I'll tell you something:

If the implementation of VSTi will be comprehensive and will cover as many as the options is possible (even centered it around one particular VSTi) this could really bring the new era in arranger world! It's not gonna be able to compete right immediately with TOTL arrangers, but it will come.

I see it like that at least - I wish a could have a software arranger that will play my favourite style with my favourite sounds!

So, keep up the good work!
