Hi TGV. You have a lot of questions here. My suggestion is to separate them and put them in the regular BIAB forum where they will get more attention from other users.

Since you have SONAR, yes, give Drag & Drop a try. I go into BIAB Plug-in Mode and then drag the Combo button into the SONAR window of a blank project, go get a drink, and come back and it's done. Magnificent tool, this plug-in mode; much easier and faster than any other way I've tried (and there are several other ways to do it).

If you run BIAB and SONAR at the same time, both cannot use ASIO drivers. Change BIAB to MME (which is really WDM).

In my experience, choosing ASIO or WDM makes absolutely no difference in the sound quality. The reason for using ASIO is to reduce recording latency. Some devices work better with one or the other, but that's because of the quality of the drivers supplied by the manufacturer.

Didn't know if you knew that what PG Music calls a 4-bar ending is really a 2-bar ending with 2 more measures for decay. This feature was added recently.

Yes, I am aware increasing the delay setting at the end increased your cut-off. You explained it very clearly. I don't use Rendering (since I use Drag & Drop). You might want to contact PG Music Support about that one if it stall happens after a Return to Factory Settings.

As to the Boss and Ketron questions, as well as the rendering problem, again, you will find other users in the regular BIAB forum who have that equipment and can help you. You will get better support there, than here in the Wishlist.

Good luck!
