Add some momentum, CV3. See what that does. This is why I dislike Tsunami diesel decoders, they have this same fault, and adding momentum does not fix it. QSI and Loksound, just add some momentum, then crank the throttle open and you get the rev before the loco moves, then turn back to a normal speed before the loco actually gets going at the high speed. Should you be doing a light engine move, just gradually open the throttle and the loco will move out without the heavy rev. It’s easy to simulate both starting a heavy train and doing the light engine moves without having to resort to manual notching - although that is another method, since then the prime mover is operated independently of the loco itself.
To add enough momentum to get the sound coordinated would be a bit absurd for a switcher. If that were required, why is the factory default (which I am using) so low (5/255), anyway? And a light engine move still should have some rev at the start. Sorry, Randy, what you suggest is not a solution, certainly not for a yard switcher. The Paragon designers need to go back to the drawing board.
I’m the OP of this thread and I’m tickled pink with the sound functions of my EMD NW2. You didn’t mention contacting BLI support and if you did what was their response?
Yes I contacted BLI support and their response was not satisfactory to me. The person who responded (by email) didn’t seem to appreciate what I was talking about, and suggested some CV changes which did not affect the problem at all. They finally said I could send it in (shipping at my expense), but since my friend’s Paragon2 does the same thing, I have no hope that anything could be done short of redesigning the Paragon 2 decoder architecture. Unless ours are the only 2 that have this problem. Apparently the earlier release did NOT have this feature.
If you (the OP) are “tickled pink” with this disjointed sound decoder, I’m happy for you. Not everyone may care about this unrealistic sound match. Fine.
First, we are not discussing selection of a decoder - This locomotive only comes with one already.
Second, according to my one diesel Tsunami, I agree with Randy (rrinker) that the Tsunami has a similar fault (if you will)( but not as bad in my view). But I have an older BLI switcher with QSI sound and the synchronization of sound and speed is good. More than that I cannot say: I don’t have a Loksound diesel or any other (MRC, Digitraxx, etc.) to compare. Nor can I comment on the new QSI Titan for diesel.
Have you tried it? You don;t need so much momentum that you can;t control the thing - plus the decelration is independent so you can still stop quickly. They key is that with some leel of momentum plugged in, you get complete control over having the prime mover rev up or not. And for how much. FOr a road unit, you can use a large rmometum value and hevthe thing chug while grinding along at a low speed for a significant amount of time, OR you can simple adjust the throttle and immediately reduce the loading after an initial burst yet continue to acelerate. That’s what makes this a useful feature on those decoders that support it - try it on a Paragon 2 and see if they too support it.
How else do you propose handlign this? The difference in load on level track between no cars and 5-10 cars is so neglible that trying to sue BEMF to automatically do this is nearly impossible. On grades it can work - they new TCS WowSound secoders do it to make labored chuffs going uphill and quite them down and add rod clank going down.
Easy there big fella’… I sure wasn’t trying to rattle your chain. All I did was express my like for the EMD NW2 and simply ask (contacting BLI support) what you didn’t mention in your initial post.
I have two sound locomotives, both from BLI and I am really happy with them. I got the last one four weeks ago, a NW2 switcher. It is weel detailed, have an excellent slow speed right of the box and, at least for me, the sound is amazing.
As a side note, anyone who has a Paragon 2 or stealth BLI steamer, and decides he wishes to use a Tsunami, will discover that the installed chuff sensor will not work with the TSU. Reason: a reed switch pickup is located next to the flywheel, which contains one magnet. The number of output pulses per driver revolution is the same as the gear ratio, which, for example, is 24 in the NYC Dreyfuss. The Paragon 2 must have something like an input counter that divides by six. I’m hoping to come up with a simple one-chip counter so the TSU will see four pulses/rev.
