How to remove empty items

[Nubeat7]

i did this multifxselector for my fx matrix it is fully working and done for a fx matrix so the "noFX" is different for every selector!! at the int-out it is 7, 8, 9, 10, 11, 12 and 1 -6 dots for the string outs if you want to use the string out, to keep a seperate noFX channel for every fx to avoid feedbackloops thruogh the same channel when selecting noFX on more channels, did i described it clear?
I found out that the matrix is acting much faster with just one character (nr) than with long string words thats why i have the int outs...

just test the outputs out and you will see what i mean

there is also everything saveable in the presets!

think it took me 2 weeks of headache to do this, maybe there is also an easier way to do this...

specially the fiddeling around with the gsub to clean the fx strings for the droplist could be done in a more elegant way i think ..
