Failing at Bard hot swapping wep/instruments

[VincentVolaju]

So I was told I could hot swap my wep and instruments with just normal hot keys like I use for skills etc., but it doesnt seem to be working. Im doing the following, tell me if I am wrong.

I got 3 empty slots in my inventory
Put Lute/Drums in 2, leave the 3rd blank
Click/Drag the inventory slots with the instruments on them to my hotbar
Place on hotkeys bound to #4 and 5.
Take weapon off, press 4 or 5 and nothing happens
Right click the hotkey on 4 and 5, nothing happens.

What am I doin wrong?

Someone in game said to look into a UI, but I am pretty used to my UI. I thought there was a way to do this with just the normal UI?
