Thank you Jupiter, Jonny and Alec for your replies. What a wonderful site you recommended Jupiter- I'll be spending lots of time there. I'm especially interested in "How the brain works" at the moment.I think I can live without a T.V output but it does look as though a USB is a future "MUST".Can it be added on to a normal keyboard- it seems it can be added to a computer.Speed and distance is not really a prime requisite for me, although I get impatient with the K.N 5000 as it takes so long to load a selected song. On my Roland G 800 I can load a disk with more than a dozen songs on it and select and play any one of them with one quick button selection- no separate loading. Why the difference? I suppose each keyboard has its pluses and minuses and you cant have everything, The Roland requires speakers and with 76 keys is too heavy and won't fit in the boot of the car.I like the 76 keys as I use the upper split quite a lot.Nice to put all those fills in with a gloc.Tecnics wins hands down for backup and further understanding and I love the Magazine. Cheers Jean.
