8. The factory setting for the INST output of the V256 is 100% dry instrument signal only.

In order to use the V256 in this mode the INST output blend needs to be adjusted.

9. Hold down the MIC BYPASS footswitch and adjust the BLEND knob. Fully CCW is 100%

instrument signal. As you turn the knob CW more V256 effect signal is added and at
noon, the mix of dry instrument to V256 effect will be even. As you continue to turn the
knob CW past noon, the dry instrument level will decrease and at fully CW the mix will
be 100% V256 effect.

10. After the BLEND knob is adjusted for the desired mix, release the MIC BYPASS

footswitch and the instrument output mix will be set. If the MIC BYPASS is not held
down, moving the blend knob will make no difference to the INST output mix.

- DESCRIPTION OF MODES -

The V256 has 9 modes to choose from. Each mode gives the musician a different sonic
palette to work with. In addition, each mode may change the functionality of some of the
V256’s knobs. In this section we will describe each mode and the functionality of the knobs
that change with each mode.

Use the MODE knob to scroll through the 9 modes. Turning the MODE knob clockwise goes
up the LED ladder. Turning the MODE knob counter-clockwise goes down the LED ladder.

Below is a table displaying the function of each knob as it relates to a selected mode. Arrows
indicate the function that occurs as the knob is turned to or towards the extreme knob
position in that direction. The up arrows indicate the center position of the knob.
