Thanks, seems ridiculous to me, Ableton works the way i want, but i hate the rest of it, somebody somewhere has to know or know why it does this, having two of the same midi note playgin at once makes NO sense, NONE, thats why ALL and i mean ALL hardware and other software sequencers work the same way drum machines do in this respect, erasing the note you overwrite. Logic is the best DAW i've used but i still must program all my drums (and i program 'live' drums using DFH and BFD not loops and other such things) using my old MPC 2000xl, i hate working on the bloody thing now, it's so slow but does enable me to get the feel i want for EVERY stroke by PLAYING IT, not adjusting after with a friggin mouse.
(and deleting duplcates! YUK!)
