[sdiy] Key spring colors on ARP synths

[Terje Winther]

Recently I have fixed some old ARP synths. They all needed a really good cleaning of the keyboard. And as you know; you need to remove those key springs to change key bushings and various other fixes.
The key springs have two colors; black and (dark) red. Supposedly because of different tensions for the white and black keys, since they have slightly different horizontal travel.

But here is where it gets strange:
Some of the synths I have fixed used black springs for black keys (sort of easy to remember), while other synths used the red ones for the black keys.
So which is correct? Or did ARP change this according to any sort of differences between the various versions of the Axxe and Odyssey etc.?

Anyone?
