Hi Mike,

yes there is a way to change it

open the .tmd file with a normal editor and look for

...
Sound0File = "Klemm1" soundfile 1
Sound1File = "Klemm2" soundfile 2
Sound2File = "" soundfile 3
Sound0RPM = 2850 frequency of Soundfile 1
Sound1RPM = 7300 frequency of Soundfile 2
Sound2RPM = 13000 frequency of Soundfile 3
Sound01RPM = 2180 soundfile 1 to 2 change rpm
Sound12RPM = 12500 soundfile 2 to 3 change rpm
cd ../

this lines setup the sound

Change it like you want or replace complete
