There are many configurable options on your account.
This article looks at the options you have to become 'Search-able' or to present yourself to the public.
Firstly, navigate to your account (top right).
Level one profile
... find the 'EDIT' tab, under this you will see 'Artist Details'. If you visit this page you can include details about your instruments, experience and studio. This is what people will see if you don't have an 'Artist Profile'...
Artist Profile (My Page)
If you click on My Page you can enter all this information and upload a picture. This will be nicely presented if anyone clicks your name. And your picture will appear as a thumbnail next to anything else to create on here.
Upload Music
That is what you are here for! isn't it?
You can attach a music file to the upload field in 'Artist Profile', but this will just be a download-able file. Instead go to CREATE >>> 'Audio'
and upload your music track. AUDIO TYPE - select 'profile demo', it WILL appear on your profile.
Upload Picture (alternative option)
Go to CREATE >>> 'Image'
This image will have an automatic thumbnail created which you can attach to other creations such as audio files, blogs, forum topics etc etc.
Did I say it would be easy?
