Hi when I try to run the Steven Cook VCS3 synth found here (csound5 Linux):

http://www.csounds.com/cook/csound/VCS3.orc
http://www.csounds.com/cook/csound/VCS3.sco

    I get these errors shown below. Does anyone have any insight on what might
    have changed with the assignment code to make this illegal?

                   kfreq  = ifreq + afmod + 68.50634

    Or has this always been wrong, and this instrument has never worked?
