EG Nodes is a clip based Audio Unit host with sequencing capabilities to play external instruments, Audio Unit or MIDI hardware and create a complete audio project. A powerful and flexible groovebox to perform or create musical projects from scratch in a fast and easy way. BUILTIN MIDI GENERATOR Use the builtin nodes to play instruments, apply effects and perform. NOTE/CHORD - generates a single note or a chord ARPEGGIO - generates chord arpeggios SEQUENCER - to play a note sequence RHYTHM - to play drums, percussion or rhythmic instruments PIANO ROLL - to write more complex MIDI part in a classic piano roll editorFEATURES GENERATIVE - to continuously generate sequences evolving in time MIDI FX - to host external MIDI FX Audio unit like sequencers, piano rolls and others MIC/INPUT NODE a simple node input audio from your device mic or an external usb interfaces. You can play your guitar or any instrument together with your song and record it using the Audio/Sampler node. BUILTIN AUDIO/RECORDER/SAMPLER Use the Audio Sampler node to import audio files (wav, mp3, mov, mp4, caf or aiff). Audio node is capable of sync the loop to your project tempo using pitch shifting algorithm to stretch the audio without changing its pitch. You can create your own instrument, adding a sample and playing it via the MIDI sequencer nodes. You can also use the Audio node to record the output from any node in your project or from a mic/line (using the MIC node). SONG NODE to link scenes and create a song structure. You can add how many song nodes you like and assign each one to a different section. MIX GROUP NODE to create mixing busses and group nodes.

  • Switchable stereo/dual mono modes
  • Advanced modulation sources (LFO, Random, Envelope)
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
