Thanks it was done using samples from the real instruments that I then played using a midi keyboard. I used a lever on the keyboard which can bend the pitch and that allowed me to get the sitar notes to sound the way they do. The tabla is a sampled loop.
Peace

Yeah, I was wondering about the pitch bending. The pitch wheel on a midi keyboard is probably really handy for that. I'm planning on getting a midi keyboard soon, gonna use some crypto to pay for it. :-)
