I started with the free trial today. It doesn't have ANY soundpools and only one synthesizer: Robota. It won't be much of a trial if that's all I can play with. Is there somewhere to download more soundpools?
There should be a startscreen which tells you to watch the Tutorial Videos and download the content...it was a huge button on the bottom of that screen.
Ah...you do use Music Maker 16, don't you? In Germany they released 16 a few weeks ago...?
You'll find the link in the "Help" area as well (not the help file received by hitting F1, but the menu on the top)
I may be closer to a real answer. In the bottom right corner of the welcome dialog box it has "Download soundpackets..." I think soundpackets are soundpools or soundpackets contain soundpools. I clicked the link that took me to a page that looked like an error; no instructions. But there is a button with an arrow. I clicked the arrow button and it opened a description. I then clicked a second identical arrow button (still no instructions - easy to miss). I had to prove I was human and it started downloading an 87 meg file. It must be on their slowest server because it's saying it will take an hour to download. Yesterday I downloaded the 100 meg app in less than 10 minutes.
If you want truly free loops & sounds (www.looperman.com) I use alot of there loops all free and there's(www.soundsnap.com) also free so there you are. Happy music making
