Orca has a simple subtractive synthesis structure, being comprised of an oscillator, filter, fixed amp envelope, velocity sensitive filter envelope and an amp module. The monophonic voice engine in Orca runs at twice the hosts sample rate to reduce the aliasing caused by the non-linear analog modeling of the filter and amp modules. A voice priority of newest note is used, and every new note re-triggers the amp and filter envelopes.
The latest version supports disabling of animation which helps some users who have been experiencing large cpu usage due to graphics. The filter algorithm has also been updated for improved resonance drive.
