Yes I know but you need a controller, sound source, pc or labtop etc to get Varranger too work and sound properly. A hardware arranger has anything you need in one and is much user friendly.
And a Korg PA50 or Micro Arranger are cheaper then Varranger
Ditto. Bear in mind though, a Pa3X costs Thousands of dollars, VArranger costs Hundreds.
I have Varranger and although I like it it doesn�t come close to my PA3X.
