midiLFOs is a MIDI controller app and AUv3 MIDI effect that sends MIDI modulation control data to other music apps and external synthesizers. It has four independent LFOs that send 7 bit MIDI CC messages in repeating Low Frequency Oscillating patterns. The LFOs can be the various standard shapes (sine, saw, triangle, square, sample and hold) but can also modulate each others amplitude and rate to create even more interesting shapes. midiLFOs does not make music or sound by itself, it controls other MIDI capable synth apps and devices in your studio. You can use it to modulate the filter cutoff frequency of your favorite synth app, the pan position of the hi hats in a drum machine app, the feedback amount of a delay effect, or the pitch of an external hardware synthesizer. Or you can do all four at the same time. midiLFOs features: - Four independent LFOs that send 7-bit MIDI CCs - Easily configure CoreMIDI port, channel, CC# per LFO - Use in other apps as a MIDI Audio Unit Effect - Easily adjust shape, rate, offset, lag per LFO - Modulate the rate and amount of an LFO using other LFOs - Sync LFOs to MIDI clock or Ableton Link - Map trigger, LFO rate, and modulation amount values to incoming MIDI Designed to be easy to configure and use, midiLFOs gives you a quick to configure and easy to use MIDI LFO controller toy with extra features that also make it a useful pro music studio tool. AUv3 support requires an AU host app that supports MIDI effects, such as AudioBus 3, AUM, etc.
GSDSP Quantum Distortion
Explore four distinct distortion effects—Saturation, BitCrush, Ring Modulation, and Downsampling—blended and controlled via an intuitive XY pad. Shape harmonics, reduce digital resolution, introduce inharmonic motion, and create classic digital degradation for unique audio textures.
- Four distortion algorithms (Saturation, BitCrush, Ring Modulation, Downsampling)
- Intuitive XY pad for blending effects
- Custom waveshaping saturation
- BitWarp for tonal variation
- Tunable oscillator for ring modulation
- Adjustable downsampling rate and jitter
- AUv3 audio effect plugin

Four complementary distortion algorithms — Saturation, BitCrush, Ring Modulation, and Downsampling — blended and shaped through an intuitive XY pad. Saturation Shape harmonics using Quantum Distortion’s custom waveshaping saturation. Adjust Drive to set the intensity from subtle warmth to strong coloration, and use Asymmetry to introduce controlled even-harmonic emphasis of vintage tube characteristics. BitCrush Reduce digital resolution using BitCrush and reshape the crushed signal with BitWarp, which bends the quantization curve for additional tonal variation. This combination allows precise control over both the amount of reduction and the character of the resulting digital artifacts. Ring Modulation Introduce inharmonic motion using ring modulation, generated by multiplying the input with a tunable oscillator. Adjust frequency and amount in real time to create anything from light metallic shading to dense, shifting sidebands. Downsampling Lower the sample rate using Downsampling, reducing temporal resolution for classic digital degradation effects. Set the rate down to 200 Hz or introduce Jitter for controlled randomness, adding instability and movement to the downsampled signal. XY Pad Blending Navigate between the four distortion algorithms using the XY pad, allowing smooth transitions or static blends across the processing modes. The background updates to reflect the current region, providing clear visual feedback while exploring hybrid distortion shapes and interactions. Quantum Distortion is an AUv3 audio effect plugin compatible with Logic Pro, AUM, Cubasis, GarageBand and many more. A Desktop version is also available for Windows and macOS (VST3 / AU / AAX).
