M2DX vs LP Audiobook

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. KEY FEATURES - Built-in on-screen keyboard with velocity and octave control — play standalone, no hardware needed - 6-operator, 32-algorithm DX7-style FM synthesis - M2DX's own original FM presets, plus DX7-format .syx bank import (bring your own) - A 6-stage FX chain: EQ, Drive, Chorus, Reverb, Stereo, Maximizer - Low-latency audio with AVAudioSourceNode direct rendering - AUv3 plug-in — use M2DX as an Audio Unit (AUv3) in compatible hosts OPTIONAL MIDI (not required to use the app) - Connect any MIDI controller over Bluetooth or USB if you have one - Native MIDI 2.0 — UMP with 16-bit velocity and 32-bit controllers - MIDI-CI Property Exchange — patch names appear on compatible controllers (for example, KORG KeyStage) - MIDI Learn for hands-on control MIDI 2.0 done natively, classic FM done faithfully. The FM engine is built on Dexed / msfa (Apache License 2.0). M2DX is an independent product and is not affiliated with, endorsed by, or sponsored by Yamaha Corporation.
