Intel CPUs, nor for Apple M1. If you're a Pro Tools user on macOS, please continue using the previous version of Beatzille for the time being. Once the AAX toolkit supports Apple's M1 processor architecture, we will provide new AAX versions for macOS, with support for Big Sur and both Intel and Apple M1 CPUs.

Sights and sounds

Small and mighty

Striking the balance between too much and too little, Beatzille is the happy medium. It presents an introduction to modular synthesis and a taste of the power of Bazille without being overwhelming.


Beatzille’s oscillators embrace two digital synthesis methods developed during the 1980s: frequency modulation (FM) and phase distortion (PD). We also added a process we call fractal resonance (Fractalize), which sounds similar to the classic oscillator sync effect when swept.

All three synthesis methods run simultaneously, so you can combine them to create an extensive range of sounds. Beatzille is great at generating weird modular blips and squeaks, but you can even coax soft pads and organic keys from the oscillators—as demonstrated by the factory library. Add modulation for even more sound possibilities.

The filter is a favourite in the sound designer’s toolkit. Cut frequencies, boost others, add texture and colour. Beatzille’s analogue-style filter complements the digital oscillators, providing warmth and drive. And its self-oscillation capability opens up some intriguing sound design opportunities.

Even with a single filter Beatzille offers plenty of creative horizons. The six parallel outputs (highpass, bandpass and four types of lowpass) with multiple modulation options make it easy to create complex, shifting textures.

Beatzille has only one built-in effect, but it’s good one: stereo delay with optional host sync. Push your sound around in space with independent delay times and volumes for each channel. Conjure ghostly echoes using tape-like wobble and filtering or set up endless repetitions. Tweak all controls to find the perfect delay.
