SYNTENDO

"Do you have fond memories of the 8-Bit Nintendo's music?
Do you wish there was a VST that you could use to make music just like that?
Do you miss the glory days of Sunsoft?
Do you like bleeps and bloops more than granular synthesis or spectrum modulation?
Do you believe Shigeru Miyamoto sold his soul to the devil?
Do you enjoy fondling small, rectangular, multi-buttoned objects?
Do you dream in 64 colors, sometimes swapping mappers accidentally?
Do you consider Mr. Gimmick a dear, close personal friend?
Do you think 8 step sequencers are "just right"?

Do you just really, really, really like free synths?

If you answered yes to any of the questions above,
than Syntendo was made for you!"
