Thanks for your reply.
Any keyboard sold would come with some sort of pamphlet. I've seen it somewhere on-line but one must part with a tenner!
By the way Mick MacNeil used one on the first three SM albums. Ultravox, Magazine, SM...and Monument/Party Fears Three cannot go wrong. Best string machine title?!
To get the Ultravox effect would it be the Yamaha analogue delay, flanger, phaser, space echo or just a good amp?
