But the page did say something about "coaxial cable"... I am "assuming" they plan on controlling this via Ethernet... At least that's how I would do it...
I have fought, and occasionally win, battles with RF compatibility... Probably one of the best arguments around for building "all-mechanical" pipe organs, ones that use electricity only for wind and
illuminating the music rack... Even at that I know of a Paul Fritts church organ which has provisions for
winding the instrument "the old-fashioned" way... Thus a power outage wouldn't interrupt the music!
Moreover one would only have to worry about fire damage from a lightning strike... Elsewhere on this forum I linked to an organbuilder's website on which is an excellent explanation for why with electric action instruments lightning protection of the power supply and proper shielding of the circuits which connect the console with the pipework is essential to the instrument's survival...
If you think a "toaster" is immune, think again-- Speaker wiring makes for an excellent antenna and audio amplifiers make wonderful "unintentional radio receivers" when presented with a sufficient density of RF energy. Personal experience with insufficiently shielded and "earthed" equipment reveals that it doesn't take much at all to accomplish some interesting, but largely unwanted additions to your program material
Additionally-- there are (by several orders of magnitude) a far greater number of semiconductor junctions which fail nicely when presented with thousands of volts of electrons flying about trying to "find ground"
The other consideration is the radiation of the control signals from such an organ into its immediate surroundings which may make the operation of wireless microphones used by other musical performers and vocalists problematic... One hopes the engineers involved in this project take all this into consideration
Maybe this is an example of a case where one should forgive "security" for "freedom"
