Summary0008964: Aux Send reaction on mouse scrolling is slow
DescriptionThere is principally a good mechanism in ardour using the scroll wheel on faders:
* Just scroll wheel: fast
* Scroll wheel with Ctrl pressed: slow
* Scroll wheel with Ctrl+Alt pressed: very slow

There is an exception of this rule. When using the scroll wheel on auxiliary sends, it goes:
* Just scroll wheel: slow
* Scroll wheel with Ctrl pressed: very slow
* Scroll wheel with Ctrl+Alt pressed: slightly before "no move at all"

I wonder if this is intended. If not, I'd love to see this behavior changed to one I experienced on other faders.
Steps To ReproduceUse a channel strip with an auxiliary send, set the pointer over it and scroll.
TagsNo tags attached.

This is mysterious. There should be no difference and scroll-wheel works exactly the same (also the small inline fader).

Do you have a mouse with a latching (clicking) scroll-wheel, or do you use a touch-pad (or middle-click scroll emulation)?
I'm asking because the inline fader reacts to both horizontal and vertical scroll, with a touch-pad, a diagonal scroll can cancel out any changes.

I cannot reproduce the issue here (nor can other users I've just asked on IRC).

Yes, I do have a latching scroll wheel. My preferred input device is a wired "Logitech Track Man Wheel" trackball. But I have mice with which I had the same result.
To be more precise I show you the dB change I'm getting delivered.

Faders (edit window or main fader of mixer window), count from 0.0 dB:
* Scroll wheel only: -5.7 dB / (+)4.7 dB for 5 scroll events from latch to latch.
* with CTRL: -0.1 dB / (+)0.1 dB for each scroll event.
* with CTRL and Alt, you need 10 events to scroll +/-0.1dB

This is totally okay for me. A very good experience.

Auxiliary Sends, count from 0.0 dB:
* Scroll wheel only: -5.69 dB / (+)4.71 dB for 5 scroll events. (Seems to be identical with the faders behavior. My fault! I had this wrong in my mind when writing the bug report!)
* with CTRL, I need between 3 and 5 scroll events to get +/-0.01 dB (I mean 0.01, not 0.1!)
* with CTRL and Alt, you need 45 scroll events to get +/-0.01 dB

Just in case, you're still getting other results: I'm using german locales. In rare cases, some programs can't deal with this or showing strange behaviors like this… But of course, it can also relate to Ubuntu's build options…

Can this behavior be reproduced?
