About the App

Curious about how to build your own sounds, tweak classic synth tones, or maybe just mess around with arpeggios and effects? FM Synthesizer [SynprezFM II] by Jean-Marc Desprez packs all that fun and freedom into one easy-to-use package.

App Features

• Dynamic Multitouch Keyboard
  Play and experiment with melodies using a keyboard that responds to your touch. Slide your fingers for after-touch vibrato, or shift up and down octaves whenever inspiration strikes.

• Polyphonic Synthesis
  Create rich, layered sounds with polyphony that scales up to 16 channels—even on modest devices. That means more notes and complex chords, just a tap away.

• Built-in Arpeggiator and Effects
  Spice things up with the integrated arpeggiator and a bunch of effects that can add depth and space, especially when listening with headphones.

• 1024 Instrument Patches
  Explore a massive library of instruments—classic leads, smooth pads, digital bells—plus, you can modify these or make an entirely new patch from scratch.

• Yamaha DX7 Emulation & Sysex Support
  Want to recreate those iconic vintage tones? FM Synthesizer [SynprezFM II] brings true DX7 emulation. Load sysex files into your setup and play them right away.

• Custom Patch Creation
  Tweak existing sounds or cook up brand-new patches starting with an ‘init voice.’ Save your creations directly in the app, with advanced editing tools available in expert mode.

• WAV Recording
  Record your sessions straight to WAV files so you won’t lose that spontaneous idea.

• MIDI Keyboard & Bluetooth Support
  Plug in your MIDI keyboard via USB, or skip the cables and use Bluetooth. Multiple MIDI keyboards? No problem—connecting more than one is a breeze.

  Lay down simple grooves or rhythmic patterns using the built-in step sequencer.

• Expert Mode & Micro-tuning

  Works smoothly on smaller screens, and you can even run two synth engines at once, thanks to an optimized design.

• More Under the Hood
  Enjoy subtle tweaks and improvements—like a pseudo compressor for bigger sound, improved MIDI support, better storage integration for all devices (including Android 11+), and handy VU-meter peak indicators.
