Interesting. Someone commented that my keyboard looks like a cockpit of a plane (I wouldn't know) and I told them that every little button has a purpose.
I use these buttons extensively. That is why they are there - and why the layout is ergonomic for live players. Switching up on the fly makes for a whole new level of playing.
Try everything, use every button. Make a song a song and not a boring, repetitive boom box....
Still wishing there where even more buttons for certain functions ... and some programmable encoders... good ideas for a pa5x.
But we should not forget we have grown with all these features, and to us they have a very logicalmlayout....but they can be quite confusing for people that are not acustomed to arrangers, even musicians...
