The 67 project was coming along nicely and it was time to start getting the sound vs speed relationship how I wanted it. I fired in some settings based on previous experience and ran the loco round and it was clear all was not well. Before I got to halfway on the throttle the sound had already worked its way up through every notch to full tilt! After studying the flowchart it dawned on me what had happened; the most recent software upgrade from ESU had corrected a discrepancy that has existed in the Lokprogrammer v4 software from day one. All I had to do was double some of my numbers and problem solved - for the 67 at least. I then had to go back to every other project I've updated to v4 standards (20+), change all the numbers and test each one again. Needless to say this took me some time and I was not a happy bunny.

The arrival of my 350 has seen a temporary diversion to tweak all of the settings to suit the model. This has taken a couple of days on & off but now things are pretty much how I want them to be. The extra room in the v4 chip has enabled me to include a couple of on-board announcements (one long one for an 'all-stations' service, and another shorter one for a 'limited stop' service). I've set the volume of these fairly low so they sound as if heard through the open doors when passengers are getting on and off.

A speaker has been fitted in the large battery box under the driving vehicle next to the motorised car. The sound is now better but the plan is do an identical fit in the other half of the train with a second chip and speaker. On a 3-car unit you can just about get away with a single chip and two speakers (one in the first and one in the third carriage) but with a four-car unit that's stretching it too much. Once I've done this and weathered the underfame I'll post a video.

I'll get back to that skip one day...
