Green Oak Software updates Crystal Synth XT for iOS to v2.0.6

Green Oak Software has updated Crystal Synth XT for iOS to v2.0.6.

Crystal Synth XT now includes a piano style keyboard. When used on the iPad, a user now has the option of using either the circular keypad that Crystal has always had, or a traditional piano style 2-octave keyboard. Crystal Synth XT also supports virtual MIDI so it can also be played using any MIDI controller app or an external hardware MIDI keyboard.
