Default QLAB please help with a simple crossfade

OK so I've been using QLab for a little while and first time I used it for a show last year it wowed people who were used to hearing playout done from tracks dubbed onto CD.
I thought I was happy with it too ... until I came to putting together something for my next show which will include .... a crossfade!
(now I should point out that I've worked in radio and audio for a long time ... when I started we wrote on typewriters and cut tape with a blade)
I can quite happily put in the fade cue to bring down CUE1 say. But everytime I try to put in the fade cue to bring up CUE2 all it does is start CUE2 and fade it out. Not a lot of use. Am I missing something glaringly obvious? (probably)
Bob

First off do you have V1 or V2? Doing this from memory so bear with me...

For V2, what I used to do (I think) was create a group which would all the cues at the same time, the fade up and the fade down cue. I think the group was called a simultaneous group... If thats not it, post back and we can work through it.

Thanks for getting on to this so quickly. I'm using version one of Qlab so it's the really simple one. Which was why I thought a cross fade would be a really simple thing to do.
So ... it's a music crossfade I want to do with CUE1 fading down as CUE2 fades up.

I sincerely apologize if I'm telling you things you already know, but let me try to explain how I do it and you can compare that with what you are doing. The basic concept is the same for v1 and v2.

Ok, so you have your first q, (we will call it qA) and your second q (which we will call qB). You want to simultaneously fade out qA while fading in qB.

You start with qA set to whatever level you want it to play at. Then you put in a fade to fade it all the way out. From your post, I'm guessing you already understand how to do this.

Then you make that fade auto continue into playing qB. qB's volume level needs to be set all the way down.

qB will also auto continue into another fade. This fade will affect qB. Its volume level needs to be set to whatever volume you want qB to fade up to.

So your playlist will look like:

1 qA
2 FADE OUT qA (auto con)
3 qB (auto con)
4 FADE IN qB


This means that when you click on the fade out (#2) then all at once you are fading out the first song, starting the second song (with the volume all the way down) and then fading that volume up to the level you want it at.
Does that make sense? Does that fix your problem, or is that what you were already trying?
