Mighty Synth Sampler turns any sound into a playable instrument. It's a free, fully-featured synth and sampler for iPhone, iPad, and Mac built for musicians who want to create, layer, and perform with their own sounds and SoundFonts (SF2/SFZ). ROMPLERS RULE! The app is built around four pillars: • The Synth A full subtractive synth engine powered by AudioKit. Three independent oscillator layers with volume, semitone, detune, and pan controls. Shape your sound with amplitude and filter envelopes, a low-pass filter, LFO, unison, glide, drive, and more. A built-in arpeggiator, flexible play surfaces, and MIDI support round out a synth that's deep without being overwhelming. • The Sampler Build your own sample-based instruments from scratch. Record directly in the app or import audio files, map them across the keys, set loop points, adjust root notes and note ranges, and save your creations as reusable instruments and banks. • Sound Packs The app comes with a built-in starter bank and supports downloadable sound packs both free and paid. New packs are added to the store without requiring an app update. You can also create your own banks and share them with others. • AUv3 Support Four AUv3 plugins in one app: Mighty Synth (instrument), Mighty Sampler (audio effect for capturing and building instruments), Mighty Effects (standalone effects chain), and Mighty MIDI (MIDI processor and play interface). Load them individually in your favorite DAW or AUv3 host. Features • Free app with all core features included • Three-oscillator synth engine with detune, pan, and semitone control per layer • Amplitude and filter envelopes with per-oscillator scope • Low-pass filter with cutoff, resonance, and key tracking • LFO targeting filter cutoff, pitch, or volume • Unison with up to 8 voices, width, detune, and offset control • Effects: reverb, delay, chorus, drive, phaser, compressor, panner, and more • Built-in arpeggiator with BPM sync, octave range, and pattern modes • Multiple play surfaces: keys, pads, All 4ths layout, scale layout, and more • 16-slot sampler with loop points, root note mapping, and note range editing • Record audio directly in-app • Import audio files and SF2/SFZ SoundFonts • Downloadable sound packs (free and paid) • Create, export, and share your own instrument banks • Four AUv3 plugins: Mighty Synth, Mighty Sampler, Mighty Effects, Mighty MIDI • MIDI CC mapping • Available for iPhone, iPad, and Mac Thank You & Enjoy!

Did you know your iPhone & iPad has multiple microphones with polarity patterns that are all available under the hood? This app accesses all of them. Select a mic and a polar pattern (mono only) or choose stereo recording in Settings. Monitoring starts at app launch, hit Record, add a marker if you hear something cool. Then play your recordings back, share them, and use them in your creations. Input gain is adjustable and you can push it to distort if you'd like. If you plug in wired headphones you can listen to your environment and what you're recording, there's plenty of extra monitoring gain there too if you need it. Bluetooth monitoring is also available with latency, but with noise cancelling enabled it works pretty well. All your recordings are stored on device and accessible in the Recordings page, where you can see any cue markers you've made, scrub through long recordings, rename the file, and share the file outside the app.
