[Csnd] Two instances of PrePiano?

Subject[Csnd] Two instances of PrePiano?
With the program below, I was expecting two instances of prepiano to play
simultaneously. Why does it only play the second note? I hoping to play a
chord from the instrument?

Many thanks

Both instances are playing here. It’s hard to hear because they’re the same pitch class, but
if you change it to an interval other than the octave you will hear it

Did you try zar first and zaw the mixed signals? If you use chn istead of the zak system, then you can mix them with chnmix and as a bonus you don't need to initialize them, you can directly call chnset (not sure with chnmix, I tend to read and write for mixing).
