A toggle for that "jump around" behavior would sure be great, huh!! Or just turning it off entirely...
Here's a terrible workaround: dedicate one of the other tracks to being the Ableton MIDI pass through. Like, set Track 1 Drum and Track 4 to the same MIDI out channel, send Ableton MIDI out to Track 4, now you can program the drum track without dealing with incoming notes. But you lose an entire track to this, so... it stinks!
