How do I have MIDI inputs only affect in half of the range?

Post by booshtukka »

I have a bunch of pots on my DJ mixer (DJM-900NXS2) I have affecting various things in Resolume. But I can't figure out how to have them take no effect when they're in the centre.

For example, I have an EQ bass knob. In the centre it has no effect, to the left it removes bass, to the right it increases it. I'd like to map this to a control, but only when it's turned to the left - when it's in the centre I'd like it to have zero effect.

I also have a filter knob that behaves the same way. And the king of these controls, the cross-fader! This would be hugely useful. Can it be done?

Maybe with envelopes:

Set the middle keyframe to the param's default value

Aha! This totally works! Amazing!

I was really confused for a while, because although it was working correctly, the V slider for the layer wasn't actually showing the Opacity value. Perhaps a bug?

But regardless, it works exactly as I want it to! I'M HAVING SO MUCH FUN!

Great to hear you're having fun :)

With an envelope enabled, you might see two green lines on the param slider.
The bold one is the parameter phase, the slim one is the actual param value.
With a linear envelope, these are at the same positions.
Midi shortcuts control the parameter phase.

What I mean is on the big V slider that I see to the left of the Layer, sometimes it is showing a non-zero value when actually the effective Opacity is zero - so I found that a bit confusing and thought I was doing something wrong. :)

That's what envelopes do, they modify the input curve.

I get it. I understand how they work. What I mean is, the input is modified, so the result is e.g. 75% opacity. But the big V slider shows 100% opacity. I would find it more intuitive if the V slider showed the calculated result rather than the input result. :)

The V slider is the input. If it would show the result, you wouldn't be able to drag it, with a random envelope.

We have draw a thin line on the parameter sliders on the panels with Envelope to show the actual modified value, we have a ticket to have it shown on the layer controls.

That makes perfect sense - and that line would make it visible. Thank you!
