Elastic Melody is a standalone iOS application and AUv3 plugin with 3 channels of synthetic sounds, an analog style step sequencer and 4 master effects. Almost all parameters can be automated and thus changed in an „elastic way“. The focus of Elastic Melody is on a fast and intuitive creation of melodies with a basic analog sound. Elastic Melody comes with a bunch of presets from well-known sound designers of the iOS scene, like "Sound of Izrael", "Red Sky Lullaby", "Nu-Trix", "JaKob Haq", "Another Machines" and others. Features: SYNTHESIZER / SEQUENCER – 3 channels, each with an analog synthesizer that is connected to an associated sequencer – Each sequencer channel has its own start/end and timing parameters for notes and automation – 14 parameters per synth engine (waveform, lowpass, highpass, env, etc.) – For each parameter, value changes can be drawn in an automation window – Solo or mute function for the 3 synth channels – Song Mode: Create easily longer sequences with setting pattern repeat and duplicating and altering a pattern MASTER FX – 4 master effects (EQ, Chorus, Delay, Reverb) – Automation for most parameters of the effects – Each FX effect has its own start/end and timing parameters for automation SONG MODE - Arrange several Pattern to a longer sequence ... a Song - Repeat count for Song Elements/Pattern - Duplicate/Rename/Delete function for Pattern and Song Elements FUNCTIONS – Undo/Redo – Various randomise functions – option to share and import presets – AUv3 support – Ableton Link support

Features
Read full description

A vintage-inspired delay supercharged with deep modulation, flexible filtering, and creative timing that pushes echoes into new dimensions. Classic Delay, Reinvented Quantum Delay takes the charm of a vintage stereo delay and fuses it with our next-level modulation system. Switch between the warm character of Tape mode and the pristine clarity of Fade mode, lock to BPM (including 5-tuplets) or dial in precise times in milliseconds. Use the Fine control for subtle push-and-pull micro-timing — or modulate your delay lines in ways traditional delays could only dream of. Sculpted Echoes Shape your repeats with switchable lowpass, highpass, and bandpass filters placed directly in the feedback path. Add modulation to create evolving tones, gentle movement, or drifting, frequency-shifting echoes. From warm analog-style rolls to shimmering, swirling textures, it’s all there. Feedback with Precision Control your delay tail behavior using either traditional % feedback or our modern dB-per-second decay system — ideal for predictable, musical decay even when the feedback path becomes complex. Enable Crossfeed for classic ping-pong stereo bounce, or push into Over-Feedback to create dense, self-building echoes that drift toward infinity. Stereo or Dual Mono Every section of Quantum Delay — delay, filter, and feedback — can switch between stereo and dual mono modes. Create tight, controlled stereo images or break them apart for wide, offset, unpredictable spaces. Dual mono modulation unlocks complex stereo interplay and beautifully asymmetric echoes. Modulation Without Limits Quantum Delay integrates our advanced modulation system, letting you modulate nearly anything: delay time, filters, feedback parameters, stereo controls, and more. Use LFOs, Random Generators, 2D modulators, Envelope Followers, Macros, and even chaotic systems to push your echoes far beyond traditional delay behavior. Or use our parameter randomisation feature to explore the plugin’s sound at random. Quantum Delay 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). More information here: https://gs-dsp.com/products
