O Lord, your pieces of advice are the kindest and most valuable ever!

Maybe, I myself am so foolish, but all the modern synths and not so much modern ones are so digitalised from A to Z Maybe, VSTi's would be better to me. Since I just want to turn knobs without programing. Or just use them in basic sounds and treat them with effect devices.

Again, the Korg X50 manual is not that much understandable to make use of it, cause the writers were completely aware of what they were writing about while the readers are not that much at all!

Say, they write "make use of the Copy utility" to double a preset, but they have not said a word where an empty preset is available. That's just an example.
