Practice Player Live Midi +Usb – 2.5.6.4

As far as I've tested, I'd say USB output may be ok but USB input is not practical unless you have android device with very low input latency like Galaxy Nexus or Nexus 10. Pls. Let me know if you find Android device which have similar input latency as Galaxy Nexus or Nexus 10. Connect external midi instrument and play it, then sounds are now from connected midi instrument.
