> to print out some information at orchestra start, 

Another suggestion / wish:
Couldn't this be implemented as a printks i-time call?
It may be useful to change that opcode to run also at i-time.
Hopefully this means just repacking the arguments into 
whatever struct printks uses and calling its k-rate function. 

The resulting opcode might be called just "prints" - this
would be consistent with current naming of related ugens.
Like
    prints "txtstring", ival1, ival2, ival3, ival4

(The printks argument "itime" would be set to zero, and 
the i-rate arguments are passed to the "kval":s). 

I haven't looked at this, so it's entirely up to you if
you want to check up on it - just a suggestion.

Regards,
