caldreamer so the sound effects are not relavent at his time
caldreamerAir and independent braking can be accomplished using the throttle to simulate the amount of air and/or independent braking is being applied.
are there separate function keys for dynamic and other braking?

Hello All,
In the National Model Railroad Association (NMRA) magazine, November 2022 issue; pg. 46-51, there is a review of the Soundtraxx Blunami decoder and the accompanying app.
On pages 50-51 it mentions Dynamic Digital Exhaust for both steam and diesel.
This is a function of the decoder and not the DCC system.
The article talks about how to set up this function. It involves CVs 32, 503, 504, and 512, along with the "usual suspects" of CV 3 & 4.
This function is available on the TSU-2200 at the MSRP of $132.95, along with other decoders in the TSU series.
I didn't find any other decoder manufacturers that offer what you are looking for.
Hope this helps.

DDE and other types of "load detection" are simply a feedback function of the BEMF signal from the motor that is then used to tell the decoder's sound function to increase or decrease the sound of the "working" locomotive. It is not related to momentum nor dynamic brakes. DDE is also used to increase the "chuff" intensity where dynamic brakes wouldn't have any relationship to steam.
The OP mentions he likes TCS decoders so here is one of their explanations of the use.
I haven't messed with dynamics on any of my decoders as it is not a function I feel is that important to me. Most of the eastern roads I model don't even use dynamic brakes especially in the first-generation diesels I mostly have. Additionally I don't want to devote too many various function buttons to braking. Decoder manufacturers seem to be getting bogged down with independent, automatic and dynamic brake functions crowding an already busy function list.
It seems to me this thread is getting muddied by mention of several unrelated decoder functions.
Dynamic brakes can be fun and add another dimension to operating but it does require operator attention.
ESU has their version of dynamics and here is a look at the Tsunami2 dynamic brake setup.
Good Luck, Ed

gmpullman thanks for the info on Train Control Systems (TCS) and ESU and their versions!

According to Soundtraxx, once setup, this sound function happens automatically because the setup process defines the parameters of CV 32, 503, 504, and 512, along with the "usual suspects" of CV 3 & 4.
As far as speed control, yes, the engineer has to monitor this, just like in prototypical situations.
But, the sound functions are "automatic."
caldreamerI do not use sound decoders, so the sound effects are not relavent at his time. Maybe in the future I will get a sound decoder.
OK...
gmpullmanIt seems to me this thread is getting muddied by mention of several unrelated decoder functions.
The OP has focused on CVs...
caldreamerThe CV's for acceleration and deceleration are: CV 3 (0) The rate of Acceleration CV 4 (0) The rate of Deceleration CV 23 (0) Rate of Acceleration added to CV3 when in an Advanced Consist CV 24 (0) Rate of Deceleration added to CV4 when in an Advanced Consist
These CVs seem to have no relationship to Dynamic Digital Exhaust, but the OP and other contributors to this thread have focused on these.
