Hello,
Basic recording and editing in Ardour can be realised almost without using the keyboard at all:
Anyway Pd beats both in simplicity by only requiring 6 special keyboard shortcuts: Ctl-1,...,5 and Ctl-e ;)
Just a quick note that I contradict the view that point and click == good user interface. Additionally I think mouse is a bad unnatural invention but that is because I suffer of carpal tunnel syndrome for years now which I only overcome with the use of graphic tablets but in general the distances you have to go back and forth with mouse is ridiculous and waste of time, particular when making music and having to interact in time. I experienced a high increase of productivity with learning the key shortcuts of applications and thinking about programming a sequencer which doesnt work with mouse anyway (but is not a tracker either, more MPC style). In general I think much about user interfaces and hope to come up with better ideas, point and click is so stoneage and its crazy to fit in all kind of application in this metaphor.
Physical hardware user interfaces are one solution, like control surfaces in the audio world. 3D is always a hassle because you usually manipulate 3D on 2D screen. My experience with datagloves is so lala having the bad P5 which is not precise, modelling with it would lead to funny results. And holding up hands in front of the screen is tiresome too. Same was with Lightpen on CRT monitors but both are gone now. I have no experiences with 3D mouses yet...
Cheers,
Malte
