Another question then. Would I be safe in the presumption that the sound unit operates on track power ? It's the analog version.
I believe I just found some answers to my questions. "Shourt Line by Soft Works Ltd.", has a complete instruction manual on their site. One particular instruction indicates that Pulse Width Modulation should not be used as the power supply for the sound unit. G Scale graphics Railboss products use PWM, so that makes my decision easier. Don't buy it.:holdon:

I am finding a fair bit of 'analogue' circuitry does not like PWM divided voltages..
If you use the 'divider' CV's to 'step down' the function outputs on Massoth kit, it is a form of PWM that comes out the function output.
I have had to add small electrolytics, as smoothing, to get some things to work properly.
