The modularEEG with firmware version 2 (
http://openeeg.sourceforge.net/doc/modeeg/firmware/modeeg-p2.c ) supports
only 6 channels, for more channels you need to use firmware version 3 (
http://openeeg.sourceforge.net/doc/modeeg/firmware/modeeg-p3.c ) and modify
the firmware appropriately. But you need to also consider the limitations
of # of ADC supported channels of the atmega controller and probably the
bandwidth required. I am using AtMega16L on my customized EEG-SMT design
and this chip supports up to 8 channels, but right now I am using only the
firmware version 2 for best compatibility.
