Hi,
Since a few days I am the happy owner of a 2box. Out of curiosity I tried to understand the format of .dsnd files, and this turned out to be not so difficult, except for a few details that I still don't understand.
As a proof of concept I sampled a clave, and tried if I could download it to the 2box. It worked

! You can download it from

Note that the quality of the clave sound is not good. I don't have a good mike and, more importantly, somehow my computer generates noise that influences the recording.
I also did an experiment to copy a VST snare, because being able to use VST sounds in the 2box was my main goal (even though the sounds that are already in the 2box are really good!). It worked, but more experimenting is needed to get good volumes for the different layers.
Happy drumming,
