I have a processing chain that starts with 1 x 32 @ 48Khz audio data and ends with 1 x 1 @ 10Hz. There is a rebuffer in chain that causes all subsequent modules to be annotated with 1/150 which I understand to be the clock divider ( my rebuffer is 4800 samples ). Clock rate shift from "1" ( 32 samples per block ) to "1/150" ( 4800 samples per block ). In the example posted the error complains that I am mixing clock rates. I want to use my 1 x 1 @ 10Hz (1/150th) control data to alter a scaler block acting on 1 x 32 @ 48Khz blocks ( 1/1 ). The only way I can achieve this is to use Get param to extract the value output from my processing chain ( 1/150th clockdiv ) and deliver this to the next stage ( 1/1th clockdiv). This works, but why can't I connect directly instead of having to Get Param ?
