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.
