JAX SR vs Multimode Ladder Filter
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
JAX SR
This audio effect app allows selective frequency range processing for modulation effects. It offers a classic phaser with MIDI control and dynamic mix adjustment, preventing negative side effects from full-range processing. It requires a host application to function.
- Selective frequency range processing
- Classic phaser modulation
- Optional MIDI control
- Dynamic mix adjustment
- Universal app for Apple devices

The manual is here : https://audio.digitster.com/wp-content/uploads/2024/05/JAX-SR-Phaser-Manual.pdf The JAX SR Series are AudioUnits (AUv3), which allow to select a frequency range for effect processing. This one provides a classic phaser modulation effect with optional direct MIDI control assignment to the parameters. If (especially) modulation effects are applied to the entire frequency range, this usually will introduce negative side effects. The JAX [SR] Series allow a selective frequency range and dynamic adjustment of the mix easily. More information can be found on the product website at: https://audio.digitster.com/ Please note, that AudioUnits (AUv3) require a supporting host application to perform. This build (like all our latest releases) is truly 'universal', meaning, the audio unit is available for: - MacOS (Apple Silicon) - iOS (all actual iPhones) - iPadOS (all actual iPads) - visionOS (Apple Vision Pro) Requirements: MacOS 10.15++ iOS 14.0++
Multimode Ladder Filter
This app emulates a classic 1965 ladder filter, offering five distinct modes for versatile sound shaping. It provides warm analog-style distortion and the ability to drive the filter into self-oscillation for unique sonic textures. A dry/wet control allows for parallel filtering.
- 4-pole ladder filter emulation
- Five filter modes (LP, HP, BP, Notch, Resonant)
- Analog-style distortion with drive
- Self-oscillation at high resonance
- Dry/wet parallel filtering control

A 4-pole (24 dB/oct) ladder filter modeled after the topology designed by Robert Moog in 1965. Four cascaded one-pole stages with tanh saturation at input and feedback produce warm analog-style distortion that scales with drive and resonance. Five filter modes (lowpass, highpass, bandpass, notch, and resonant) cover everything from classic subtractive sweeps to sharp self-oscillating leads. Resonance drives the filter to self-oscillation at high values, generating a sine tone at the cutoff frequency. A dry/wet control enables parallel filtering.

Verdict
The clearest difference is update cadence: Multimode Ladder Filter at every 4 days against JAX SR's every 4 weeks. Multimode Ladder Filter also leads on price ($1.99 vs $6.99). JAX SR's advantage is iOS requirement (14.0 vs 17.0). On rating, ratings volume, ads and in-app purchases there is nothing between them.
