It’s relatively straightforward (Applies whether you have OAS, OAX, or the Pegasus Wing, hence a number of uses of OAS/Wing have done it instead of getting a Sonic) as the sound board and Midi are separate components which you just assign vArranger to.
External modules are similar; you just have more limited control of them on OAS and the Pegasus Wing.
Why people waste their money on a Sonic when they are going to use vArranger and an external module is beyond me, (A controller keyboard(s) is much more beneficial) still it’s their money so if they want to splash it on unnecessary equipment, why not.

Maybe because they love the organ part of the Wersi..
But don’t like the arranger part?
Just having all those yamaha, korg, Roland and ketron styles and sounding great witouth the need of edditing is worth a lot to many people..
If integration is flawlesly, and all the OAX arranger buttons work like with a build in style.. V-arranger should be a huge asset..with the high end Wersi organ styles. As long as you get the same experience(controlls) as with native Wersi styles, its perfect.. however if it requires lots of indirect actions, i would grow tired of it quite fast..
