@Morphoice

I just tested the panel only method, it doesn't seem to work.

But using an invisible slider does, so I'm not sure why it's not working for you.

Here's my test snippet:

@David-Healey Thanks for testing. I think your working case is actually the same gesture thing seen from the other side.

In your example Knob1 is a real slider you drag directly, and it just mirrors its value into Panel1 for display. The knob is the parameter, and because it's a real slider being dragged, JUCE fires beginChangeGesture/endChangeGesture, so it reads back. The panel there is only a readout.

Mine is different: the panel is the thing being dragged. 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 pushes the value into the invisible slider with setValue/changed from script. The slider itself is never dragged, so no gesture fires, and Cubase records the lane but doesn't arm it for read until I reload the project.

So dragging a real slider directly works (your case), but I can't do that without losing handle-only, and driving the slider from script gives me handle-only but no gesture. As far as I can find there's no HISEScript API to emit beginChangeGesture/endChangeGesture.

So the real question: has anyone gotten host automation to read back on a script-driven control - one you set with setValue/changed rather than by dragging the actual slider - without a project reload?

[David Healey]

@Morphoice 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.

@Morphoice said in Custom controls:

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

[Morphoice]

@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
