Hi,

I'm having some trouble in understanding what I'm
seeing in  my experimentation.  I hope someone can
clear it up.

I got Joachim's 'OnDtct.csd' to work nicely by substituting
an event statement for the 'schedulek', but I thought this
would be a good place to try a UDO (which I haven't played
with much) to implement the schedulek.

So I added this UDO:

opcode schedulek, 0, Skk
        Sname, istart, idur xin
        schedule Sname, istart, idur
endop

and called it with a slightly modified:

   schedulek "Play",0,1/10

However, "Play" only gets invoked once at the very beginning
of execution.  (I originally had "Sii" for the parameters, but I
thought that mght be causing the opcode to be i-time only.)

I assume, though I can't find it stated, that 'schedule' is an
i-time only opcode -- hence the need for 'schedulek' -- but
I thought that if I put it in an opcode it would get invoked
appropriately.

Where am I going wrong?

Thanks,

I guess I'm misuderstanding the point of a UDO.  I thought it was
essentially an instrument of its own, with an i-segment each time
it was invoked.  This is not so?

Thanks everybody for the illumination!

So I changed the UDO to:

opcode schedulek, 0, Skk
 Sname, istart, idur xin
  redo:
 reinit redo
 schedule Sname, istart, idur
 rireturn
endop

and it worked as I'd initially expected.

Not quite sure abot the 'rireturn'.  If I'd left it out
would the calling instrument also have entered
an init pass?

Thanks,
