It might be a bit obvious but what is the best way of bypass in Max ? For example if i have a delay effect that i want to bypass. Any suggestions ?

bypass

if you want to free processing power put it in a poly and bypass it by loading an alternative through only patch in that poly. If its only to bypass you might use selector~ at the end of your chain or gate~ at the beginning or a matrix~ anywhere

The [matrix~] object is probably the way to go due to the built in ramp time that will smooth the changeover.

I was thinking something that is similar ro a guitar effects set-up ... For example if I have an In, Delay, Flanger, Reverb and Out in the same line, what is the best way to bypass one of these effects ?

did you check the "Max 5 Guitar Processor" tutorial?
