Or buy yourself a ROlli keyboard and have each finger send seperate midi info , ie midi channel and cc and aftertouch . I have ordered mine but delivery is not expected for a while. In the meantime I am hoping someone can develop a midi fx script for logic .re note expression : obviously useful but unless I have not got it , it seems it is just a post recording editing feature rather than a live input one. ie the point of auto divisi is to be able to avoid editing your parts and hear the beauty of the seperate sections in real time on the fly which is more inspirational and quicker.
Seperate tracks is a great way of working for the most realistic demos but I am also wanting a shortcut version for sketching and composing that allows you to hear a full section when writing say a string pad that isnt everyone playing the same notes. Lass is close but I prefer the DImension strings sound.
