Hello Tekker...
Thank you for being so kind and providing me with all this usefull feedback.I really appreciate dedicating some of your time for me.Thank you so much,once more!!
The info is very useful.It took me a bit(about 20 minutes!

)to go through your answer.I guess it will take me even more to figure out exactly what is going on when the time comes.At the moment,I am waiting for a cable with two jacks(stereo-that will come from my processor)and another one for my sound card.Only when I get my hands on it I will be able to start experimenting with the recording process.By the way,I guess it won't be a problem using the effects from my processor to record music,is this correct?...Here is a question for you.Would you recommend me to buy the Reaper program with 50 $ or stay with the demo?In a way I know that the demo can't be like the whole program(usually demos don't include the whole program as far as I know),but anyway I would like your opinion on that.The second question is that.Could I bother you some more in the future if I get stuck somewhere along the way?You are just the person that I was looking for and with your help I could master the recording process like a pro( I hope I am not over-confident)...
Thank you once more for your time and for the really useful info...
Sicerelly yours,
Theo
