Hi, I have been trying to run Steven Cook's VCS3 emulation found here: http://www.csounds.com/cook/csound/VCS3.orc http://www.csounds.com/cook/csound/VCS3.sco I am using Csound 5 on linux. When I run the code I get the error message listed below. The offending line which occurs twice is: kfreq = ifreq + afmod + 68.50634 This code is from 2001. What has changed since then to make this illegal? What might be a suitable workaround to allow this code to run on csound 5? Thanks - schwaahed Error: orch compiler: 303 lines read instr 1 instr 2 error: input arg 'ifreq+afmod+68.50634' of type a not allowed when expecting k, line 61: kfreq = ifreq + afmod + 68.50634 instr 3 error: input arg 'ifreq+afmod+68.50634' of type a not allowed when expecting k, line 87: kfreq = ifreq + afmod + 68.50634 instr 4 instr 5 instr 6 instr 7 instr 8 instr 9 instr 10 instr 98 instr 99 2 syntax errors in orchestra. compilation invalid
