The AU spec allows plug-ins to know if they're processing 'silence' and/or to tell subsequent plug-ins that their output is silent. Live supports this fine, and this is the usual method for saving CPU on plug-ins that aren't actually processing any input. However, it relies on the plug-ins actually implementing this - I'm sure many ignore it and just process the incoming audio regardless. In my Live rig I have a number of effects set up and then automate their on/off switch (top left of the Live unit for the plug-in). Seems to work fine. NB muting a chain in a rack is not the same as actually powering off the plug-ins in that chain. cheers, os. 2009/6/2 Simeon Harris <simeonharris40@googlemail.com>: > well ok then...i thought my question might be too esoteric to be of much > interest...but here goes...and it relates to Live 8 > > this is basically an extension of the rack>laptop thread > > i really like the plugins in Live and i'd like to use them in conjunction > with my favourite AU plugins to replace my rack of fx > > i've successfully managed to put augustus loop and sooperlooper in a >couple > of aux channels and control them fine...it's the main fx chains that are > giving me a headache > > ideally i'd like to set up one chain of fx with all the plugins i'll need > and then just turn them on and off and recall a preset into the ones i >want > on, but Live wants me to chain up all the fx i want for a particular >sound > in a rack and recall that particular chain with a cc value. this gives >me a > couple of problems...one is that Live doesn't respond to program change > messages (which my footcontroller sends out), but i've solved this by > transforming these into cc messages by using MidiPipe. the other problem >is > the sheer number and complexity of the chains i'll need...maybe up to > 60...and with many of those containing instances of Reaktor, the CPU load > will be massive (i don't think Live behaves like Mainstage, effectively > turning off plugins that aren't in use and saving on CPU...but i might be > wrong). one solution may be to create racks out of the Live plugins, but >not > out of the AU plugins. most AU plugins allow their presets to be recalled > via program change messages and both the PC and CC messages i'm sending >are > being received...but i can't seem to get Reaktor to respond when it's a > plugin (the standalone behaves perfectly). > anybody got any ideas how i can stay with a "preset" modus operandi and >make > it all work in Live? if Live turns off plugins that aren't currently >loaded, > then it should be fine and i'll try and experiment with this further, >but if > not i think i'm a bit stuck. > i did play around with Bidule for a bit and yes, this kind of thing is a >bit > easier, but it seemed less stable at the latency settings i liked and it > doesn't have the plugins that Live has > > cheers! > > sim > > -- os@collective.co.uk http://www.darkroomtheband.net/ http://www.expert-sleepers.co.uk/
