Mine is that Native Instruments plugin called Razor. It’s an additive synth that devours your CPU without mercy. The worst part is that it’s not even that high of a quality synth, compared to similar CPU hogs like Omnisphere or Diva.
Actually, gotta be honest with you, u-he Diva and Dmitry Sches’ synth Diversion win my vote. They are CPU hoarders, and I vote them each about the same as far as usage (with the assumption that the oversampling is at it’s highest setting when using Diversion).
yes tremor is a cpu- hog. but i guess the reason for this is some coding issue. maybe even denormalisation- issues.
the plugin gives huge cpu spikes when stopping and playing the host.
i have some reaktor patches from the user library that have ~80% on a new cpu.
iirc tassman 4 by a.a.s. is also a bit mre intensive.
oh and there is a spectral effect toolbox. that can get very hungry. but cant remember the name right now.
idunno what’s up with fxpansion … i have the issue with geist. C’mon man, it’s not even doing synthesis and it eats massive chunks of cpu cycles. The effects don’t sound that good…
Tremor sounds a bit ridiculous. For now I’ll stick to microtonic and drum synthesis in zebralette…
