Back about 12 years ago I had a rush of blood to the head and bought a British outline loco..an Aristo Class 66 fitted with an ESU Loksound V3.1 decoder.
It had been professionally weathered and set up by South West Digital.
I think that the sound file and control set-up was commissioned by them from ESU.
The sound file that is now available from ESU is more or less the same as the one commissioned by SWD.
The board file has been set up so that it controls the lights (start-up, running and shutdown).
I also, somewhere, have an unused Phoenix PB9 with their ESU sounds on board.
The ESU is absolutely stunning in its operation and the start-up procedure is a wonder to listen to, and I have a good selection of diesels (all US) using ESU or Phoenix sound boards to compare it with. The Phoenix version of the sounds is also very good but the ESU does swing it.
I might be parting with the Aristo 66 in the future if anyone would be interested
