I was demonstrating the host automaton on the slider (invisible in your case) updates the panel

Right, but in your demo you're dragging the knob. We're not - we drag a view (panel) that sets the knob's value from script. A real drag fires beginChangeGesture/endChangeGesture, which is what arms the parameter for read; a script setValue/changed doesn't. So the host writes our automation but won't read it back until reload. The knob itself automating fine was never the issue - it's that our value comes from script, not a drag, and there's no script API to emit the gesture.

I get it, from the automations point of view you need it to work both ways - changing the knob sets the panel's value and triggers the paint routine, dragging the panel changes the knob's value.

In the knob's callback you put panel.setValue(value); panel.repaint();

[Morphoice]

@David-Healey Yep, that's exactly what I have. The invisible knob is the parameter and its control callback does panel.setValue(value); panel.repaint();. That half works - if the knob receives a value, the panel follows it.

The gap is on the write side, not the read side. I never drag the knob - I drag the panel, because I need handle-only dragging (move only when you grab the handle, not when you click the groove), which a normal slider can't do. So the panel intercepts the mouse and sets the knob's value from script. A real drag fires beginChangeGesture/endChangeGesture, and that's what tells the host to arm the parameter for automation read. A scripted setValue/changed doesn't fire it, so the host records my lane but never arms it - on playback it never sends the value back to the knob, the callback never runs, the panel never moves. A project reload fixes it because the host re-reads the parameter list.

So the knob->panel read path you're showing is already in place and fine. The only missing piece is that my value change comes from script rather than a drag, and there's no HISEScript API to emit the gesture.

Oh I missed that, I'll check

I wonder if my best option is to simply modify HISE to give the slider a thumb-only mode (gate that Slider::mouseDown call in HiSlider on getPositionOfValue) and throw the stack away

@David-Healey using the knob's control callback for the read side is cleaner than the poll I was using, so thanks for that. But I think the reason it works for you and not me is the host. Nothing here emits beginChangeGesture/endChangeGesture - Knob1.changed() from script doesn't - and Cubase only arms a parameter for automation read once it has seen that gesture. Your host seems to arm on a plain edit, so the round-trip fires; in Cubase the lane is written but never armed, so the read is never sent back and onKnob1Control never runs (until a project reload). So I think your test actually pins it on Cubase's gesture requirement rather than the link logic.

[David Healey]

@Morphoice Did you test my snippet?

[Morphoice]

@David-Healey at it. If this works in Cubase I'm gonna cry

[Morphoice]

@David-Healey Confirmed in your own snippet: if I write the automation by moving the knob from script (panel -> Knob1.setValue/changed) instead of dragging it, Cubase records the lane but won't read it back on playback until I reload the project.

[David Healey]

@Morphoice Which OS? I'm going to try this

[Morphoice]

@David-Healey I'm on MAC

[David Healey]

@Morphoice I'm not sure why, because I don't really know Cubase, but the panel is able to read/write automation in my test, even though I didn't set it as a plugin parameter in my snippet.

Edit: Aha, in the xml I see this

  <Component type="ScriptPanel" id="Panel1" x="70" y="180" width="330" height="250"
             isPluginParameter="1" allowCallbacks="Clicks Only" max="10.0"

[Morphoice]

@David-Healey I rewired a test slider in my plugin as a panel-as-parameter exactly like you did in your example, no change in Cubase. I'm attempting to patch HISE to have that handle click gated
