There's no on board sampling or sequencing just a box with pads that you put an SD card into. That SD card needs to have the samples named correctly and in the right format. I had to batch convert a bunch of samples in order to use them. I was excited to use samples with my other grooveboxes but sadly this didn't work all that well. sometimes the samples would trigger but mostly they didn't. Perhaps it could have been the hardware I was using? Anyway, if you want to trigger samples that you prepared on your computer on a box that is not your computer with some nice drum pads... this will do that. Just don't expect too much more than that.
It is what it is. The features (or lack of them) explain the low price. Of the on-board sounds, maybe three are usable. The rest sound like a toy keyboard from the '70's. The supplied kits of sounds would be funny if not for the reality that nothing you do with this will sound decent.
