The most frequently used asian woodwinds on the BSG score were:
Membrane Flute (chinese, often called a dizi)
On very rare occasions towards the end of Season 4, I used shakuhachi. But, in general I avoided it because so many scores in the 90's used Shakuhachi I got totally sick of the sound. It took me a decade to warm up to the idea of using it again.
But, yeah, that was the bansuri in the RAZOR MT for sure. Hope that helps.
