Music creation software?

My friends and I are attempting to make a video game and to do so we need music. We've decided that creating our own is our best option and are now looking for the right software for the job (Which is why I've come to Y!A).

So I guess I should probably tell you what we're looking for...

Ideally we want something that can do instrumental as well as techno music. Specific instruments might include piano, drums, and various types of guitar (Thought possibly others would also be useful). Even better if you can mix the instrumental w/ the techno but you don't have to. That could give us some really cool effects.

Also, I would most likely be the one doing the music and I don't know much about computers or creating music with computers (My other team mates are handling the coding end, while I do a lot of the conceptual work. None of us really know much about making music). So it would be endlessly helpful if this music creation program was at least moderately easy to use.

Lastly, cost is always a factor. However, I don't want to leave anything off the table. If we can find the right software, we may just have to eat the price. But obviously cheaper is better.

So to sum up what we're looking for:

> Able to create both instrumental and techno

> At least partially user friendly

> Cheaper the better (Though always quality over price)

If anyone has any ideas of what we can use (Literally, anything that even vaguely fits this description would be worth looking into for us), I would really appreciate help with this.
