1. I am mainly needing this software to mix my own music as I am a professional entertainer, can this software be used for that purpose?
Yes. Everyone here uses it for that purpose, as well as recording.
2. I need info on how to fade in and out, blending tracks together, how to add sound effects ect.
Blending tracks together? Once you record something on another track, if it's in time, it should be blended. Maybe I misunderstood...
But to easily fade a track in or out, you hover your cursor over the top left or right corner of an audio clip. When the cursor becomes a triangle, grab it and move the triangle to the left or right, depending on whether it's a fade in or out.
The gray area is the fade out.
What kind of sound effects? In the track pane or the console view, you should see a box labeled FX. That's the effects bin. Right-click in there to bring up a list of available effects. Select the one you want, and most have control panels to choose presets or adjust to your liking. If you don't like that effect, you can right-click it to delete it and try another.
Oh, and welcome to the forum!
Some info on your system would be helpful; what's your operating system? How much RAM does the computer have? Which version of Music Creator did you buy? Do you know what sound card you have?
