Oh, I think I see it! ControlRulerWidget::setSegments, which makes
m_controlList, checks for a device of the right type - but it actually
only checks for MidiDevice.
Now I have to wonder how the other ruler buttons even work? I just
looked, and it's because we do the three types of ruler completely
differently!
Only pitchbend uses slotToggleControlRuler or checks m_controlList. So
not setting m_controlList for synth looks like a mistake. I'll patch it.
