Hi Angel,

here is what Ketron say about the audio loops:

"Audio Loops and New Sounds.
In addition to the well-known timbres of the reference standard (GM), the SD1000 comprises other Sound Banks with lots of characteristic sounds of the conventional families (Pianos, Strings, Sax, and Brass etc).
The top feature of the SD1000 compared with other sound modules is definitely the presence of so many audio Loops (Drum Loops, which can be downloaded free of charge from www.ketron.it)".

So, you have to download them from the Ketron website, whereas the Midjay has them already inside, and we don't know if they are the same, or different ones.
Time will tell...
