Is replacing the weights possible or is it a permanent part of the key? Etc...
Would Korg sell weights to my tech who is an authorized Korg Servicer? |

I opened my Kronos quite a few times to do the mods I wanted, which sometimes implied to disassemble/reassemble the RH3 action.
The RH3 key levers which act as "weights" are next to indestructible, so I wonder why you are looking to replace them. Maybe you could give more details. |

To create a lighter balanced action that is still weighted yet lighter and consistent across the board and less sluggish in the bass.
I have no idea how the action is constructed. Whether the weights are even a separate part in the action or not. I won't want to do anything that is problematic with a chance or screwing up the instrument. |

Hi there,
For this you would need to disassemble the whole action (not easy) and then cut the 88 metal levers, hoping the new resulting weight would be what you expect. I remember someone doing this some years ago here. I would not try such a mod, as it is simply too risky. |

Thanks.
No I wouldn't do that. Only if the weights were detachable and replaceable parts and I could get Korg to provide the replacement parts.
Thanks again. |

|
|
I did a key weight mod last week on my Kronos 2 73.
Took a reciprocating saw and cut off between 3-6 grams per key (more lower and less higher).
While I couldn't get super accurate, I just weighed the downweight on keys and glued back on some metal in areas that got cut a little too deep.
Message me if you want more details....

I recently got a Roland A-800Pro (61 key) midi controller to use when playing sounds on the Kronos that don't work with the heavy-weighted keys (like synth lead or organ or harpsichord.)
I got it because from what I'd read it was the lightest synth/keyboard action around on new keyboards these days. It seems like the inexpensive midi controllers have pretty strong "springs" in them these days, too much resistance for what I was looking for.
Anyway, an external controller sounds more fun to me than using a saw.  FYI if someone does try that Roland, note that it requires a USB chord for power AND an old-school MIDI chord as well. You also have to toggle a setting called MIDI I/F Switch setting to "OFF" ("On" if you're using it with your computer, off if you're using it to control another keyboard.) |

| There are 2 types of USB options on your Roland board. I think if you want to use your Roland via USB cord only for both power and MIDI, you need to go into its settings and change the USB option. |
