I've been following your progress with interest. The part I've kind of figured out is this.
I'm going to have a play with configuring the VSD files, including looking at which function buttons (is that the same as "notches" ?) each sound is allocated to. Is there any JMRI or other standard specs for what particular function applies to a particular button ?
In the VSD files you can see the function mapping.
<trigger name="HORN_START" type="BOOLEAN">
<event-name>F2</event-name>
<target-name>WHISTLE</target-name>
<match>true</match>
<action>LOOP</action>
? ? ? </trigger>
F2 is a whistle.?
What I can't figure out is the sound stop and start! If I'm controlling from Engine Driver on my Android the engine keeps playing until I open VSD and stop it.
