Squeek d. the korg oasys is not an arranger keyboard and would never be marketed as such. It is fo the most part a studio instrument where latency is simply not an issue. If it had arranger capabilities it too would struggle to meet the reqirements of any arranger layer musician if the best sounds were to be used within the styles. Unfortunately , if you sell anykeyboard on the back of its USP (unique selling proposition) to a market that requires features that he keyboard does not have , there will be a mismatch of expectations . Right now there are serious questons that still need to be answered by Dom before i believe his product will meet my expectations but feel free to sell what you have and purchase an MS and let us know how you get on with it.right now the MS's USP is wasted on me but might be great for others
