I'm not sure I understand. If you want to have a URL link to your song on JamStudio.com, do the following (you won't be able to add tracks to this):
- Login on JamStudio.com and save your song
- Click Share and email yourself your song
- Copy the link in the email you receive and paste it in a post on the forum. This will allow others to play with your instrumentation, chord progressions, etc. on JamStudio.com.
If you want to upload the actual file to the Internet (i.e., and MP3 with vocals, other instruments, etc.), you can use a third-party host, like
Box.net, like I mentioned above in the FAQ.
Does that answer your question?
