[Stk] relationship between rtaudio buffer size and jack buffer size?

[Iain Duncan]

Thanks for the explanation, Gary. Does this mean the buffer size is
equivalent to the csound ksmps number? ie this is the number of samples
computed in one pass of the audio number crunching loop?

thanks so much for the help on a Saturday night. =)
