This is a really good idea!
I worry that it might get too nested in terms of legibility, but a good solution to that would have whatever choice you pick (for the gradient area) be ‘sticky’. So unless you want to go and change a different thing, you don’t have to engage with that part of the menu.
I’ll think about how to best incorporate this idea, but I definitely like having a multi-purpose gradient area with different visual signifiers.
In TPV2 I was going to move the tilt stuff into a more global alt setting area, and figure out something else to do with a row-specific alt menu, but maybe all of that can get folded into one, especially since I plan on moving the slice/grain/combine/pattern out of there, and into the fingering system.
edit…
Actually splitting this into “configuration” stuff, which can go in a global alt menu, and “performance” stuff, which will go into a local alt menu is a good solution I think.
So things like overdub vs replace, playback mode (karma, mlr, tgc, tbl), mute groups, buffer select can go in the global config alt, and things like pitch, volume, tilt, can go in the local perform alt.
