Sound decoder install project

[Schraddel]

If it may help here the CVs of some sound equipped locos which had before a jerky start and stop behavior:

Atlas Genset 2 (with the new not so good motor as before) :
CV10: BEMF cutout 0
CV 67: 3
CV 68: 5
Then a straight line to
CV94: 109
CV209: KP Coefficient 24
CV210: KI Coefficient 10
CV212: Motor Control Intensity (BEMF Feedback Intensity) 255 (100%)
CV213: Motor Control Sample 15
CV214: Motor Control Aperture Time 15
CV215: BEMF Gain Coefficient 2 = ON
CV216: Voltage Adjustement (DCC RMS Voltage) 140




Athearn Genesis GP9 (Roco motor) with OEM Sound:
CV10: BEMF cutout 0
CV 67: 3
CV 68: 7
Then a straight line to
CV94: 128
CV209: KP Coefficient 80
CV210: KI Coefficient 2
CV212: Motor Control Intensity (BEMF Feedback Intensity) 255 (100%)
CV213: Motor Control Sample 15
CV214: Motor Control Aperture Time 15
CV215: BEMF Gain Coefficient 2 = ON
CV216: Voltage Adjustement (DCC RMS Voltage) 140



Bachmann ALCO S-2 (Bachmann motor, a not so good runner) with OEM Sound
CV10: BEMF cutout 0
CV 67: 1
CV 68: 4
Then a straight line to
CV94: 128
CV209: KP Coefficient 30
CV210: KI Coefficient 10
CV212: Motor Control Intensity (BEMF Feedback Intensity) 255 (100%)
CV213: Motor Control Sample 11
CV214: Motor Control Aperture Time 20
CV215: BEMF Gain Coefficient 2 = ON
CV216: Voltage Adjustement (DCC RMS Voltage) 140

I hope this may help you to set your decoders, after changing the CVs the starts and stops smoothens out. And all will used for switching duties.
