Steam sound problem

[ilovenxstage]

I've downloaded a steam locomotive (L&N 152 from the DLS), and added the "Steam Soundz" addon, also from the DLS to it, and although the sounds themselves are good, there are only two chuffs for each revolution of the wheels, instead of the correct four. Other steam engines I have, both default and addon, have the correct number of chuffs. Is there a way I can fix this?

Your keywords "two chuffs" jogged my memory and a search points to this thread:

I hope this of some use, if nothing other than as an explanation of things. Wish I could tell you more.
