Everyone thinks their ‘ethnic’ music is normal music, and other people’s normal music is ethnic!

Given that house and club music is primarily done with drum machines and synths, and Ketron’s thing is primarily live musician music styles, I'm still puzzled as to how you would expect them to include much if any.

If you aren’t into creating your own dance tracks, personally I’d say something with a solid reputation for being supported by third party content for dance loops is what you need, and that’s never really been an arranger thing. Nowadays, it seems like software solutions or hybrids like Maschine and MPC devices get the most content.
