Hi all
As you can probably tell from this title and description, I am new to posting on this forum, well actually new to posting on any forum!. So I'm not sure how to start. If I perhaps explain what my current set up is and what I want to do and then hopefully somebody will be able to point me in the right direction. The current set up is moderately large OO gauge layout comprising of about 25ft of track, some DCC Concepts Digital IP point motors, and about 20 'steam' locos. We have a programming track and use a NCE powercab to program various addresses and CVs. The main track, points,signals and engines are controlled through a Raspberry Pi and Gertbot board, using the open source software available with the Gertbots, which I have modified to accommodate the various engines, signals and points, each is assigned an address, two for signals and points. I want to now move on to sound. As I understand it the original motion decoders need to be replaced by one capable of sound as well as motion. For motion I address the short address given by the powercab to each engine. This is my question:- Can individual sounds e.g. shunting, whistle etc be addressed independently, or are they built in to the speed at which the engine operates?
I'm sorry if this is basic stuff but I just cant get my head around it at the moment and could do with some guidance.
