I make Max4live patches to play music with monome.

My patch work fine individually, however when patches begin grand or when I add differents patches, I think that it don't work anymore perfectly : I have some latency, for exemple, with my sequencer (to my external synthetiseur) or to launch clips in Live.

How to improvement performance in Max ? In the program ?
