Some great info from all the responses above - many thanks. So two buttons and you're in to the +/- ..........hmmmm, that's not really a problem. Sorry to labour this point but are the two button presses immediate? Sometimes my experience on other boards are that they can be a bit laggy but is it instant on the PX5S? Also, if I did assign transpose to one of the sliders - I'm not sure if I'm reading it right but I can't just change sounds as normal and always have the transpose assigned to a particular slider - but if I have say piano and brass I would need to go in and set both of them up individually prior. If I change sound then the slider transpose reverts back to normal unless pre-programmed for that sound also? Sorry for going on, just want to get it clear. It seems the transpose function isn't as much of an issue as I previously thought - but it is a shame that Casio didn't have transpose +/- dedicated on the board and of course allow a proper expression pedal to be used. As I said, this stage piano/controller gets great reviews but things like that do bug the life out of me because they "seem" to be relatively minor and surely should have been included. One other thing I will say is that this forum seems very active. A definite plus if I decide to go ahead with purchasing. Always good to see. I actually said to a friend last night..........."I never thought I would say this................but I'm close to buying a Casio!!".........his response was but I assured him that "Casio seem to be doing a Skoda" I'm sure there have been plenty of decent boards out over the past few years but sometimes that stigma (which is probably unfounded from the get go) is hard to shake off. But with a quality stage piano/controller like the PX5S sitting at such an enticing price point hopefully the brand gets the credit it deserves.
