so there is, indeed, in Live, this magical "midi learn" toggle that lets you assign any midi you want (or nearly) to a clicked Live UI butotn toggle dial or whatever. You cna, this way, assign in one click, midi control to your m4l UI objects inside your m4l patches.
I was wondering if, inside this time Max and without Live, tehre was any way at all to reproduce this, ie having a m4l api object which you feed a toggle and maybe a parameter file load/save, and when toggle activates it, any m4l ui object inside Max would be ready to be MIDI learnt. It would sound logical and easy to do (for m4l developpers), but maybe i am wrong. I don't know m4l that well, hence maybe it's one of those basic things i've missed... anyway, is there something like this ?
