Good luck with the M50 Stefano! Korg has really put out a winner with that budget workstation.., and YES Korg has amazing Combis. The way you look at those combis is like how Arrangers have OTS. Arrangers you pick a style and the OTS has presets (some good.., some not so good) preassigned to that style through the OTS buttons.
Synths have those Combis..., A good set of patches all assinged with a drum track and killer arps, with preassigned effects routing, ect. Korg IMO has some REALLY good combis.., especially in the orchestral department. So much happening in those..
I'm glad you found which one will work for you. You did your research! That really saves you a lot of headaches and even money down the line. Arrangers are great keyboards..., and they too are good song writing and performing tools. However, an arranger doesn't always fit one's needs. Sometimes you gotta go to the workstations.
