Understood Max. I started off the hard way with CVs (in Hex even) as I had a Digitrax system in 1994. Next we got the luxury of Decimal, and then the revelation that is JMRI. A big THANK YOU to the entire JMRI team! 
N.B. I have never used the Lokprogrammer so take this with a pinch of salt... I downloaded the app and it seems there's a setting under "Decoder > Change decoder settings > Motor Settings > Adaptive regulation frequency. This is a checkbox, and I'm not 100% clear from the manual if it's plain vanilla "off" or "on", or whether it's "off" and "on plus adjustment with the Back EMF sampling period slider underneath". But hopefully a bit of fiddling and user manual interpretation will get you where you need to be. 
Once again I am living vicariously through your efforts in the hope of learning that Loksound 4 XL will be my decoder of choice for Pittman powered locos (where ESU has the right sound set). I am highly impressed that you produce your own sound sets by the way - I can't imagine the learning curve to get to that stage!
