Shoom Synthesizer vs GSDSP Quantum Delay

Shoom is an expressive XY pad synthesizer. Or, more precisely, three identical synthesizers in one app. It is capable of playing any pitch in the audible range and doesn’t necessarily limit you to a particular scale. Nevertheless, if you do want to use scales, Shoom can deliver anything from common 12-tone equal tempered to xenharmonic and microtonal. Features: • Three independent synthesizers • 8–20,000 Hz pitch range • Slide freely or snap notes to scale with adjustable glide rate • Set notes to infinite hold using a dedicated toggle • Microtonal and non-octave repeating scales support • MIDI note input (including MPE), CC control and clock sync • Optional remapping of MIDI notes to the pitches of the selected scale • Bluetooth MIDI support • Inter-App Audio support with main mix and individual synth outputs • Audiobus 3 support (including AB MIDI) • Ableton Link support • 120+ bundled presets • Import and export of presets and CC maps Synthesizer engine features: • Adjustable polyphony, up to 30 voices • Two oscillators with 4 waveforms and PWM, and one noise generator • Oscillator FM cross-modulation • 4 pole (24 dB/octave) resonant low pass filter with overdrive and pitch tracking • 2 variable slope ADSR envelopes for amplitude and filter cutoff • 2 LFOs with 9 waveforms, up to 3 out of 12 simultaneously assignable parameters, trigger and global running modes, fade-in and phase controls • Y-axis position / MIDI CC#74 as modulation source with up to 3 of 15 simultaneously assignable parameters • MIDI channel pressure / polyphonic aftertouch as modulation source with up to 3 of 15 simultaneously assignable parameters • MIDI velocity modulation of amplitude and filter envelopes • Note pan randomizer • Built-in stereo delay and reverb effects

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
