I have been building my own home studio of sorts for the past few months. It started with a copy of Reason, on special offer with a 25-key controller keyboard.
I also now have Cubase and SONAR, and some outboard gear too. I can record proper like.
I still use Reason more than any other software on my computer. The fact that it emulates real devices has taught me a lot about the way effects, compressors, EQs, etc, work.
If you want to teach music tech to yourself, start on Reason.
