My main struggle with mixing is to get drums and vocals pushed back in the mix.
every other instrument seem to sit well back, but drums almost jump out of the speakers
also vocals. I know i can use a bit of delay for starters at least on vocals to bring it a bit back
and some reverb, but i dont not completely get what i want.

For drums its hard to use any delay, because of the beat that will double up,even at low setting
on the delay. reverb helps a bit but not mutch.

How can i get upfront sound of Drums and vocals to sit back in the mix ?

Are you using midi drums or are you mic'ing your own?
 
If midi, you should be able to move the Room sliders up and down on the mixer within you midi drum program.  Also play with the overheads some.  Reverb is also used to move sounds forward or back.  I have not used the R-Mix plug at all, but that might also be able to assist in placement of the instruments.  Maybe someone else has worked with that.

Midi drums like session drummer 3, that's included in sonar X3d
there's no overhead etc on drums like that, that limits that option.

Or you can reduce the level of the offending drum(s). In particular, the snare in SD3 and many other drum synths is overly aggressive for my taste.
If the drum is too loud, simply adding more reverb will just leave you with a loud, muddy drum.
I treat most instruments, live and soft synth, in generally the same way.
I'll leave the track output dry, and use a pre-fader send to a bus where the reverb is. Depending on effects, such as an amp sim, I may send the track output to a second bus before making the split.
This way, I can use the reverb to shape the space, and raise or lower the track level to move the dry instrument forward and back in that space. 
Careful EQ and possible judicious use of limiters can help fine tune the overall balance.

EQ. More mid/low end brings the drums/vocals forward. Reverse to push them back. Don't overdo it or it will sound like you recorded them in a can.

Thanks a lot, will try that.

When we hear something from far away the highs are rolled off, in general.  If you want to push the drums and vocals back rolling off the highs a little should help, along w/ reverb w/ a longer delay time. 
 
Delay, esp. on percussive stuff, is usually a bad idea.  Even w/ tempo synced effects you get weird doubling and flanging.
 
But if you want something to sound not so upfront, the easiest thing to do is to lower the volume.  For vocals and drums, even, this usually means automation so vocals don't poke out too far above the soundscape or get lost below it.  Often a couple of dBs can make a dramatic difference so it just feels right.

I'm with AT on this one - if it's too loud, turn it down!
 
What happens if you reduce the level of your drum bus in 1dB increments? Does this get you anywhere closer?
You should, if your kit is balanced properly, be able to lower the drum bus without having to tweak the levels of individual drums. Theoretically, you would also have to adjust your send levels to any drum reverb bus as presuambly they'd be set to post and simply lowering the buss won't compensate for this and you'd end up with less of the dry signal with the same amount of reverb. This could however, work to your advantage because as mentioned above, adding more reverb tends to push sounds back in the mix, though clearly you would probably want to tweak the sends afterwards.
 
Also, don't be afraid to experiment with applying large amounts of EQ to your reverb buss. Rolling off the highs can really help here
 
Alternatively, you can start lowering individual kit pieces - using ctrl across multiple grouped faders will let you reduce all faders at the same time and proportionally.
 
One final thought. Take a long hard look at your velocities on your midi tracks. If they're all upwards of 100 or so, I'd seriously consider reducing them to round the 80 mark. Scale Velocity is perfect for this, as can the Event Inspector.

I have gone on about the small Auratone speaker concept but I want to remind people again of how good it can be.  I use a single small Auratone type speaker being fed with the L+R signal. I listen to it down at quite low volume.
 
I find it is excellent for correctly setting all the things mentioned here. Drum levels, vocal levels you name it.  It also seems to really highlight problems within a drum mix as well.  If any kit piece is over load then it seems to really stand out in the small speaker. Becomes very obvious.
 
If you have got your buses set up correctly then in the end you only need to fine tune buss levels and the small spekaer also makes that very easy.  I find it is the only way to set vocal levels over the instruments and also drum levels with respect to everything else too.  Once you put it all up on your main speakers again what you will be rewarded with is a perfect mix every time.  It also translates really well too.
 
Sometimes listening to a mix on your mains (especially up a little louder) for too long can almost make it impossible to get things right.  Yet when the whole mix is bottlenecked into something like this down at low volume it all becomes very clear and easy.
 
 

    Moving Drums back in the Mix, ( what i learned ) by Jan Ståle Krakeli

1. adjust the balance / level of each drum and " Overhead's "
    EQ the drums, and apply some compression if needed.

2. " Live drums : if u have the drum's room-mic'd
    skip step (3.) and use the room sound of the mic's "
    be sure to EQ OH's as well, for a nice room sound.
   
    or skip the room mic's, if you don't wanna use it
    and apply step 3.

3. Insert a Reverb on the ( track ) / ( Drum BUSS ), blend dry and wet effect.
    the reverb effect is not gonna be " heared "
    but more to widen the sound, and it shal still
    sound " dry " and not that " in your face " type sound
    Important, use a " very natural " sounding Room Reverb for this.

    Why step 3 ?
    cause it will be easier to move the drum's back
    because they'r not so upfront sounding
    and you don't need that much, main Reverb send
    it will sound more natural, and not to " over-done "

4. Use a " pre-fader send " to a buss where the main reverb is.
    ( EQ the send Reverb of your taste )

5. Use the reverb send to shape the space, and and lower the track level
    of the drum(s) / drum buss, to move the " dry instrument "
    forward and back in that space.

    For vocals
    you can apply mainly the same procedure, but also add a Delay FX send.
    An " tempo" based delay, it also widens and push the sound back / to the side's
   
    we know that most of the energy of a sound
    is present in the (M) of M/S signal flow.

    Drums, Bass and vocal is mostly present there.

    Thank's for all the great feedback, a truly great forum
