Harmonizer

Read full description

Harmonizer - AUv3 is a real-time vocal harmonizer for iPhone and iPad. Sing into a microphone, select piano keys or chord pads, and hear live harmonies with low latency. Use it as a standalone instrument or load it as an AUv3 effect in compatible hosts such as GarageBand and Logic Pro for iPad. Key Features: - Live Vocal Harmonies: Process your voice in real time with harmonies based on held notes, piano keys, chord pads, or connected MIDI input. - Standalone and AUv3: Use Harmonizer as a standalone app or as an AUv3 audio effect in compatible music apps. Record the harmonized result directly in your host project. - Chord Pads: Play and hold chords with touch pads. Move between pads naturally, prepare the next chord while another is held, and use multiple octave ranges within each pad. - Audio Controls: Adjust dry vocal level, harmony level, output gain, and, in the standalone app, reverb amount and space preset. - Custom Chord Sets: Create, rename, duplicate, edit, and delete chord sets for different songs or performances. Choose the number of pads, chord roots, qualities, octaves, and pad layouts. - Piano Keyboard: Play with a multitouch piano keyboard designed for live performance. Choose Glide mode for sliding notes or Scroll mode to move across the keyboard while continuing to play. - iPad Dual Keyboard: On iPad, use two independent keyboard rows with separate positions for wider playing ranges. - MIDI Input: Use connected MIDI keyboards and controllers to play harmonies. MIDI works with chord pads and keys, including AUv3 host MIDI where supported. - MIDI Mapping: Map MIDI notes to chord pad positions and map MIDI knobs to key mixing controls such as Dry, Harmony, Reverb, and Output level. - Hand Control: Optionally control chord pads using the front camera. Hover over a pad with your hand and pinch to hold its chord. Includes a short tutorial plus low-light, no-hand, and multiple-hand guidance. - Local Processing: Microphone audio, camera input, chord sets, and performance settings stay on your device. Harmonizer does not upload or sell your audio or camera data. Enjoy!

Give your sound a new direction. Sampledex Effect Shift brings 50 effect choices, seven hands-on macro controls and the seven-band Bender EQ to iPhone and iPad. Add drive to a drum loop, movement to a synth or space around a melody, then shape the result to fit your track. FIND A STARTING POINT Choose from 51 factory presets: Default plus a starting sound for each of the 50 effects. A factory preset recalls a complete sound. Use the separate effect menu when you want to change the algorithm while keeping your other settings. CHOOSE YOUR CHARACTER Explore drive, digital textures, filters, chorus, flanging, phasing, tremolo, ring modulation, delay and reverb. Start with an effect, then turn Amount, Tone, Time, Mix, Dimension, Sparkle and Output to make it your own. SHAPE IT WITH BENDER EQ Follow seven colored band curves and their numbered handles. Select a band to adjust frequency, gain and Q directly. Use Fine for smaller graph movements, or lock dragging to frequency or gain. High-pass, low-pass and Prism controls give you more ways to shape the response. COMPARE AND KEEP YOUR IDEAS Use EQ A/B to compare two settings and copy a favorite into the other slot. Save the full sound as a preset and import or export preset documents when moving between your workflows. Each instance keeps its own sound in your host's project state. BUILT FOR TOUCH Move between Effects, Bender EQ and Advanced pages. Scroll to reach every control, enter a precise value or turn a textured macro knob. Switch Light or Dark directly from the touch header, or use the theme menu in Advanced. Your theme and settings return when the instance is restored. BRING IT INTO YOUR MUSIC WORKFLOW The included AUv3 audio effect extension loads in compatible hosts. The containing app also offers live input processing: connect headphones or an audio interface, then enable live input. Microphone permission is requested when you enable input. Your host manages audio when you use the extension. GO FURTHER Explore HoloRune character, spatial modes, EQ routing, parallel mix and Mid/Side levels in Advanced. Sidechain ducking requires a compatible host and a routed sidechain source.
