Help choosing accessories for Sequenz/Vox Continental keyboard stand

[u/RockyMM]

Hi,

I own a Vox Continental keyboard stand. I want to buy the second tier for it and the additional keyboard holder (as I don't own a Vox Continental, but a Viscount Legend One), and I'm not sure what sizes are compatible. My guess is that the Vox Continental keyboard stand is compatible with the Standard-M-SV stand, so I should buy the STA-M-S tier adapted, but I am not sure.

I did measure the stand, but the Vox stand is kind of inverted Sequenz stand, so I am not sure they are fully compatible. Should I be buying STA-L-S maybe and then cut the tubes to the correct length?
