LEGO synthesis

Modular science/art machine that is designed to be a hands-on teaching-aid for demonstrating anything from electrical wiring to sonic wave-form moulding, music theory and pitch control, with keyboard. It could possibly even serve user with singing-lesson potential. Yes, perhaps I am packing too many ideas into one here. Consider this more of a brain storm that could be refined rather than anything near a finished product. I have so many ideas for LEGO that I just thought it was about time that I submit something. Principals of wiring/circuitry (low voltage) could be taught by providing layover schematics and/or simply by printing numbers, lines etc on base-plate with underlying connections embedded. Different circuits could be set up and demonstrated through the incorporation of leds, diodes, transformers? etc. A voice could help read through instructions and later when prompted to test, could indicate success, “short”, “open” etc and would then help teach principals. The music module could have a self-wired keyboard with analog/digital keyboard effects and perhaps even more add on possibilities just like true synths. This could be a true synth, in fact. Kids (and adults) would love a vocoder. The built in mic would allow for speaking, distorting or just pure singing. With singing, the machine could give helpful tips on whether a singer was sharp or flat and tell them the note that they were singing. Keyboard could light up corresponding key which could be played to have a properly tuned version of this note. Criticism could be turned on or off and effects could be added to allow user to simply sing and feel good regardless of skill level. I see all surfaces as having usable LEGO texture. This would allow for customization of all services (top anyway) with possibilities of smooth or textured, clear or opaque panels, blocks etc. Electrical connections could be made with LEGO blocks, probably 2x2 bricks I see touch pads: 4x4 flat clear panels with multiple colours...
