..is the KORG OS that difficult to learn?
Coming from the briliant Technics OS (during many years) I've found that convert to Ketron, Korg MA and then Yamaha was a kind of nightmare.
But, at the end I think it's more the willing to learn and adapt rather than the difficulty.
Imagine if there all that sudden was only a totally new OS whatever keyboard we bougt? Would that be a reason enough to just hold on to the "old" we have, or would we jump on board to the future?
Nowadays I'm not digging too much into all technical "goodies", but mostly find a suitable (hopefully good sounding) style and play whatever comes to my mind.
No gigging and just play as a hobby at home is great, and I think it won't be too difficult to get started withe the PA4X, whenever it will be...
