Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
SinOscillators
Read full descriptionHide full description
SinOscillators is a strange synthesizer with nine oscillators. It uses a unique sine wave generation algorithm, resulting in sounds that are difficult to predict and control. Sometimes the sounds are noisy, sometimes eerie, but sometimes they're captivating enough to listen to for a long time. This app allows you to set and control the following: - Buffer: Size of audio buffer - Transition: Parameter transition time - Spread: Stereo sound spread - Volume: Overall volume - Shuffle: Randomly set oscillators to the same value - Clusterize: Set the oscillators to similar values - Harmonize: Adjust oscillators systematically - Mute: Temporarily silence oscillators - Slider: Set oscillator’s parameter lik a pitch - Button: Play or stop oscillators - Randomize: Randomly change parameters - Targets: The percentage of random parameter changes - Timer: Randomly change parameters at specified intervals
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 SinOscillators's every 3 months. Multimode Ladder Filter also leads on price ($1.99 vs $3.99). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
