Is it possible to get the drivers to slip on a DCC, sound equipped steam loco and also get a prototypic sound to match? One of my fondest memories is the first time our crew ran the 765 under its own power back in the late 70s. Our crew member let out the throttle and the drivers slipped, with the resulting sound and a cloud of dust. Landing on the moon? There was no comparison!

My first sound install was a Tsunami heavy steam decoder in an N&W Y-3. I was mighty impressed with the sound of that decoder (still am) and I recall having the drivers slip with the accompanying sound.
From Soundtraxx:
When one set of drivers slips, you will hear an extra set of exhaust chuffs. You can simulate this on our steam Tsunami decoders, by using our “slip rate” feature. You can put select an articulated exhaust with a slow, medium, or fast slip rate.
I haven't run that engine in quite a while. I'll have to check the Soundtraxx user manual for the settings for this sound but I'm sure it's in there.

Now my BLI PRR T1s that were known to be slippery engines don't have the effect (that I have found, anyway) in their Paragon II decoder.
Happy modeling, Ed
I'm not sure that it matches up exactly, but it's obvious with the Tsunami when you get wheel slip. This may be because I've gotten the CVs that govern DDE set up in my locos. Obviously, Ed has dealt with articulated sound where this is simulated a somewhat different way there.
Otherwise, to hear wheel slip on a Tsunami or other sound decoder-equipped loco you will need some sort of cam on the axle to sense slip and convert it to the proper sound by supplying this feedback to the decoder.
