You could introduce bluestone dust as a 64 power level version of redstone. Redstone dust could then be used to create the digital red alloy wire and bluestone dust could be used to create the analogue blue alloy wire. You might even want what is currently Nikolite to become bluestone dust. (This would make Nikolite useful in-world!)

The two dusts could even be interconnected but any bluestone dust signal greater than 16 would be maxed at 16 when converted to redstone.

You could also include a bluestone torch which has a signal level of 64 and even bluestone repeaters and comparators!

This could also fit with the re-skinning of the logic circuits blue, have them able to perform analogue calculations with a maximum of 64. If redstone gets connected to a gate's output that is greater than 16 then have it max out the redstone dust level at 16.

I'm going to close this issue, not because it's bad but because a lot of this is already in our roadmap. Hopefully you will like what we have in store :)

If I'm nkt misstaken, but I've yet to look into something like that, a signal strength of 64 would not be possible. Something with the max values being 16. Don't get me on that one , that's purely if I remember correctly.
What /is/ possible is instead of having the signal strength decrease by one each block it could decrease by 1 every 4 blocks.

Again. Purely memory ^.^'
