DCC Sound for MM 121 class

[Noel]

I've had so much fun driving these locos with DCC sound. I purchased MM ESU LokSound decoders and also ESU LokSound decoders from one of the specialist sound decoder suppliers. 

Both sound good, but the MM decoder seems a little basic, lacking ESU's new 'Full Throttle' driving functions and seems to have no independent DCC operation of the head lamps separately from the running lights. Quite good but just not as sophisticated nor comprehensive as the specialist sound projects. The WheelTappers project in the video below seems more advanced making full use of the new LokSound V5 'Full Throttle' driving features that facilitates prototypical  driving, coasting, acceleration of light, medium and heavy train loads, in addition to coasting and prototypical braking distances, also with a 'throttle hold' feature that allows manual control of notching while loco speed is remains constant. Not flaming the MM chip, but generic manufacturer sound projects rarely have the comprehensive sound and driving features that specialist sound providers such as WheelTappers, MrSoundGuy or Leggomanbiffo are used to producing for connoisseur modellers. Out of the box the MM ESU decoder sounds good, just not as prototypical to drive as the specialist projects suppliers. Pricing seems similar. No connection with WheelTappers, just a happy customer.

Noel,

Very interesting video. Just wondering how you got the magnet to uncouple the kandee .  I'm confused as it looks to me that the magnet would pull down instead of sideways. Maybe you could post how you did it.

The Kadee magnet is designed to pull the pins on the couplers to the side rather than down.

My understanding of how it works is that the magnet induces magnetism in the (presumably soft iron) parts of the couplers. The couplers will both be of the same pole, as their magnetism is induced from the same source, and, thus, they will repel each other. They can each only swing to one side - and, as they are necessarily facing each other, this means that they will swing in opposite directions, away from each other, thus uncoupling.

Nice video and setup Noel.
