My E11/E42 has compressor sound, since it is not possible to play it only while standing only (no trigger), it just plays every minute.
Good... so, every minute it plays the .wav sound you configured in the config file? I mean, I could realize a 10 seconds compressor sound that will trigger every minute. So you ear the compressor for 10 second and no sound for 50 seconds. Can it work?
I remember there was a locomotive playing the compressor but the sound last only few seconds. Is there a limit even on that?
