Cryologic is a soundfont library and an advanced soundfont player developed in VST format, developed by MaxSynths.
A free version of Cryologic is now available for download on the MaxSynths website, including a free 142MB sound library (16 presets in total).
Here’s a quote from MaxSynths:
This version was previously released as a special version for a magazine, now I’ve decided to use it as the official “demo version” and share it with the rest of the world.
Apart from being limited to 16 presets selected from the full library, the SF-load function for oscillators 2 and 3 is disabled. Other than this there are no other limitations.
