I have tweaked lots of things on my pa1x to the point that it was fully personalised and custom set up for me . It’s one of the key reasons I held and actually still have it after over 12 years .

I now have the pa4x and I have deliberately had to discipline myself from spending too much time just exploring what can be done as opposed to actually getting something done !

These instruments are so deep you really don’t need another keyboard for a life time .

I kind of agree with chas and DNJ. I am really critical when it comes to my drum and bass programming . They are the heart of the kind of music I love to play :gospel and funk so getting the right sound to start with is foundational .

However if music is not your full time endeavour , you have to be economic with your time . Playing and refining your performance skills trumps tweaking for me . But both are highly enjoyable !
