ok, so I understand that one of the Liontracs instruments can read giga files.

No... all of them can read Giga Files.
All Lionstracs products run on the exact same OS and have all the same features. The only difference between them is the amount of hardware and speed.

Can it read all kind Giga files?


lso, I work a lot with midi files and arrangers. Giga files are not GM compatible, as far as I know...has Liontracs devised a Giga gm module, and how does that sounds?

All Lionstracs keyboards come with Giga Files arranged into a GM Compatible bank of sound.

So your midi files will load directly into the keyboard and play straight away without the need for you to load any software or anything at all. In short, it will read your midi files straight out of the box.
