[Ardour-Users] Loops in Ardour

[teza]

Hi all, I would like to know if anybody  got troubles while making loops
in Ardour. Consolidate range works when it wants and if I use range tool
to multi-duplicate doesn't work or sometimes. I followed the
instructions in the floss manuel. I am using Ardour 2.8.7 on Ubuntu
Studio.
Is a there a bug? Do I do something wrong? and in this case floss manual
have to be update.
Thanks for your help.
