Hi Audrey
As I understand it the createsongstyles site was set up by Ron Phillipchuk primarily for folk to share their creative abilities in producing styles for many different makes of keyboards by uploading them to one place. We cannot do that on Synthzone to the best of my knowledge, can we?
Certainly since it opened earlier this year there have been close to a thousand members joined worldwide which points to it being of considerable interest.
