Thanks for your reply. That's really a pity as this feature is crucial for me!
I would use this feature to check if one or especially a group of effects would sound good on an incoming track, but I would also use it for testing effects on a master track by doubling the master track.
Often, especially when using new effects or more effects together I am not 100% sure how they will sound when applied to my current playing track(s). So this feature would allow me to test effect combinations on the fly, avoiding thereby effect usages that don't fit well or effects overuse.
I don't think I am the only user that is interested in such a feature, because I found similar requests also in other DJ software forums. See:
I also wanted to add that I just tested pre-listening of effects on the demo version of djay pro (Windows version) and it worked perfectly...
So, I really hope this feature will get included in future version of Cross DJ as for the rest I still think it's a great DJ software!
Best regards ;-)
