Simple, but deadly. Hyper Boost combines a two-band tone control with a hard-hitting soft clipper. Use it early in the chain as a bold saturation effect or throw it on late for subtle, precision mix adjustments. A power-up for your sound. Tone Control - Retro-inspired treble and bass tilt filters. Gentle, not surgical - Adjustable center frequency - Three configurations: Pre (EQ before clipper), Post (EQ after clipper), Emphasis (saturate a frequency band while keeping flat response overall) - Output trim Clipper - Drive input up to +36 dB - Adjustable ceiling and edge for precise control over the clipping curve - Three clipping algorithms: - Juicy: reproduces an infamous stock clipper - Tight: adapted from a classic soft-knee limiter - Hardest: loud and brash hardware-style clipping - Real-time curve visualizer with max peak metering Core Features - Morph Settings for smooth transitions between two complete configurations - Auto Bypass saves CPU when input is silent - AB settings comparison - HQ mode with 4x oversampling and ADAA - One-click loudness matching - All parameters automatable with precise playback - Light and dark interface modes - Internal undo/redo - Auto gain - Use your AUv3 plug-in in a compatible host app or DAW - Standalone app includes support, manual links and in-app purchase options for license purchase Two-week trial included, one-time purchase for full unlock. Unlock your plug-in via in-app purchase from the standalone app or activate in the plug-in using an existing desktop license. Your in-app purchase activates the plug-in on all of your iOS devices. Owners can claim a crossgrade code in the standalone app to receive a discount on a desktop license.

Melthaven is a note-triggered phase shifter built to give guitarists and bassists organic, rhythmic movement that syncs to their playing, rather than a fixed LFO. It's also highly suited for a number of synth basses and sounds with sharp attacks and fast decays. Its analog-modeled OTA filters provide deep resonance and character, ranging from wah-like effects to complex, shifting formant textures or even experimental tones, like bubbling or hard, slappy effects. For bright, harmonically dense signals – such as saturated or overdriven tones and synthetic sounds – the effect range also includes growls and glistening sweeps. FOCUSED ON BASS & GUITARS The effect was specially developed to respond to the frequency response and transient peaks of electric guitars and basses. Every pluck, pop, or pick attack re-triggers the phase sweep, effectively turning your rhythmic timing into the "engine" of the effect. USING LOOPS? BREAK THEM OPEN Add various resonant effects like growls, or vintage bark / quacks "after the fact." This unlocks a level of control usually lost the moment a loop is bounced. Instead of being stuck with locked-in sound design, you can now reshape the envelope of any pre-recorded sample, breathing new life into your loop library. FOR SYNTHS & SOUND DESIGN: INPUT DEPENDENT Soft signals like pads or heavy/layered effects can produce wild, unpredictable responses. While such use is outside the plugin's core design, the smoothing feature can tame these re-triggers, yielding a flow that can feel organic and physical in its instability when operating beyond the plugin’s transient-focused comfort zone. MOVING BEYOND ENVELOPE FILTERS The plugin uses low-latency note detection paired with its own envelope generator and LFO, allowing sculpting and even reshaping each note’s modulation profile or filter envelope. It even detects notes that hide under a consistent signal amplitude when using a traditional envelope follower. BASE FEATURES: - Built around a versatile preset from the Pro version to suit a wide variety of applications - Controls: feedback & panoramic position, attack & hold timings, LFO Rate - Smoothing: from envelope shaping to creating a weighted, fluid response, giving note sequences a sense of physical momentum - Low-latency engine: preserves natural playing feel when used as a real-time effect PRO FEATURES - Requires Pro Edition Upgrade (In‑App Purchase): - Additional envelope parameters, several envelope flavors with pre-mapped control subsets - Pro presets encompassing both strong and milder effects, including the quintessential rubber bass - Enhanced stereo phaser modes & internal stereo re-imaging modulator (for formant-like effects and more) - Vintage-style phaser feedback that can optionally build or ramp with each note onset (non-rampable in the base version) - Instant visual feedback via an audio scope with dual-channel envelopes overlaid on the input waveform TECHNICAL NOTES: - Place before creative effects (unless experimenting). It can be used before or after harmonic processing (saturation, amp sims) depending on your preference - Response may vary on sustained notes with shifting harmonic content - Not optimized for upright bass due to its reliance on sharp signal transients - Note detection involves statistical signal processing and confidence intervals. Weak transients and phantom notes could lead to a loss of output determinism, i.e. sensitivity to changes in certain project settings - While it offers multiple layers of real-time control, Melthaven operates primarily as an automatic effect; for full manual filter manipulation, please refer to RealPhase, a separate app PLEASE NOTE: • The Pro Edition Upgrade is offered as a one‑time In‑App Purchase • An AUv3-compatible host is required to use this app • Suported sampling rates: 44.1, 48, 96 kHz
