Roland is offering a free collection of sounds for its V-Synth GT synthesizer:

The download adds a synth museum’s worth of sounds to the V-Synth GT, with over 450 recreations of classic analog synthesizers from the ’70s, ’80s, and ’90s plus a host of classic Juno, Jupiter, SH, 303 and D-50 sounds. There are also new filter bank patches specifically designed to control external audio sources.

All patches were designed using the V-Synth GT’s powerful analog modeling technology.
