== Features ==
Browse through the included sounds and use the 2 octave keypad to trigger notes to produce evolving, rhythmic, or melodic sounds. Create your own sounds with a single button press using the breed feature. When using an iPad, you can delve into a tweakers dream by using the extensive editing features to sculpt sounds to your heart's content (editing features are only available when used on an iPad).

Crystal features both subtractive synthesis and frequency modulation (FM) synthesis. It offers abundant modulation control with over 90 parameters which may be modulated, multi-stage envelopes with graphical editors, extensive tempo sync of envelopes/lforates/delay times, built-in effects for chorus/flanging/comb filtering/echoes, and a band splitter for effects processing by frequency band. Not only that, Crystal has wave sequencing and granular synthesis. The musical applications for Crystal are literally boundless.

== Different Versions ==
There are two different versions of Crystal to choose from, Crystal and Crystal XT, so you can select the one that is best for you. Crystal is the basic version. With this version you can browse sounds, play notes, and create new sounds, taking advantage of its powerful semimodular synthesis engine.

Crystal XT (also available in the app store from Green Oak Software) adds MIDI keyboard input, sharing of sounds with the desktop version and other audio apps, and background audio so you can play Crystal from midi controller apps.

== Notes ==
Important note for iPhone users: Crystal runs on both the iPad and the iPhone. Because of the limited screen space on the iPhone however, the editing pages which contain the edit controls are not available when running on that device. But on the iPhone you can still browse sounds, play notes from the keypad, and create new sounds with the Breed and Design features.
