@AHTV hmm that's weird, anything that shows in the interface designer should show up in the preview. What if you create a new project with 3.5.0? Does the knob appear then?
YESSS This solves my problem, thanks! Love your work on HISE, keep it up!
Thanks
@Lindon It's often an endless loop somewhere that isn't detected or a function that takes too long time to execute. Try to isolate the task in question and put it in a background thread. I had a lot of these errors recently while performing big operations on buffers and this did the trick.
@DanH Oh I forgot something. The ramp was not being setup correctly. I tried to add HISE modulators to a filter, along with the scriptnode one, so you can make an A/B test between using both solutions. Mine seem pretty smooth 😂
