HI Diki

I have never come across a keyboard/organ built from the 90s on; that the style couldn’t be played on later instruments, playing later styles on earlier models is another matter though.
Simplifying a style is always good but, I have found that if you take more than 2 voices (Or sometimes even 1) from the style, the style completely falls apart and is pretty much unusable. (This is particularly noticeable with Yamaha styles)
