Hi,
Like others here, I wonder why Märklin is not doing more efforts to sell the mSD decoders, while they initially did quite a good job. As far as I know, they work well, and I don not think that they are overpriced. However the documentation for the Decoder Tool (mDT, software) is very limited, and indeed I know no documentation about how to make motor sounds (and very little about making any sound in fact).
But... I suspect that the combination mSD (decoder) / mDT (software) / 60801 ('sound programmer') / some access to a CS2 for firmware updates...
... can be more successful than most would expect. I could produce simple sounds, "loop" sounds (whistle), and... a "draft" motor sound.
You can listen to my "draft" motor sound here :
https://vimeo.com/134098534There are good news :
1) you don't need to produce all of the sounds "components" shown on the post by Jonas above. A few sound files can already provide something acceptable, depending on the motor and how demanding you are.
2) I have some understanding of it, still limited but much better than nothing, and using the 60801 is helping - I just discovered that there is "log" file produced when uploading a sound, it gives some hints about how it works. The fact that you can connect a speaker to the 60801 is also very useful, you can test every sound including motor speed up / down.
3) Although the process is quite long at present, the more we understand, the more we can simplify. In particular, I use a small script to copy a few file with simple names (e.g. idle, speedUp1, etc.) to the Märklin names: this may help understanding what needs to be done, and provide other motor sounds with less efforts.
This is a work in progress. It may takes weeks, months or years depending on my time availability... but if someone is interested in sharing knowledge about this, I am more than open to it. Given the time, I would even try tor write a complete manual. If you have suggestions about how and/or on which site to do this efficiently, it is also welcome.
Maybe Märklin could help if they understand that users are interested? Personally I would not buy LokSounds if mSD works, with fine sounds that I can modify. We want to help Märklin staying alive, don't we ?
So no ESU if not needed, and please, Märklin, some help would be welcome ! At least, don't stop providing a minimal support for the mDT software (It may worth an update, after 3 years ?), selling compatible mSD, and selling the 60801. The only thing I would be upset with, is that my efforts become useless because some component becomes unavailable.
Philippe.
