The Sound of Overbridge is too small

Elektron Gear Digitakt
#1

Hello, i use digitakt with overbridge,

8tracks are dry
1track is wet (fx track) in ableton live

But Sound of overbridge is too small,

for example When i first mix, i set the kick to -6db, but kick is almost -25db peak so it is hard to adjust -6db.

So When you first mix, do you use group tracks to raise the volume at once? Give me mixing tip plz.

I set tr and samle level to max, and amp to max and have no problems, when i start mixing , i usually have to pull signal down, and up with -12 overall, like recommended.

How do you usually raise 12db all at once?
