From GFI:
Orca packs four quintessential GFI System’s delay algorithms into a compact pedal that is straightforward and easy to use. Intuitive user interface coupled with an LCD screen makes it a breeze to navigate through Orca’s vast sonic palate and features.
Input/Output
Orca supports both mono and stereo input/output. Mono connection is made using standard TS patch cables while stereo connections is made via TRS patch cables (a splitter-Y cable may be needed).
Â
External control
A multi-purpose jack provides connection to an expression pedal or tap-tempo pedal.
Expression pedal input enables expressive control over the delays’ parameters, and the external tap-tempo can be used for remote tempo control.
