number of channels (default: 1) signal in inlet number N will be column number N in the output grid. a grid of size (blocksize, channels) where blocksize is the current blocksize as defined by the [block~] currently active in this context. (default blocksize is 64) Turn several signals into a sequence of multichannel grids. capacity of the buffer. this either 0 or a power of two. (default: 0) when it's zero, the number of samples per grid (for each channel) is the current blocksize of the canvas. when it's nonzero, the number of samples can be higher (a power of two multiple). but don't make this number less than the canvas' blocksize !)
