Before the arrival of the V4.0 i was a fully satisfied ESU customer. Dozen of the Lopi Basic V1.0 and of the V3.0 were mounted and with some adjusting of the PID parameters the so equipped locos were moving without humming sounds.
Until the V4.0 arrived. The real bugbear is the poor motor management compared to it's precedessor V3.0.
Humming is one of the least problems. The motor drive seemed me optimized for those antique drivetrains like Märklin split field or Fleischmann or Lima pancakes or else pre war designs. There are so low frequencies in the motor drive, especially when the option of adaptible frequencies is on, just right to kill coreless coil motors.
No Sir this decoder ist not a step forward into the future, it is complex, it is more complicated than a Zimo, but has not the benefits of an Zimo.
A Zimo decoder is a nerd decoder, made by nerds for nerds.
This V4.0 is only complex, complicated and user unfriendly.
