1. More accesible FX - When playing live I don't have the time to click the FX button, slide the fader of the one I want and press on - I need the FX already there, and the abilty to MIDI learn the FX parameters so I can assign them to my BCD2000. My suggestion for this would be:
a. To have a little 'FX Box' for each deck - containing 2-3 drop down menu's (for those wanting to use more than one effect at a time), where you can select what FX you want to use (the drop down menu's could be scrollable with a couple of MIDI Learned buttons

).
b. A small 'On' button next to each of these drop-down menu's.
c. If required a couple of FX parameter knobs underneath the drop down menu's.
I am only suggesting this as part of Xylio's included FX. From a DJing point of view it would be a lot better for me for this to be implemented, and perhaps support for third-party VST's to be dropped as I never need it, but that's just me maybe...
2. The ability to MIDI Learn the control of playlists etc, so I can select songs from my hardware and not have to use the mouse every time.
That's it for now, if I think of anything else I will come back with it. Other than those things - version 1.5.1 and version 2.0 have been rock solid! I've dj'd for many many many hours without a single thing going wrong. Big Big thanks to Xylio for this!
