Re: [LAD] JACK Graph Internal Latency? (was Re: A small article ...)

the data from the other JACK client isn't available just because you delivered it to its input port. that other client has to actually run its own process() callback. that doesn't happen while yours in running in. to paraphrase your code: int gx_jack_process (jack_nframes_t nframes, void *arg) { get_the_input1_buffer (); get_the_output_buffers (); compute_output_data (); // delivers to outputs get_the_input2_buffer (); } the problem is that the contents of "input2" is just the same at any point during this entire function because the other client has *not* executed its process() callback. what you are reading from input2 is what the other client executed *last* time it executed its process callback().
