Salome is a tool for recording (or importing) sounds, turning them into seamless loops, and then polyphonically play them using MPE or MIDI. CONTROL: The onscreen keypads can be latched, turning them into 2-dimensional faders for controlling various modulations. Additionally, software and hardware MPE controllers can be used (or normal MIDI, in a pinch). WORKFLOW: The entire process from sampling to playing was designed to be a fast and fluid as possible. Speed > features. UNIVERSAL: AUv3 plugins for iOS (iPhone, iPad) and MacOS (ARM, Intel) are included*. - Full Audio Unit compatibility (note that not all hosts support all AU features) - Built-in MPE keypads for multidimensional onscreen control - MPE/MIDI input and output from the Audio Unit, so you can record your performance or even control other MPE synths - 12 mode filter, based on the Oberheim Xpander design - Latch-mode lets you play the instrument using faders - Basic standalone mode included (for connectivity use the AU plugin) - Record or import sounds (WAV, AIF, MP3) and instantly play them as a polyphonic instrument - Effortless seamless loops using the non-destructive X-Fade feature Find the user manual on ruismaker.com * not all MacOS DAWs fully support Audio Unit plugins. This is not a VST plugin.

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
