SI Drums

I'm new to all this production stuff but I thought it wastime to get into the 21st century , so I bought myself a Roland PRO 300 c/w Cakewalk SOnar LE 8.5 . I asked the guy in the shop if it would work on my laptop ( a Dell xps l511z with windows 7 64bit OS) I also bought a Samson G Track microphone) My objective isnt to become a producer, just to be able to layer up my worktapes a little better than just guitar vox on my phone.
I've read the tutorials and tried finding one a basic beginners video on the net , which there are a few, but what they all take for granted is that one knows the terminology and so they tend to miss out the really , seemingly obvious first steps.
So I have managed to set it all up ( I think) and I have attempted my first guitar vocal, which seems to be ok , though I havent spent lots of time on it yet as I wanted to get a drum track down first and start adding instruments before I record a vocal and start putting extra effects in. My problem is this : ( I've bullett pointed what I'm doing so someone could perhaps see if I've done something wrong):
!

• I right click on the desk top icon for sonar LE and it has an option to “run as administrator” so I click it
• I notice comes up asking me if I want cakewalk to make changes to this computer so I click yes and Sonar opens
• I click open a new project from the start menu and a box opens up with a series of Templates , I give it a name and choose “normal “ and click ok
• two tracks come up – 1 is Midi, the other is Audio – I have my Roland PRO 300 plugged in so I test the keys and it plays ok
• I dont have my mic plugged in at the moment so I’m not going to test the audio just yet , though I have tested it previously and all seems fine but for the purposes of this email, I want to make sure I can enter synths from the programmes in Cakewalk at least ( I’m sure I’ll be asking more questions and studying more tutorials once I get onto adding effects but for now , I simply want to get started by putting down a drum track
• Nest , I click on insert/ soft synths/ SI Drums and a dialogue box comes up , so I Tick “simple instrument track” and “synth Property page” and “recall assignment controls” and click OK
• Si Drums opens up and a new track is entered on the track view
• I check the settings of the track – input says omni and is ticked none , output says “master” and then I notice there is a setting for “CH” and a list of SI drum kits is available , so I click on number 14 drum kit
• I then go to the drum kit panel and click soul& funk , I click classic, loop and play, I also drag “classic “ into on of the 4 pads on the bottom left hand side of the panel and the full drum kit starts to play in a loop. If I turn loop off and click the pad , it plays for around 1 measure
• I then click and drag “classic” into my track view and click play – The track plays for a full measure, BUT at around half the TEMPO and not the full kit seems to play
• So this is where I’m lost !
• I’ve tried highlighting each of the drums used in the sequence and dragging the “classic “ across, once for each highlight , Ive tried changing the tempo – If I shorted the clip to half a measure, it plays correctly but when I copy and past that or try to open it up , to say 3 measures, it plays random parts of the loop and not all the drum sequence together.
• I have tried going into my programme files and running SI Drums as administrator separately but that doesnt seem to work

That’s as far as I can get without spending hours going back and forth between irrelevant tutorials and reading the help sections and forums , restarting and opening more new projects. I've tried uninstalling and re installing.  All to no avail.

Hi Greg
Thank you for taking the trouble to reply, I really am a beginner so I'm a little bamboozled by all the jargon - There was no option for Mic so I selected USB device hoping that might work and it seems  to have worked so I'll have a little play with it and see where I get stuck next. I dont know what an ASIO driver is or where to look for that either  and I'm not sure what you mean by Simple Instrument track being different to the others as I dont know what any of the other optons do !
I thought you could just plug these things in and they work - everyone says how easy this production is to pick up but it seems everytime you click anything, you have to change some setting or other or install another driver.
All very alien to me but I'll persevere and see where I get to :-)
Thanks again for your replay - onward and upward !
