Why do audio automation nodes and MIDI control lane nodes behave differently when using the scale tools?
Please see the difference in the these screen recording clips.
In MIDI editing the tool scales the outer nodes without creating new nodes. In audio automation editing the tool creates new outer nodes.
The first difference, that the shape of the curve inside the selected range changes is, because Volume works on a logarithmic scale compared the linear scale in midi.
The second difference, that the midi cc curve changes outside of the selected range to smoothly connect with the nearest data point inside the selected range, is actually the Ramp/Curve algorithm, that shapes the CC curves into smooth curves, with less data points. If you put the midi cc to step mode, it will behave similar to the Audio curve.
You can use this, if you want the audio editing similar to the midi CC editing:
Sure, that’s an option. But I still don’t understand why it have to create two new nodes at the border of the selection.
In my opinion it would’ve been easier if it were like in Logic; you click and hold in the middle of two paint and drag up and down for adjustment. In Cubase there is a similar option but it sill creates two nodes over the existing ones.
It’s creating new nodes at the border, because that way you’re only changing things inside the range selection you specified, and outside of the range everything stays exactly the same as it was before. That’s the default behavior for both Volume editing and Midi Editing (without the Ramp/Curve algorithm).
You may not like it but it is logical and there are people who prefer that the range selection tool only change things that are inside the selected range.
