Tuner-Flow — Chromatic Tuner A fast, accurate chromatic tuner for guitar, bass, ukulele, banjo, and more. Tune by ear or by eye with two meter styles — a classic strobe display and a traditional needle meter. The string guide shows all your strings at a glance, highlights the closest match as you play, and locks in with a satisfying haptic when you're spot on. Enable auto-advance and it moves to the next string automatically, so you can keep both hands on the instrument. Switch to chromatic mode for instrument-agnostic tuning — ideal for vocals, wind instruments, or anything that isn't a guitar. Features Strobe and needle meter modes Auto string detection with manual override Auto-advance through strings when in tune Chromatic mode for any instrument or voice 17 tunings across guitar, bass, ukulele, and banjo Reference tone playback per string Adjustable A4 reference pitch (420–460 Hz) Microphone sensitivity and input source controls Haptic feedback when locked in tune

Make any sound move. RasterFX is a playable modular multi-effects processor for iPhone and iPad. Use it standalone with a microphone, an imported audio file or built-in signals — or load it as an AUv3 audio effect in AUM, GarageBand, Logic Pro for iPad, Loopy Pro, Cubasis and other Audio Unit hosts. BUILD YOUR EFFECT CHAIN Choose from Filter, Delay, Drive, Reverb, Grain, Repeat, Motion and Dynamics. Arrange up to six plates in series or split them into parallel A/B paths. Reorder the chain and the sound changes with it. MODULATE ANY CONTROL Patch LFOs, envelope followers, random and chaos sources, step sequencers, MIDI, macros, the XY pad or device tilt to any control. Create up to 16 modulation lines, with live arcs showing exactly how the sound is moving. PERFORM THE PATCH Morph between four snapshots on the XY pad. Turn eight macros. Hold four momentary throws for stutter, sweep, reverse and freeze. RasterFX is built to be played with one hand, not programmed and left alone. GENERATE, LOCK, EVOLVE Nudge a patch, reshape it or roll a new one. Lock the parts you want to keep, undo any result and save the seeds worth returning to. Evolve lets the patch drift over time while staying anchored to the sound you chose. SEE WHAT YOU HEAR Every effect has its own live visualizer. The CRT and halftone interface makes filters, delay taps, grains, dynamics and modulation visible without turning the screen into a wall of meters. RECORD THE RESULT Record the processed output to WAV, rename takes and share them from the app. FREE TO START. PRO ONCE. Free includes all eight effects, all modulation sources, every factory preset, three plates, four modulation lines and 60-second recordings. No ads, account, watermark or reduced audio quality. RasterFX Pro is a one-time purchase — not a subscription. It unlocks six plates, 16 modulation lines, split routing, XY snapshot morphing, Evolve, A/B compare, unlimited recording length and your own saved presets. Your saved sound always plays back exactly as created, even if it uses Pro features; Free limits editing, never playback. Made for headphones, late at night.
