Beginning is never easy...Be aware that it will take several years before it will sound good. Reason is a good starting point as it involves everything that a real studio has to offer and it's cheap. A hardware unit may bring you additional flexibility but will introduce new difficulties (MIDI, audio signals etc...) Because you really don't have a use for a 3 grand synth, go rather with a hardware RMX1 box or an MPC if you have some more dosh.

Cubase is a wonderful program but it's way over the top for someone just beginning. Cubasis (a countdown package) will give you all the basics without making it too difficult with a lot of extra functions. With other words.. cubase (every top sequencer BTW) has a very steep learning curve.

The only true advice I can give to beginners is read read read and read some more. Read everything you can lay your hands on that relies to a topic of music production. Get familiar with the jargon, processes, stages in production and techniques. just you'll recognize a sequencer when you see it....and more important.. you'll know what it does.

PS: I noticed all the DJ prefixes welcome to the other side of the vinyl..
