Many thanks to Rikki; Bluezplayer; and Starkeeper who were kind enough to recognise that if you ain't been there then you don't understand; and it's a great temptation to take advantage of Scott's plea for help headed 'Need soft synth crash course'to educate meself and probably many others 'listening'...Apologies Scott but hopefully you got something out of it too!
Best wishes
Roger M
