Some of my favorite go to styles are conversions, and deeply edited

I use a Roland G70, and many onboard styles are useable for me, but I have favorites, from Korg(20 plus), Technics(6-8), and maybe one or two from Yamaha..

I like Ketron styles but they don't convert well..

Yamaha conversions are poor at best...and I don't like many Yamaha styles to start...actually there are a lot of useless styles.

Technics "jazz" styles are really nice on the G70..using the sounds from Roland they are way better than Technic sounds..

I have to say the Korg conversions are also better on the Roland G70 than on the Korg..I think drums and some other sounds are much better on the G70..

I should mention Roland styles don't convert well to Yamaha either...the common factor is Yamaha..
