Welcome, Ranger. Esp. to the Cake family. As you have discovered, Music Creator is Cake's intro DAW for recording MIDI and audio and manipulating them (my favorite analogy is the word processor). Z3TA 2 is Cake's virtual analog (VA) synth, where a few sample wave shapes can be manipulated just like the analog synth of yore. Soundcloud (and soundclick) are websites where you can post your songs or sounds and others can play them. You basically have everything you need to create songs and publish them.
As to your sound, you can post links once you've posted 25 ... posts. That is to help w/ the spam we get on site. You'll find a lot of good people on the Songs forum. Most are guitar-based, but they don't bite if you are more synth based. In fact, even tho they are limited to 6 strings, they still have very good ideas about sound and song structure and performance and the engineering side of things.
I couldn't track down your sound, google kept sending me to game descriptions. Soundcloud makes it easy for us to go to one place and hear what you are talking about. Hopefully, you'll get that sorted out.
Most importantly, have ya some fun.
