In the words of GFI System:

Orca packs four quintessential GFI System delay algorithms into a compact pedal that is straightforward and easy to use. Intuitive user interface coupled with an LCD screen make it a breeze to navigate through Orcas vast sonic palette and features.

• Input/Output: Orca supports both mono and stereo input/output. Mono connection is made using standard TS patch cables while stereo connection is made via TRS patch cables (a splitter-Y cable may be needed).
• External control:A multi-purpose jack provides connection to an expression pedal or tap-tempo pedal.
• Expression pedal input enables expressive control over delay parameters while external tap-tempo can be used for remote tempo control.
