OC-5 Octave

Vintage mode recreates the mono voice of the 1982 OC-2 with updated tracking and no audible latency. Poly mode adds chord-friendly octaves, and a Range control can limit the effect to lower notes or isolate the lowest note in a chord.

Dedicated Direct, +1 OCT, −1 OCT, and −2 OCT/Range levels cover three octaves of blend. A Guitar/Bass switch optimises tracking for each instrument, and Direct Out supports wet/dry splits to separate amps or channels.

The OC-5 keeps the standard BOSS compact footprint while expanding range and polyphony beyond earlier OC models in the series.
