Posted: Sat Jan 22, 2022 12:37 pm Post subject: Nautilus half damper compatibility |
|
|
Hello - I am absolutely brand new to keyboards (Nautilus is my first), although I have played acoustic piano off and on over the years.
I have a proline half damper pedal which seemed to calibrate correctly in the Nautilus (it recognized it and didn't give an error message). The full damper function works correctly. However I don't detect an difference between full and half pedal when I half pedal. As far as I know everything is enabled in setup - not sure where to go from here??
I had a Yamaha pedal that the Nautilus would not recognize so picked up the Proline. Is the Proline incompatible with the Nautilus? If so what would you recommend?
Thanks very much for any assistance. Cheers _________________ Buzz |

Information on the Proline pedals is rather sketchy. If the pedal is the Proline PSS1 or PSS2, then it only seems to have a momentary, switch type characteristic, rather than a potentiometer, which is continuously variable, and necessary for the half damper function to work. To check the pedal, measure the resistance between the tip and sleeve connections on the jack plug, without allowing your fingers to short across the test meter probes. If the resistance changes suddenly as the pedal is pressed, then it is a simple sustain pedal. If the resistance changes gradually between 0 ohms and somewhere between 10k and 30kohms, as the pedal is pressed slowly down, then it is a half damper pedal, and should work. The Korg DS-1H half damper pedal has a 30kohm potentiometer inside.

Thanks for the reply. I did check the resistance and found that it acted more like a switch depending on the meter range setting. What was interesting is that in the lower meter resistance range (10-1K ohms) the pedal acts like a potentiometer. In the higher resistance range (1K - 100K ohms) it acts more like a switch. I'll see if I can learn anything from Proline. Thanks again for quick response! _________________ Buzz |

Just for the sake of clarity, the Korg DS-1H pedal resistance between jack plug tip and sleeve, varies from 30kohms in the pedal up position to about 1kohm, pedal down.
The Nautilus will expect a smooth increase in resistance as the pedal is moved through its travel. It might calibrate and work OK with 10kohms, but not with 1kohm.
