Hi, Csounders!

I suppose that at the beginning the opcode 'pluck' was just some orc+sco,
wasn't
it?

Does anybody know where can I find this (or close to it as much as
possible)
orc+sco?

Also, what is the "two-tap averager" (I found this in
 some article about Karplus-Strong algorithm)?

Thank you.
Regards,

I think you are wrong when you say

I think it was originally coded in C; it certainly is very old and was
already there before I ever used csound

Sounds like an interpolating delay line, using taps at two points and
doing linear interpolation.  Better answer from those who know, or
after a reference
