Don,

The Wersi is already setup OOTB to do what any other arranger can do and more. Their control surface is excellent and the use of the touch screen, knobs, buttons, and sliders makes it very easy to operate. It's what sets Wersi apart from every other manufacturer that has tried to bring a PC based system to the masses. Only Korg came close with the Oasys but Korg castrated the Oasys by not making it open to third party software. Had Korg made the Oasys truly open as originally touted, I'd have kept mine.

The Wersi Sonic is a huge leap forward with OAS. The sheer CPU power under the hood compared to any other keyboard or arranger is staggering. If Music Store updates the sound library with more sounds and integrates additional VST's as stock, it will be a monster synthesizer/arranger/workstation. I can't wait to see the final specs and hear the finished product.
