I am going to start posting Max for Live objects here…

RationalREMIX.amxd Syncs master instance of a sample to Live’s tempo, and plays two time-stretched and pitch-shifted instances of the same file (update Mar. 3, 2011)

allnotesoff.amxd Especially useful if you are using solenoids, this is all notes off on every channel which runs after audio is stopped in Live. It checks through the range of a piano two octaves at a time to prevent risk of drawing too much power.(update Jun. 22, 2011)

harmonize.amxd Plays parallel relations to incoming MIDI. Super simple, but super useful for offsetting the starting pitch of an instrument who’s default is note 0 (instead of note 36, for example) or for parallel synth sounds.(update Jun. 22, 2011)
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

monome.axmdAdd this as an instrument anywhere you want to use the Monome on as many track as you like. It also has a note offset and counts tempo across the top in quarters or eighths. The lights going back to the Monome can be turned on or off.(update Jun. 22, 2011)
