So far, I've always avoided arranger keyboards. A mistake. The Yamaha PSR-SX600 helped me through the gloomy Corona period. He doesn't want to be a synthesizer and that's a good thing, because the solo sounds (saxophone, acoustic guitar) complement each other ideally with really "fat" sounding accompaniment rhythms. If you thin out the instruments there and press all the drum variations, you get a transparent, lively sound. It's like going karting 😊
