If you play a lot of Celtic music, the Celtic board by V3 Sound is excellent. If you don't need their arranger module, they can put the board in a box and use it as an external module. You can listen to all the Celtic instrument and percussion sounds here. BTW, do you know the name of the 1st song V3 Bodhran Slow Waltz?
