Hi everyone,
I started to use motosynth plugin to simulate the engine sound of a vehicle.
There’s no documentation on it but after few days of trials and errors I figured out how to use it (at least enough for my purpose).
To use this plugin, I need to create and set up “Moto Synth Source” assets but I haven’t figured out how to create a new one.
The only asset available in the list is Moto Synth Preset (\sound\synthesis).
So the only way I found out to create a new one is to copy one from City Sample Project and then to modify it and duplicate it everytime I need a new one.
Any idea about how to find it or add it to the list of the assets ?
Thanks.

dang bro nice stuff
i figured it out by the way!
right click your preferred audio file and there is an option
now what im trying to figure out is how to use audio motor synth
Thank you!
Regarding the use of motosynth, they used it in “city sample” for the vehicles.
It took me some time to understand the blueprint, but then I’ve been able to use it in my project.
yea i get that it seems as like it doesnt work inside my project there is no sound coming out of a sample
maybe lets exchange or discords so we can stay in contact about this? mine is Drizzyyy#5526
Same here, still it works fine on city sample. I looked evrywhere but couldn’t figure out why.
I found a workaround:
I created a 5 second wav file with no audio that I set in loop.
First, I play the dumb wav file and while it keeps playing I can play the “play tone match” in the motosynth source or the “start engine preview” in the motosynth preset.
But when I play the project in the viewport, everything works fine.
Hey mate still you should hit me up, i want to know how it sounds for you i made my sound with metasounds and it sounds like this:
i want to know which solution is the better one.
it took me a week to come up with that mate, so i wonder how you did set up yours.
Greetings drizzyyy
A colleague of mine and I recently came across this issue and I believe we may have found a solution. It seems that the problem comes from the Submix not detecting the Motosynth as active and playing. To fix this, make sure that the Auto Disable option in the respective submix you are using is unticked and this should sort it out:
ty that fixes the not hearing part. still dont know how to set it up tho 
Could anyone explain how they got it working?
Years later, I still see no information on it. (Just this thread.)
I try using files from City Sample in a plain Chaos Vehicle project and it makes no sound.
Turning off Auto Disable as mentioned above does make Play Tone Match audible. Seems like a temporary fix to help understand what the real problem is, and maybe find another way to resolve it.
But also, in game it still makes no sound.
With MotoSynth component in my vehicle actor, I do cmpt->Start on Begin Play. I’ve tried different values and methods of setting RPM and Volume Modifier. But no sound. Missing something I guess? Maybe someone knows? That’s all I saw in City Sample.
Found using Moto_Sport_Preset produces no sound, while the other presets produce white noise. But no engine sound.
Found cleaning up the AudioController cmpt from City Sample and using that, well somehow that plays. Even without any submix changes. I don’t think it has other RPM sounds. Not sure what that does different to make Motosynth work.
