Hey all, sorry for the newb question. I’m a guitarist that wants to get a cheap used keyboard for my little one to play on. He’s 5 so I don’t want to spend much, but he loves the arpeggio function on the DAW workstation in my studio…(makes him sound like he is doing a lot without much input). Is there a lower level Casio, yamaha, etc. with built-in speakers that has an arpeggio function? Thanks in advance for any helpful input.
