Q Sahara
Read full descriptionHide full description
Drive it. Shape it. Move on. Q Sahara is an input-driven compressor designed for quick decisions and musical results. There is no threshold to chase and no millisecond math to interpret: drive the signal into Sahara, set the ratio, and let its program-dependent behavior follow the music. INPUT-DRIVEN COMPRESSION A fixed internal threshold means compression is controlled by how hard you drive the input — just like classic analog workflows. MUSICAL TIMING Attack and release are program-dependent, adapting to phrasing, groove and dynamics instead of fixed time values. RATIO WITH CHARACTER Ratio and knee work together. Lower ratios stay smooth and forgiving; higher ratios add firmness and control without limiter behavior. MADE FOR iOS • AUv3 plugin — use it in AUM, GarageBand, Logic Pro for iPad, Cubasis, Loopy Pro and other AUv3 hosts • External sidechain support with dedicated sidechain high-pass filter • Standalone app included • Two hand-crafted themes: Sand Dune and Black Sand • HD and Eco oversampling modes • Zero samples latency, ultra-low CPU • A/B compare and preset management • Factory presets, including artist presets by Grammy-winning engineers FOCUSED BY DESIGN No unnecessary controls, no distractions. Sahara does one thing and does it well: it delivers instant results, stays responsive to your material, and lets you mix by ear instead of by numbers. “Really interesting compressor! Sahara seems to improve the sound of everything I put it on.” — Mark Linett, three-time Grammy-winning producer and engineer “I reach for the Sahara compressor when I want character. It shines on bass, acoustic guitar, snare, parallel drums, and more!” — Brian Vibberts, seven-time Grammy Award-winning producer and engineer

Seyfert is a delay unlike your others: every echo spawns at its own place in an orbit around you, and the whole constellation slowly revolves. Turn up Feedback and you don't just add repeats, you spawn more echoes into the orbit, from a single tight slap to a dense, spiralling cloud. Spin revolves the whole field around you. Doppler bends the echoes in pitch as they whirl toward and away. 3D wraps them around your head on headphones. Lift the repeats an octave into crystalline shimmer, drop them a sub-octave for weight, or detune them into a chorus. A lush reverb blooms around the echoes, never the dry signal, so your source stays clear while the repeats dissolve into space. Features: - Orbital echoes, where Feedback sets how many circle you - Spin, from a gentle drift to a full whirl - Doppler pitch-bend as the orbit turns - 3D binaural imaging for headphones - Shimmer and transpose, up or down one octave (octaves, fifths, sub-octaves) - Per-echo Trail tone, tape Wobble, and Drive - Lush reverb applied to the echoes - Full 5-band EQ on the wet signal - Orbit and Ping-Pong patterns, tempo sync - 18 factory presets, plus save your own - Standalone app and Audio Unit (AUv3) for GarageBand, AUM, Logic, and more No accounts, no tracking, no data collected. Everything stays on your device.
