KiloHearts’ MultiPass plugin can split incoming audio into multiple frequency bands and apply FX chains to each of them in parallel. It can then output each of the processed bands to separate outputs (like Kontakt or Falcon can route instruments to separate outputs).
I know how to access those outputs in Bitwig, Live and Reason, but have no idea how to do that in Cubase (or Studio One, for that matter).
Any ideas?
