Did you try specifying ksmps but omitting to specify kr in the orchestra?

John,

Here is the actual error message generated (sorry I didn't quote it
correctly earlier):

orch compiler:
25 lines read
sr = 48000.000000, kr = 480.000000, ksmps = 100.000000
error:  inconsistent sr, kr, ksmps
1 syntax errors in orchestra.  compilation invalid
inactive allocs returned to freespace
end of score.              overall amps:      0.0
           overall samples out of range:        0
0 errors in performance

This is using the same test .csd I sent earlier; it does *not* specify kr
(csound calculates it itself).

I will methodically go back and find the latest GBS that does *not*
demonstrate this error, and report back to you.
