LogSynth vs RocketVerb

LogSynth is a polyphonic virtual-analog synthesizer built for people who care what's actually happening in the signal path, not just what the preset browser looks like. Every voice runs five anti-aliased oscillators (sine, triangle, saw, pulse with PWM, and a band-limited impulse train) plus a dedicated sub-oscillator and noise source, mixed per-voice with independent amp envelopes. Chunky oscillators, crisp effects and a zero-delay-feedback state-variable filter — switchable low/high/bandpass. The drive effect is powered by a physically modeled diode circuit, numerically integrated rather than a lookup-table approximation, so pushing it into saturation behaves the way an actual analog drive would. FEATURES - 8-voice polyphony, 5 oscillators + sub + noise per voice - Zero-delay-feedback state-variable filter with resonant feedback and diode drive saturation - 5 independent oscillator envelopes plus a dedicated filter envelope - 2 assignable LFOs and an 8-slot modulation matrix - Built-in chorus, delay, FDN reverb, and 4-mode distortion - 41 factory presets across Bass, Lead, Pluck, and Effects - One-tap patch randomizer with adjustable intensity - Real-time oscilloscope, on-screen keyboard, and CoreMIDI input - Runs standalone or as an AUv3 instrument inside AU hosts Whether you're sound designing from scratch or dropping it into a DAW as a plugin, Logsynth gives you the same engine everywhere — no watered-down mobile version, no feature gating between standalone and plugin modes.

RocketVerb is a creative algorithmic reverb for iPhone and iPad, designed to transform instruments, vocals and recordings into spaces that move, bloom and evolve. Its character was shaped through the study of public space audio, planetary recordings and astronomical data sonifications. Their spectral movement, density and texture were translated into 38 internal profiles. RocketVerb does not replay those recordings as samples or fixed impulse responses. Every reverb tail is synthesized in real time. SHAPE YOUR SPACE Use five focused controls to build the foundation of the reverb: - Pre separates the original sound from the reverb bloom. - Density moves from open reflections to smooth clouds. - Length controls the duration of the tail. - Size changes the perceived scale of the environment. - Shape moves between tight, blooming and suspended responses. MOVE THROUGH THE GALAXY The interactive Galaxy cursor modifies distance, brightness, motion, scatter and the balance between early reflections and the tail with a single two-dimensional gesture. SIX CREATIVE EFFECTS - Radiation adds energy, mass and charged texture. - Orbit introduces stereo movement and subtle pitch drift. - Filter shapes the tonal range of the processed signal. - Granular Cloud transforms audio into layered, evolving slices. - Comet Trails creates rhythmic and atmospheric delay repetitions. - Dust introduces organic noise, texture and movement. Granular Cloud and Comet Trails include interactive 8-step patterns and can process either the direct input or the reverb signal. INFINITE FREEZE Capture the current atmosphere and keep it circulating indefinitely. Release Freeze to return smoothly to the live reverb tail. 144 FACTORY PRESETS Explore eight categories covering practical mix spaces, cinematic environments, orbital motion, granular textures, dusty planetary colors and deep ambient tails. Save your own presets directly from the app. AUv3 AND STANDALONE Use RocketVerb as an AUv3 effect in compatible hosts such as GarageBand, Logic Pro for iPad, AUM and Cubasis, or run it as a standalone app with a microphone or connected audio interface. SOURCE DISCLOSURE Some public NASA audio and sonification material was used as source material during development. This factual disclosure does not imply NASA review, approval, sponsorship, endorsement or affiliation. RocketVerb is an independent ZAK Sound product. The original recordings are not replayed by the app.
