Bullshit mate....64 bit has been awesome for me, all my plug-ins work perfectly fine and i personally would never look back to 32-bit versions....Have you even used the 64 bit version yourself??? you talk so much bollocks sometimes dude.
Dude you have to be the worst person on youtube for actually teaching people how to do stuff....the guy in the video asks you how to side chain via a send and you completely shut him down cos you have no clue like most of your videos. My tip would be to side chain using the clips volume envelope which can be accurately edited to however you like plus you would get that added benefit of being able to freeze that track and then bounce it to further save on RAM.
I would also recommend your viewers go watch Tom Cosm and Mr Bill use ableton...you will learn so much more!!
