M2DX vs PocketTone

M2DX is a 6-operator, 32-algorithm FM synthesizer for iPhone, built from the ground up in pure Swift 6. Open it and play immediately — tap the built-in on-screen keyboard and start making sound with M2DX's own hand-crafted presets. No external hardware or MIDI controller is required. The FM engine is a bit-exact port of the open-source Dexed / msfa DSP, verified sample-for-sample against the reference. It is also compatible with the classic DX7 patch format: bring your own DX7-format .syx banks and play them alongside M2DX's originals.

PocketTone is a hand-drawn, retro pocket synthesizer you can play anywhere. Tap the keys and a tiny lo-fi synth comes to life — complete with a green LCD, slide switches and chunky buttons, all lovingly hand-drawn. WHAT YOU CAN DO • Play five retro voices — Piano, Flute, Violin, Fantasy and Guitar. • Program your own voice the way the original did it — an eight-digit code typed on the calculator keys: waveform, envelope, vibrato, tremolo. • Jam over ten built-in rhythms — March, Rock, Bossa, Samba and more. • Shape the sound with octave, volume and a melody/rhythm balance. • Add tape-style Delay and lo-fi Crush effects. • Record what you play and share the audio with anyone. • Use the melody memory — Auto-Play, One-Key play and a built-in demo tune. • Flip to calculator mode… then play the keypad as a melody. The classic pocket-toy party trick, faithfully recreated. POCKETTONE PRO A single one-time purchase unlocks everything: all voices, all rhythms, recording & sharing, the melody memory, and the effects. No subscription — yours forever. Made as a love letter to the pocket musical toys of the 80s.
