gunrunnerjohn: Sorry about the jumpiness. I started that thing with good intentions, then remembered how much I hate video editing and ended up just posting the screen recording as-is 
Moonman: Yes, it will do Bluetooth, RF, Infrared and WIFI using Arduino shields. I don't have any Lionel Legacy, but it is on the list.
AmeenTrainGuy: Thank you for the offer. I need help with styling. Still working on basic architecture for now. It's PHP and powershell. Just starting to move as much as possible to c++.
eddiem: MIDI goes to PC. PC goes to devices that can control the higher voltages (e.g. TIU, Digitrax command station, relays connected to Arduino).
Ted S: That has never occurred to me, but makes sense. I will add a random generator with parameters to the logic setup page. Thanks! More code
EscapeRocks: Yes. I almost bought a Behringer too. Any should work. The AKAI APC40 is the bargain, IMO. Under 100.00 on Ebay and built like a tank.
