Coming back to CSound after a while I notice that for some reason the "randi"
opcode doesn't work anymore as expected. I don't know how to fix this.

Here is the error I get in CSoundQT-d-CS6:
/"using callback interface
error: syntax error, unexpected T_OPCODEB  (token "randi") line 26:
>>>        a4   randi <<<
Unexpected untyped word a4 when expecting a variable
Parsing failed due to invalid input!
WARNING: Stopping on parser failure/"

I didn't find any solution in the forum.

Here is the .csd file coming from the famous Amsterdam Catalog:

Thank you for any help.

I think this is OK in the latest release version of Csound.  It’s OK with the current git develop branch sources (tested now).

Otherwise, the fix is simple

> a4   randi   (iamp/100)*iperc, ifreq

becomes

a4   randi   iperc*(iamp/100), ifreq

Remove the space between randi and the parenthesis.
