Crystal by Green Oak is a semi-modular software synthesizer featuring 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, granular
synthesis, program morphing, MIDI learn, and imports soundfonts.
