Sorry for a late reply or a follow up, but the cost is greater than say One Man Ban version 11 or 12. This has been around for a long time now. I haven't tried the Trial as yet but it looks interesting. It is good that you can save as Yamaha® Style format (SFF 1) to play on your Yamaha keyboard too.

Do you have it and how do you find it?
