Someone alerted on the LokSound yahoo user group that a next version of the FEF3 will include LokSound decoder (and LEDs). The website info shows an announcement of Nov 2016 and “due late October”, which I take to mean 2017. The info states that sounds of the 844 were recorded Oct 2016.

I have a Genesis 844 from around 2013, with Tsunami sound and, I think, LED lights. I do not see the sound file shown as available yet, but presume it will become available for the Select as other “manufacturer” files. I’ll be excited to revamp to a Select with improved motor control and while at it will add a capacitor. My grandson (and I) will get a kick out of knowing that the sounds are the actual 844, as we chased it twice here in Texas.
