G'day guys. Ain't heard from me for a while, but I'm still kickin'. 
Got some questions on Loksound, if anyone can help.
I've got 2 Loksound V 3.5 decoders turning up via phone order next week. I've down loaded the manuals, and have read up on them. It's the back EMF load control functions I've got questions on. I understand what back EMF is, understand the values to be set in the CVs and what they should be. But I can't find anywhere on how the decoder processes the back EMF info, in relation to the values in the CV, and what it does to the power supply to the motor.
The back EMF voltage CV is set to what the back EMF voltage is, when at top speed step, and the motor is not under load. (or something similar to that). I would assume the decoder then caclulates what the back EMF should be, at the selected speedstep, if the motor was not under load. If the motor is under load, the revs would be less, the back EMF would be less, therefore the decoder will automatically increase power to the motor, until the back EMF voltage is what it is supposed to be at that speed step. Am I getting close? This would ensure consistent motor revs at the selected speed step, no matter what the load on the loco is. This, of course, works in reverse when going downhill with a heavy load. The back EMF would be HIGHER than expected, so the decoder would automatically REDUCE the power to the motor until it measures the expected back EMF voltage. Am I getting even closer? The other CVs associated with load control would affect the rate at which the decode increases/decrease the power in such circumstances, to compensate for flywheel inertia etc, and also up to what speed step the load control feature is utilised. Am I even closer now, or am I way off the mark?
I currently use NCE basic decoders, with the torque compensation feature (which is excellent, by the way), and I fully understand how that works.
Hope someone can help me with this.

. if NOT, then you will need the LokSound programmer, and it will set it up for you:thumb:.
