M2DX vs Reel2

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.

Reel2 is a characterful AUv3 tape delay for iPhone and iPad. Add warm, musical echoes inside compatible Audio Unit hosts, then shape the repeats with tape-inspired controls for saturation, tone, age, wow and flutter, feedback, width, and dry/wet mix. Use free-time mode for manual delay times, tap tempo when you want to play the delay in by feel, or host sync when your session tempo should drive the repeats. Factory presets make it quick to start, and user presets let you save your own favorite echo settings. Reel2 includes a five-minute trial for audio processing. The Full Version unlock is a one-time non-consumable in-app purchase. Features: - AUv3 effect for compatible hosts - Free-time, tap-tempo, and host-tempo modes - Natural feedback through saturated self-oscillation - Tape age, tone, saturation, wow and flutter - Stereo width and equal-power dry/wet mix - Factory presets and saveable user presets - One-time Full Version unlock with restore support
