My training was on piano with that said I’m guessing somewhere around 2006-2007 when I started gigging I felt I had to have an 88 key instrument with arranger features. I think for the first few months I used a Yamaha DGX 5xx that didn’t do it for me, then I went with a Casio 88 key piano with arranger features. That didn’t do it either so I added a PSR 3000 and used midi to connect it to the Casio..............I got tired of carrying 2 keyboards around it just wasn’t worth and adjusted to using an arranger like an arranger and not a piano. Just too much work for one hour gigs.
