Interesting topic as I just spent several hours programming a heavy steam 
Tsunami installed in an Allegheny boiler last night.  I’ve ben using a SPROG II 
programmer that makes nearly instantaneous changes to cv’s possible. That is, 
it permits endless “tweaking” which turns into endless hours, etc.. 
Ed makes a good point. The simulated articulated loco logic in the Tsunami is 
good enough that you can program in slip at three speed levels. I have not yet 
figured out to make the sounds synch perfectly though while using articulated 8 
chuffs per revolution – don’t think there is an electronic solution.  
Oh and this loco has cam wipers installed as well. Of course the cams will 
permit occasional synching but they present their own issues of “random events” 
and “not so good” back up sounds until a decent speed is reached.  On balance 
the synthesizer wins this round and cams are disabled for now. 
There is a more fundamental problem being worked on. The exhaust chuff seems 
much too well defined for what I imagine the Allegheny really sounded like. 
More endless tweaking with the equalizer and reverb cv’s may or may not solve 
this – we’ll see. Meantime saw on the C&O group that someone is planning to 
make an Alleghany sound unit from actual sound tapes. Hmm................
BTW “those in the know” say the 2-6-6-2 being a compound steam distribution 
only needs to be programmed as a conventional loco with some reverb maybe. 
Reason is the low pressure steam emission was overwhelmed by the high pressure.
