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.
