Hi all.
I found a solution thanks to @bjoluc at API: mOnTitleChange and mOnColorChange broken for some bindings - #20 by bjoluc
In the @robw script find the line with
page.makeValueBinding(faderSurfaceValue, hostMixerBankChannel.mValue.mVolume).setValueTakeOverModeJump().setSubPage(subPageFaderVolume)
and duplicate it.
For me it works. It’s strange, but it works. Thank you @bjoluc . Maybe a future update breaks the script again but meanwhile.
