How can 960 sites share 384 channels, and who decides which ones are read?

Each site has its own CMOS switch, a single transistor that costs almost nothing; each channel has an amplifier, filters and a share of a converter, which cost area and power. Before recording, software sends a configuration (in SpikeGLX the IMRO table) that connects channel iii to site iii, i+384i + 384i+384 or i+768i + 768i+768, one bank each. The switches hold that choice; nothing scans while recording, so the experimenter picks which stretch of the shank to listen to. The rule behind it: replicate what is cheap, share what is expensive.
