Do you mean exporting as audio file or making save file?

Only way to export as audio is to record from headphone output to external recorder/computer. Emulator makes save file so you can store your tunes in memory stick or other storage media.

I love LSDJ, you can get really weird sounds out of it, its capable of doing one of hardest gabber bass drums in the world

Any news about trackers on n900? I find out that MilkyTracker has been ported to diablo...

I've uploaded a port of milkytracker for n900 to extras-devel.
