Bard macro/song question

[netchayev]

Hi!

I have 4 macros set up on my keys 1-4. A simple Stopcast macro so I dont have to doubletap the buttons, and to play each of 4 songs.

My problem is when I get interuppted or stunned my keys dont work for a few seconds.
I can click the spells manually and they can be cast instantly, but I have to wait maybe 3 seconds before my macro keys will work.

What am I doing wrong here ?
