The four Play buttons across the bottom are capable of triggering the drum and percussion sounds, the sounds themselves only produce a click, are opposite the 'perc' and 'drum' setting, and in one case you get two different drum sounds from one tap. There are a couple toms that sound right, but even then they trigger on the 'Perc' setting and not the 'Drum' bank.

For this reason I'm selling this as non-functioning, someone knowledgeable will get a good deal from this unit to either re-sell it at 2-3x the price or keep it for their studio. Could be as simple as swapping the ROM sounds or some TLC but I just don't know enough and don't have time to get deep with it.
