NEVER MIND SOLVED- one effect in FX stack at a time?

[matthewchapman]

I don't know what I pushed, but right now when I add an effect to the FX stack, it deletes the previous effect. I used to be able to add multiple FX at a time then preview and apply.

Is this a setting? I can't find it.

Thanks!
matt

EDIT - Oh i accidentally switched to single effect. 6 years and I have never seen that!
