how should be created the wavs from user audio drums, with markers? I have seen that the ones created by ketron have markers

If you know, how to make Drums programming in your DAW (for example Cubase, Logic, etc) you can make export (WAV up 16 Bars) the markers that you have made in your DAW (Variations, Fills, Breaks, etc) and it copy in disc of Audya, in folder USER_AUDIO_DRUMS....
It you can to put in any styles that you want, from Style View....
A diferent way is to searching loops from CD,s and whoever loop if you like, copy also this, in disc of Audya and you can, be put in any styles....
The markers of User_Audio_Drums it will be put from Audya, with automatic way with length of Loop.....Of course if it correct your loops.....
