I received it but could not reply*sighs* fu

Ok I emailed you!

I'd keep checking back as well, usually some of the older (no offense sonar vets ;) ) hang around here and give out their wealth of knowledge.

Welcome to Cakewalk Sonar Kamodulation,
 
First I suggest learning as much as possible about Sonar and how things get done in it.
 
YouTube has a bunch of excellent Sonar Tutorials
 
Sonar Tutorials

Groove 3 Has rather good video on CakeWalk Sonar tutorials and they are currently 50% off each video download.
 
More Sonar Tutorials
 
I hope this Helps

Well thank you very much! I will definitely look into groove3! But can any of you help me with this problem?My sister an I's mixes come out really thin on cellphones but they sound good on computers, beats Pills, and headphones. We record in our bedroom so how do we get our mixes to sound good on our mobile phones, like when we watch or listen from YouTube or faceboook?! We are going mad simply because they are so many coverists who mix in their bedrooms and their mixes sound great on cellphones!
 
Why do our mixes sound so thin?!
 
 

Use different monitors when mixing.   I have three different types of monitors to check my mixes.  Two different type of KRK  Monitors V4's  and Rocket 6's and a very small pair of desktop PC monitors,  If I can get the mix to sound great on all three, then I've done my job correctly.  Take all mixes out to the car for a listen or play back on a smaller set of speakers.   You may want to invest in a monitor switching and level control box.
 
I use the Mackie Big Knob for this. 
 
A very inexpensive version of this is the Samson C-Control  $99.00
An imitation version of the Big Kow is the Behringer MONITOR2USB for $199.99
The Mackie Big knob is 299.99  - BIG KNOB
 
 

I use both monitor and headphone. A good headphones like at40 goes a long way for me.

As already mentioned there are a ton of good tutorial vids on YouTube.
 
I'd start, however, with CW's own Cake TV and Sonar University.  Both have tons of videos on a wide variety of topics at every skill level.
 
Don't be put off by the older Sonar X2/X3 videos.  I'd say 90% of the content applies to Sonar 2015.

If you try to get a grasp on everything before you start being productive and laying tracks down , you will probably never get started recording your projects or music for real. I would suggest to start learning by figuring out what you want to do step wise, and learn what you need to know about that particular step before moving on to say, step 2, 3 ,4 ect. , and once you get to the following steps learn about what you need to know to get past that particular step and on to the next. Along with coming back to the forum to ask specific questions about specific steps or issues you might be having. Been here since Sonar 4 Producer, although my post numbers are low due to the new format with subscriptions and registering format etc.  There a lot of knowledgeable and helpful people here. And hopefully I will contribute to being one, to you and others. Stick with it, Sonar is a very good production/recording program.

Sounds like you need the basics on mixing as much as you do on using Sonar.  If your mixes sound thin using Audacity, I don't suspect that will change just by using Sonar.  Pick up a book or some youTubes on mixing (I recommend The Recording Revolution - he has a series of 5-minute videos on youTube for mixing) and learn how to properly use EQ and compression.  Granted, real-time feedback with plug-ins in Sonar will be easier to use than doing it in Audacity.
