I think in many cases, horizontal sliders with labels and numerical values inside the slider area, are the better approach.
Like knobs, sliders can be done right or wrong too. Pick up a handy android device for examples of wrong. (In audio applications) I think it is the available ways of doing things on the android because even applications made by a company that also does a pc version, the android version is not as good.
In my opinion the best slider will allow the pointing device (finger or mouse) to be placed anywhere on the slider and moving the mouse will move the value from where it was in the direction the finger moves. (Ardour fader for example, but lots get this right)
The next best (best that can be done on android it seems) is that the value will not move untill you pass the current value.
The third best the value will not move unless the mouse or finger first touches at the current value.
Fourth best is having the value jump to where you first put the mouse or finger.
The worst one looks like second best... That is putting the mouse on the slider has no effect untill getting to the current value... but because the slider control "looks like" a real fader knob, the value first jumps in the oposite direction the mouse/finger is moving as soon as the mouse/finger touches the graphic of the fader knob rather than waiting till the finger is at the middle of the fader knob. This one is useless.
While horizontal faders can use less space (Ardour plugins use this) it becomes less "stage usable" real quick.
In the end, for stage a hardware controller seems the best. -- Len Ovens www.ovenwerks.net _______________________________________________ Linux-audio-dev mailing list Linux-audio-dev@lists.linuxaudio.org http://lists.linuxaudio.org/listinfo/linux-audio-dev
