Hey hey,
I've been trying to (re)discover a delay opcode in Csound that offers to specify the delay time or buffersize in samples. I was sure that there is one opcode that does that. Am I making this up in my head? 
I know that I can easily convert between time in seconds and "time" in samples, but it can be handy to have that.
Best wishes and thanks for any hint,
Jeanette
