I've looked on this forum before posting this and I only found one thread about this, which didn't really help me out.

So my question;
How do you translate guitar tabs like this:
Db|------------7-12/-15-12--------------------------14-17-19-15-------|
Ab|----------8-------------13--------------------15-------------------|
E |--------9------------------12--------------14----------------------|
B |------9-----------------------14-10/-12-16-------------------------|
Gb|-7-10--------------------------------------------------------------|
Db|-------------------------------------------------------------------|

To the reason piano roll? I've tried using the convertor on tabnabber (I can't seem to post a link :/)

But the output wasn't very clear :/ (Db, Ab, etc.. I don't know to what it corresponds in Reason (it only has C as far as I know).

Sorry if I didn't made myself clear but (knowing I'm not English speaking) I didn't know how to put my problem into words.

Thanks for those who will try and help.

The problem here is that the string tuning used in your song is Db-Ab-E-B-Gb-Db instead of the standard E-B-G-D-A-E, and tabnapper only works with standard tuning. As it is, its output is garbage.

Luckily, it's just the standard tuning lowered by 3 semitones (frets). So, all you need to do is change your tabs to standard tuning, and in the Capo/Transpose field, enter -3.

e|------------7-12/-15-12--------------------------14-17-19-15-------|
b|----------8-------------13--------------------15-------------------|
g|--------9------------------12--------------14----------------------|
d|------9-----------------------14-10/-12-16-------------------------|
a|-7-10--------------------------------------------------------------|
e|-------------------------------------------------------------------|

This is what you get:

5|---------------C---e--C---------------------------D--F--G--e--------|-
4|---------C-e-G-----------a--e--C---------D--F--b--------------------|-
3|--C-e--G--------------------------a---b-----------------------------|-

Now you can enter them into Reason. Capital letters are sharps (black keys), you can look up the table here:

Thanks I'll be trying it out right away!
