Electronic Piano Synthesizer XS is the worlds first piano synthesizer for the iPhone. Like the iPad version, EPS XS is based on a 32-bit realtime sound engine the sounds are computed on the fly and no samples are used.
The EPS XS gives you possibilities you don´t have with any other Piano, EPiano or Synthesizer on the iPhone. You can adjust the sound while you play on the keyboard and hear the changes immediately. That is what you need to tweak your own sounds. The EPS XS is not only for EPiano sounds, you can also make sounds like bass, brass, bells, chimes, toms, vibraphone, synth pads…
EPS XS works on iPhone 5/4/4S and iPod Touch 5th/4th Generation. It will work on the iPhone 3GS with only 4 voices and slow GUI (but with MIDI is still supported).
