Hey, I didn't know which forum to post this in, but I was wondering how to record something in a pregap?
Do you mean pre-gap as in where one song flows straight into another?

I guess you could just record the two songs normally, then when you have finished, take a tiny little snippet of the end of the first song, cut it, then paste it into the start of the second. I don't know what software you're using, otherwise I would have been more specific.

Hope it helps.
