I talk about a audio2midi converter, it work nice with the
jack_ringbuffer, and also nice with the direct use from the port_buffer.
I try to figure out with on is best for this purpose, and didn't come to
a result. I think, the ringbuffer must use more CPU and mem, but I can`t
see it realy.
So when I get you right, I have no need to use the ringbuffer here ?

Hi all
I have a question about the useage from the jack_ringbuffer for midi
out_put. I'am unsure to use it or not ? Can someone tell me what is the
advance when I use it, in relation to write direct to the port_buffer ?
they are totally unrelated.
the port buffer is where you read/write data that you wish to
collect/deliver to the rest of the JACK system.
using a ringbuffer is an optional but useful approach when you need to
make the data read/written during the process callback available
to/generated by some other thread.
