How is the Cambodian Tro-U played? (It is a Cambodian lute, with two strings and a bow between them.)?

Question

I have bought a Cambodian Tro (lute) - it is the two-string version where the bow resides between the two strings. Can someone explain in a bit more detail how this instrument is played? Where are the hands positioned? Which strings are played as the bow moved back and forth between them? Does one string cover the treble and the other the bass? Do you apply pressure with the left hand alternately between the two different strings, or is the pressure applied to both strings at the same time?

Answer 1

All I could find was this:
The Tro U and Tro So originally came from China and are very The bow passes between the strings on the two-stringed versions. The player presses down on one string to get the high notes and pulls up, using the "underside" of the bow, to play the low notes. The strings were once made of silk but these days they are made of metal.
