I do believe that playing other instruments help a lot when emulating those sounds and arrangements on an arranger keyboard.
I started out playing Trumpet, then in college played Bass Guitar, then lead Guitar, then drums. Then the band back home needed an organ player about the time I graduated so I bought one and learned to play on the bandstand mostly. We had always had a piano and/or organ at home because my mom played, but I really never played them except to fool around a little.
The day after arrangers were invented, I sold my last big old huge heavy ugly organ, leslie, bench, pedals, dollies, etc., and never looked back.
Wish I had learned Sax at some point! Love to hear 'em.
