1) There's Youtube, I believe anyone can upload a "video" file with NO video at all...equip it with the required keywords, like "style" "tyros" "G70" and so on, and make it's presence known to the others here

2) Someone (may be you Diki), set up a GMAIL account, using a unique and easy to remember name like "ARRANGER-STYLE-AUDIO-CLIPS" and "SYNTHZONE" as password, and everyone should e-mail there his/her clips for all to log on and hear, again with reasonable subject lines like "Yamaha Tyros Beguine 1", so everyone logging in will be able to find what he wants and hear it.
