VP4 OWNER'S MANUAL

Modifier Settings

The Modifier screen contains settings to control how the modifier works.
SOURCE
The Source is the controller that drives a modifier. There are 12 options:
Pedal 1, 2 – Use these to assign pedals or switches connected directly
ƒ
to the VP4. (See p. 13 for instructions on Pedal/Switch initial setup).
External 1, 2, 3, 4 – External Controllers allow you to assign MIDI
ƒ
CCs as modifier sources. They can also be set globally to either of
the onboard PEDAL jacks. To assign a CC or pedal globally to any
of the 4 External Controllers, open SETUP > MIDI Remote, scroll
down using SELECT, and then turn A to assign the desired value.
LFO A, LFO B, ADSR, Sequencer, Envelope – The VP4 includes
ƒ
four "Internal Controllers" that can be used as modifier sources.
Settings for these sources can be found in the Controllers menu
(p. 42) and are saved independently in every preset.
Pitch – The Pitch Detector analyzes the pitch of your playing and
ƒ
outputs a low value for low notes and a high value for high notes. It is
keyed to the lowest and highest notes on a standard 6-string guitar.
None – Assigning this controller removes the modifier from a parameter.

PARAMETER RANGE

The Range settings define Min and Max points for how the target parameter
responds to the source. These allow you to fine-tune sound changes.
EXAMPLE 1: A pedal assigned to Delay Feedback has Min at "10%" and Max
at "50%". The feedback sweeps only from 10% to 50% as the pedal is moved,
even though this parameter normally ranges from -100% to +100%.
EXAMPLE 2: The modifier for a pedal controlling Rotary Rate has Min at "0.67
Hz" and Max at "6.5 Hz" (classic "chorale" and "vibrato" speeds for a Leslie)
even though this parameter normally ranges from 0 Hz (parked) to 10 Hz.
MODIFIERS & CONTROLLERS

AUTO-ENGAGE

Auto-Engage engages or bypasses a block when the Source value changes.
If you've ever used a Wah without a toe switch, you'll easily understand the
concept: the Wah automatically activates when you push it forward and
bypasses when you pull it back. Auto-Engage works the same way but can be
applied to any modifiable parameter in any effect. Once you try it, you might
find it conveniently eliminates the need for expression pedal toe switches.
Auto-Engage has two settings:
Auto-Engage – This sets the auto-enage "mode".
◽ Choose "OFF" to disable Auto-Engage.
◽ POSITION ("POS") options trigger the effect based on OFF VALUE (see below).
◽ SPEED ("SPD") options engage the effect when the controller is moved quickly.
◽ The FAST, MEDIUM and SLOW options determine how quickly the effect turns
ON or OFF once Auto-Engage is triggered.
Use SLOW to "relax" Auto-Engage, so it doesn't switch off too suddenly.
Off Value – Sets the threshold that the source must cross for auto-engage to
occur. If Off Value is below 50%, the effect bypasses when the controller goes
below the threshold. If it's set to 50% or higher, the effect bypasses when the
controller goes above the threshold.
For "heel down = bypassed," set to 5%. For "toe down = bypassed," use 95%.
PERFORMANCE
Update Rate
slow is in fact still very fast, and fine for the vast majority of applications.
The faster settings require additional CPU but provide even smoother sound
performance when ultra fast changes are required (while using a fast LFO on
a filter, for instance). Adjust this setting if you think you hear "zipper noise"
while a modifier is in use.

EXPERT OPTIONS
