I just remembered that there’s a site that will speed things up for you with a series of short videos that many watch.
[Short as in 4-15 minutes long each.]
Once there, you have 3 options:
- Buy the videos outright and watch them where & when you want.
- Pay $15.00 and watch everything on their site for a month.
- Pay $150.00 and watch everything on their site for a year.
[$99.00 sale once in a while - usually at the end of the year.]
The Cubase 7 videos can easily be viewed in one sitting of 2-3 hours, or across a day or two [or at any pace you like].
Ideally, you would have Cubase up & running as you watch along and emulate what’s being done & shown in the video[s] for hands on practice & visual on-screen results.
Then you could view the Cubase 7.5 ones if you choose to upgrade.
You can also find some things on Youtube as suggested above, although for the $15, I would go with Groove3 first, as they start with the basics and progress along logically & categorically.
Main Access Page
22 Videos - 2.5 Hours
21 Videos - 3 Hours
30 Videos - 3 Hours, 16 Minutes
So that’s 73 videos almost 9 hours in total for just $15.00. 
[You could easily watch them again & again within the one-month time frame.]
Hope this helps.
By the way, I commend you on your chosen desire of wanting to learn Cubase 7.
Some consider it to be one of the harder DAWs out there, although I find it easier than my first 2 DAWs.
It certainly has much to offer, although myself, I may never use some of the many options & features that it has but it’s nice to know they’re there if ever needed.
Feel free to ask more, if needed.
