Hi guys, it's me... Again... BigGrin

So I tried googling for this, but again, can't find english resources. Also can't google in german (yet).

So I've had my first experiences with mDT today. I've managed to add prototype sounds of BR50 to one of the decoders. Got the braking sounds to work also. I'm very happy!

Then wanted to install an steam mSD3 (60975) to a V200 diesel. Found to correct sounds and set the loco type to diesel in mDT. However even that I have set "Sound without Output" to have a braking sound, the loco does not make the sound when doing hard brake. Any tips on where I should look at (I got this to work with another loco)?

Then another question about the calibration. I have MS2 so can not initiate calibration in MFX mode. So I turned MS2 to DCC only, wrote 77 to CV7 and got a few locos calibrated with DCC. Here's the questions though. Does the calibration sustain when switching back to MFX... I think it does, but not really sure? Also what happens to calibrated decoders when I take them back to the Decoder Programmer USB stick, and save new settings from mDT, does the motor settings get overwriten with what ever settings I have in the mDT project or does the calibrated setting remain?

Also, there has been references in other threads on configuring the smoke unit to have some sort of setting, that makes it smoke less when loco is running in lower speeds and more when higher speeds. Where exactly can this be controlled in mDT? I'm looking to install smoke units to metal body diesels, but wan't them to smoke only a little.

Bear with me guys, I really appreciate it.

BR,
-Eino

1. braking sound : no idea, didn't play with it, relying on some base project that had them already. Seems there can only be one "Sound without Output" sound of type "Bremsen" in a project, dragging another one will override the existing slot if I try. So maybe there's some internal magic about choosing a sound from that category?

2. calibration : is remembered across protocols. Load the project that you have for that loco and then read back the decoder values, after you have calibrated it on the track. That way when you flush all settings back to the decoder the motor parameters will be the same, otherwise they will reset back to project defaults. I usually run the calibration + change sound volume, light intensity and such and when I'm happy with how it runs I update the project file so I don't risk loosing them.

3. if the smoke unit is attached to an AUX output, and declared to be a smoke unit output, it will act as you describe. Please see below my settings for one.

Thanks for the reply!

For some reason or another, brake sound volume was 0. It's now working when I set it to 100.

Good to know info about the calibration. So is the read back performed on the most top level main menu or is there a button for it when a project is already open?

So I guess the dimmer value (255 in your picture) controls the intensity of the smoke too, not just lights?

I don't mind doing lot of testing, but I'm sure the decoder will eventualy break if constantly being removed from the NEM board. Blink

Thanks!

Can I ask how this dimmer works, is it reducing the voltage or is it pulsing the output from say 16V?

@Eino: load the project and then from the main menu : Decoder -> Read out decoder

You don't have to remove it to fine tune settings. All of these parameters can be adjusted live with CVs, either in POM or Programming track modes. That allows you to change the running parameters without removing the decoder.

The decoder manual is thin on this topic, but one can find every tunable bit in JMRI or in the german-only sheet of information here.

For this area my settings are (as also seen below):

Aux 1 mode = CV120, bits 0-4, current value = "Smoke generator" = 7
Aux 1 dimmer = CV121, current value = 255
Aux 1 period = CV122, current value = 20
Aux 1 delay = CV123, current value = 0

So write a different value to CV 121 to lower the smoke intensity. The value is instantly applied and stored permanently in the decoder, unless you reset it to defaults (write the value "8" at CV 8) or you flush the project back to the decoder.

@mrunix: it's always PWM with these decoders, a value lower than 255 is translated in proportional time pause. The voltage is not regulated, so don't count on it being exactly 16V. More like 18V in my case.

Thanks! Ah, ofcourse from the menu.

I’m on MS2 so can’t access all those settings unfortunately.

Edit: except with DCC of course, but it will anyways be pain with MS2.

You can write with MS2 any value in any CV, no problem.

As costing wrote, I also usually read back the decoder after a calibration. but the after that I normally leave the decoder in the locomotive and program any small changes through the CS3 or with it.
Note that some setting changes actually require full reprogramming with sound, and that takes a long time with a cs3. and note that it's not possible to change those settings on the cs3 or with CV's etc. Examples of such settings are the sound levels of Normlast, Leerfall and Grundrauschen etc. (Grundrauschen is only available in later decoder projects defined as Soundfile Version 2).

Hi all

Can I ask what calibration means?

Great info on this topic.

I'm starting to build a holistic view of how this "ecosystem" is suposed to be used. It of course brings new questions, but the first one is this: There's an menu item to download projects from Märklin server. The directory structure is not exactly self explaining. Is there an index anywhere where I could seek projects by the loco name?

Unfortunately not, the best way is to use the Marklin/trix/LGB online product database and get the numbers there. eg M39 contains all released projects on Marklin 39xxx series locomotives etc. note also the subfolders under M60-L55 and W0 folder. And note that you can open decoder projects with eg 7zip and extract the sounds you want etc

il try as best as I can to give a short description......
it means that the decoder performs a self-calibration of the motor, and adjusts the settings for the best performance. in most cases, it improves the driving characteristics/ performanse... and the motor type must be set before calibration. (note that there is currently a software bug in the CS3 affecting this when the system language is set to English). Sometimes you can try several motor type settings and use the one that gives the best result.
It's a bit extra recommended on bell anchor motors. (glockenankermotor).
ref the MSD3/mld3 manuals for instructions.

You need to know the catalogue number of a loco with a suitable sound file. The file names are the catalogue number prefixed with M for Marklin, T for Trix and L for LGB.

The sounds in the general sound catalogue that can also be downloaded are in sections according to sound type.

Well things actually went from not so clear to very clear after this.

These work great, even thou there are all sort of logical operations etc, I don't quite understand what they are supposed to do.

However, on these Märklin sound projects, there are quite a lot of functions mapped. Are these supposed to work with the mSD3 decoders? When I program the decoder only 16 functions go to the decoder. I read the manual, but did not notice any reference to number of available functions (except the function tables for the preloaded sounds)?

Also, has anyone ever figured out a way to edit the sound files? In my opinion the diesel running sounds are quite high pitched and I'd like to do some audio equalisation on those. Cut the high end down a bit. The .wav files inside the project file obviously are encoded to give some copy protection.

Thanks!
