number of output channels a grid of size (samples, channels). any number of samples may be given, but the number of channels must be the same as the number of channels specified in the constructor. the signal of outlet number n is made from the column number n of all the grids received, end to end. when there are no more rows to play, the output will be zero. kHz this example shows a weird formula generating a grid of size (16384 2) that is turned into two signals. this has to be big enough so that it doesn't get empty when you are sending grids that are supposed to be connected, else it will cause a kind of dropout, which is not a dropout of the whole pd, just a dropout of [#to~], because [#to~] plays zeroes when it doesn't have anything to play. number of samples (per channel) to keep in advance. this has to be a power of two. default is 16384 (thus it takes 64k per channel. note that GridFlow's own buffers don't take double the RAM when in 64-bit mode, unlike [table])
