I have tried all kinds of boards through the Vent with varying degrees of success.

First, I have never found an instance where there was no improvement, providing you can isolate the pure wavforms.
You do not want any mod effects in the sample. The quality varies from board to board, so that you get an accurate sim of varying quality.

Second is, ideally, having a separate aux out for the organ. The G70, for example, has good organ tones but you can't send them out separately. The KN7000 has fairly good sound and separate outs. The Korg is new to me, but have separated the organ with good results. The best is the Audya, which has good preset organ patches but lousy drawbar sim(IMHO). I use the vent with the Audya all the time.

One can use the vent without a separate out, but you have to remember to punch the bypass switch for non organ sounds.

You are one of the few to comment on this great module. I extolled it's virtues a year ago when I first got it. Nobody paid any attention to the post.

After I get better acquainted with the KMA and PS60, I will post a video on my Youtube channel.

As for vArranger, I think it is the best arranger software out there. I trust it to be absolutely stable and great fun to take out. Dan is adding features faster than I can keep up with them

I don't think I will ever use any one thing all the time. I am a gear slut and love trying out new combo's on the audience. One certainly does not get as proficient with one instrument that way, but it is a helluva ride.
Thanks for asking.
