Hi Matt,
Just to let you know Vital is pegging 100% of the CPU when used as a plugin on GarageBand on the Mac (Intel). As soon as the plugin is loaded, it is maxing out all 4 cores (showing ~400% usage in Activity Monitor). This happens before even playing a sound, and no other plugin I have does this.
It is running absolutely fine in standalone mode on the same Mac (around 20% of one core), so this is likely a problem with the plugin architecture you are using (JUCE?).
Hope you can get this sorted as Vital looks awesome and I’d love to try it out in a DAW.
