MidiKeyboardComponent losing note

When I use a QWERTY keyboard to play notes via the MidiKeyboardComponent the notes hold even though I may start tweaking widgets with my mouse. This is the behaviour I expect. Whenever I move rotary sliders everything works fine and I can detune my synth with the mouse. While tweaking with any horizontal sliders the notes stop. It’s as if the sliders grab focus and cause a note-off to be sent. I’m not sure what the expected behaviour should be but I would have thought that all sliders behave the same in this regard. Any ideas on how I can make my horizontal sliders behave like my rotary ones?

p.s. I’m using the latest tip.

I guess you’d need to stop the labels inside those sliders from getting keyboard focus…

Thanks Jules, I’ll take a loot into it.
