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.
Crystal for mobile devices comes in two versions:
- Crystal, 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 (available soon for a premium price) adds MIDI keyboard input via the iPad’s camera adapter and sharing of patches with the desktop version.
Crystal runs on both the iPad and the iPhone/iPod Touch and sells (App Store link) for $0.99.
