REF-440: The tuner that disappears when you need to play. REF-440 is designed for musicians who demand precision and clarity. Inspired by Dieter Rams and Teenage Engineering, every pixel serves a purpose. No ads. No clutter. Just a precision instrument that helps you tune and get back to making music. Precision You Can Feel REF-440 uses the McLeod Pitch Method (MPM) algorithm, optimized for real-time guitar tuning. With ยฑ2ยข accuracy, adaptive smoothing, and intelligent note locking, you get stable readings that don't jump around โ€” even in noisy environments. Designed Like an Instrument The interface mimics a hardware tuner: a dark "faceplate" display panel, needle meter with ghost trails, and LED indicator. The 135-point note display is readable from across the room. Orange means action, neutral means success. Context-Aware Instructions Forget "flat" and "sharp." REF-440 tells you what to do: TIGHTEN or LOOSEN for strings, TUNE UP or TUNE DOWN for chromatic mode. Physical actions for physical instruments. Every Guitar Player's Needs Guitar โ€” 12 tuning presets including Standard, Drop D/C/B, Open G/D, DADGAD, and more Bass โ€” Standard, Drop D, Half-Step Down, 5-String Ukulele โ€” Standard (High-G), Low-G, Baritone Chromatic โ€” Detect any pitch across the full frequency spectrum Thoughtful Customization Reference pitch from 415 Hz (Baroque) to 466 Hz (bright orchestral) Capo support (0-12 frets) Sharp/flat display preference (A# vs Bb) Adjustable noise gate for any environment Optional in-tune chime (customizable sound) Keep screen on while tuning Premium Details Standby mode saves battery โ€” tap to resume Home screen and Control Center widgets (iOS 18+) Siri Shortcuts for reference tones Live Activity during tuning sessions VoiceOver accessible with meaningful labels Respects Dynamic Type and Reduce Motion settings Built for Musicians, by Musicians REF-440 is a single-purpose tool that does one thing exceptionally well. No subscriptions, no premium upgrades, no feature gates. Just a tuner that works.

An electric guitar effect for the laid-back sound: squashed until nothing jumps out. Just past clean. Wobbling a little. One repeat behind. That sound is not one pedal โ€” it is a whole vintage clean chain, and jj-midnight is all of it in a single AUv3 insert. Four blocks in signal order, each with its own on/off switch, plus a master strip. COMP โ€” An optical compressor with program-dependent release, the way a real opto box behaves: one knob for threshold, ratio and make-up together, so it squashes without asking you to think about it. A gain-reduction meter reads out what it is doing. This is the block the whole plug-in is built around. DRIVE โ€” Asymmetric soft clipping voiced for second harmonic rather than fizz, a tone rolloff, and a 1x12 cabinet with a movable mic position. Low gain on purpose. It goes from clean with weight to the edge of breakup and stops there. WOBBLE โ€” Amp-style amplitude tremolo with an LFO that morphs from a sine sway to a hard chop, free-running or synced to your host's tempo. SPACE โ€” One slapback repeat with no feedback, into a spring tank with dispersion allpasses for the chirp a real tank makes. THIRTEEN FACTORY PRESETS Default, Laid Back, Escondido, Porch Light, Whisper Trem, Magnolia, Breeze, Midnight, Sensitive Kind, Faded, Cassette, Night Drive, Flat & Even. Save your own from the preset window; swipe left to rename or delete. WORKS WHERE YOU WORK An Audio Unit v3 effect: GarageBand, Logic for iPad, AUM, Cubasis, BeatMaker, and any other AUv3 host. The included app is a working player, so you can hear the plug-in on a real guitar part before you open a DAW at all โ€” two dry recordings are bundled, or run your own playing in through the microphone. The panel is drawn procedurally rather than assembled from bitmaps, so it stays sharp at whatever size your host gives it, on a phone or a 13-inch iPad. FREE TO TRY Seven days free from first launch. No account, no signup, no subscription. After that, one purchase unlocks it permanently on all your devices. If you do not buy it, the editor keeps working and audio passes through dry โ€” nothing you built disappears. jj-midnight is an original effect. Preset names point at a feel or a place. It is not affiliated with, endorsed by, or associated with any artist, label, or other plug-in maker, and does not recreate any particular recording.
