another point.
For field Composer, I would like the field to display the combination of:
current value if not blank
And the value of the field Composer2.
Is it possible ?
thanks

I found the solution to combine action through FAQ...so great !!
I have another question. I want to have the bpm displayed on 3 digits..
When bpm is below 100, I want to display for example 094... how can I do that ?
thanks

You can use the $num function for this.
$num(%bpm%,3)

Try Format Tag field for COMPOSER
Format string: [%composer%]%composer2%

I would like to thank you all for your support! I have made great progress and automatize my Tag editing process...it will save me a lot of time when I will tag every new track.
