About

GSDSP MagicDelay

This app offers a unique spectral delay effect with advanced control over thousands of parallel delays using a single curve. It allows for real-time modulation, tempo-syncing, and precise feedback management for expansive sonic exploration.

Highlights
  • Spectral delay with single curve control
  • Tempo-synced grids and free-flowing motion
  • Real-time curve modulation and morphing
  • dB/s feedback decay system
  • Built-in highpass and lowpass filters
  • Crossfeed for stereo image expansion
  • Feedback Over for values beyond 100%

Do we need yet another Delay? Of course! We need thousands of delays working in parallel with full spectral control. One Curve. Infinite Delays. MagicDelay lets you control thousands of spectral delays with a single, elegant curve. Apply BPM-type grids to lock your shapes perfectly to the tempo, or let them flow freely for more experimental motion. With the powerful Curve Modifier, you can modulate, morph, and reshape your delay patterns in real time — turning one curve into endless rhythmic and spectral variations. Thoughtful Feedback control Control your delay tails using either traditional feedback in percent or our unique dB-per-second decay system — created specifically to manage the feedback of many varying delay times at once. Using dB/s ensures predictable, consistent tail lengths across the entire spectrum, even in the most complex settings. Sculpt the Spectrum Refine your delays with built-in highpass and lowpass filters, adding warmth, clarity, or sparkle exactly where needed. Activate Crossfeed to expand your stereo image and create immersive, wide-angle motion. And when things get wild, use Kill to instantly mute and clear the delay line — total control at any moment. Beyond 100% Need more? Push into new sonic territory with Feedback Over, allowing feedback values beyond the traditional 100% limit. From endless atmospheric swells to self-oscillating spectral chaos, MagicDelay gives you room to explore — and break — the rules. A New Dimension of Delay Whether you’re a musician, sound designer, or producer, MagicDelay is a spectral playground built for discovery. Its multi-curve design, deep modulation system, and flexible feedback architecture make it a truly expressive tool for shaping delays far beyond the ordinary. MagicDelay 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).

About

SinOscillators

Features
Read 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
