Freeware Veteran Semi-Modular Synthesizer Crystal goes 64 bit Mac/Win | VST/AU
Dec 13, 2010: Crystal goes 64 bit! With version 2.5.0, Crystal is now available as a 64 bit plugin on both Windows and OSX. The OSX installer installs both Audio Unit and VST plugins which are capable of 32 or 64 bit. The Windows download includes both 32 and 64 VST versions, so you can put the appropriate one in your plugins folder.
Crystal is a semi-modular software synthesizer featuring both subtractive synthesis and frequency modulation (FM) synthesis. Crystal offers abundant modulation control with over 90 parameters which may be modulated, multi-stage envelopes with graphical editors, extensive tempo sync of envelopes / LFO rates / 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. http://www.youtube.com/v/IduNXwktVAE?fs=1&hl=en_GB
