TC-Helicon Perform-VE Reference Manual (Preliminary)
Introduction
Thank you for purchasing Perform-VE!
Your new mic stand-mounted vocal processor opens up a world of sound creation and performance
opportunities.
Starting with our Adaptive Tone (automatic EQ, De-Essing, Gating and Compression), your voice will punch
through the mix and sound great in any environment.
Next up, an impressive assortment of transformations await your voice: HardTune Pitch Correction, Doubling,
Shift and Gender Morphing all work together to create whatever modern lead vocal sound you can dream up.
Perform VE also generates MIDI Voices to accompany your Lead. MIDI Voices can be pitch perfect vocal
harmonies, virtual analog vocoder voices, or VSS (Vocal Sampling Synthesis) samples that you record on the fly.
Simply play notes on a connected MIDI controller keyboard and you can have up to nine of these MIDI voices
singing along with your Lead.
You also get XFX for stutter, rhythmic, ring mod and flanger effects, Echo for spacious reverbs and beat-synced
delays, and Filter for a selection of transducer and sweepable filters. With all this at your command, you’ll
quickly generate striking vocal effects and exciting, fresh sounds that will take your music to new levels.
But wait, there’s more!
Perform-VE also includes a Drum and Audio Looper with several different kick, snare and hi-hat sounds available.
You can easily build a beat and then record a synchronized audio loop from Perform VE’s internal signal path.
Just tap and vocalize.
Read the Quick Start!
If you’ve read the Quick Start Guide that came in the box, hooked up a microphone, and can hear your music
and vocals coming through the outputs, you are already skimming the top features of Perform-VE. If you want to
get into Perform-VE’s deeper capabilities with this reference manual, we’ll need to do a little more set up. Don’t
worry – it won’t take long!

Connection Diagram
Perform-VE has a lot of connectivity:
•MIDI data is received via the mini-USB port or the 5-Pin MIDI Socket.
•MIDI data is transmitted via the mini-USB port.
•The PEDAL input allows you to connect a Switch-3 or Switch-6 (sold separately) to change presets, toggle
effects and control the LOOPER and SAMPLE features.
•The AUX input lets you mix stereo audio tracks with Perform-VE’s output.
•The balanced stereo outputs allow connection to any ¼” input equipped mixer or powered speaker
system.
•The XLR input is a MIDAS microphone preamplifier, providing the much-loved MIDAS soft clipping
characteristic sound when pushed hard.
For learning purposes, we recommend that you connect a MIDI keyboard to your Perform-VE while you track
along with this reference manual. Your MIDI keyboard will ideally be connected directly to Perform-VE’s 5-Pin
MIDI port as shown above.
Alternatively, your MIDI keyboard can be connected via USB cable to a laptop running music software that
features a MIDI soft THRU capability. You would then connect Perform-VE to the laptop via a second USB cable
and configure your DAW to take incoming MIDI from the USB MIDI keyboard and pass it on to Perform-VE’s USB
port. See your respective software manual for details on how to set up your particular system.

The Set Button
Configures: Microphone Input Level,
MIDI Channel Select,
MIDI Split Point Select,
& More…
Once a microphone and a MIDI keyboard are connected to your Perform-VE, it’s time to ensure that the audio
and MIDI settings are correct. You achieve this with the SET button.
The SET button performs a lot of functions in your Perform-VE. By itself, the SET button configures the mic input
level and sets the MIDI channel and split-point used to control the Notes, Vocoder and Sample features of your
unit.
Mic Gain Setting
The actual signal level coming from your microphone can vary depending on what type of microphone you have
connected and how loudly you vocalize (speak/sing/shout/shriek) into it. The Auto-Gain procedure is the easiest
way to ensure the microphone preamplifier level set within your Perform-VE is calibrated to match your mic and
vocal technique, but you have the freedom to set the Mic Gain level manually if you prefer.
Auto-Gain
Press and Hold the SET button to activate the Auto-Gain procedure and vocalize into the microphone at your
typical loudest volume. After several seconds the SET button will flash red, indicating that the procedure is
complete.
You will see that the LED to the right of the SET button changes color when you vocalize into the microphone.
This LED is a VU Meter, with the following color codes:
Green
-23dB … -13.5dB
Good Level
Yellow
-13.5dB…-7.5dB
Hot level, but
still okay.
Orange
-4dB … 0dB
Soft-clipping:
Midas Tone.
Red
0dB
Hard-
clipping!
If you find the Auto-Gain procedure set the input trim too low or high for your liking, you can always run Auto-
Gain again or you can set the gain manually.
Manual Gain
Press and Release the SET button to edit the Manual Gain with the Control Knob.
The red LED segments indicate gain provided by Perform-VE’s analog microphone preamplifier circuit. When the
mic-pre is at maximum gain, further gain is possible via digital amplification (the remaining 4 magenta LED
segments).
Once you stop editing with the Control Knob, the LED ring will return to the MIDI/LEAD mix display after two
seconds. You can then vocalize into your microphone and confirm the gain settings are correct for your
application.

5
HINT: Red in VU meter LED is not a good thing as it means hard clipping and digital distortion! Reduce the
microphone gain and try again if you see the VU LED turning red when you are vocalizing.
MIDI Channel
The MIDI channel that Perform-VE responds to is actually set during the Auto-Gain procedure if a MIDI note
event is received while the SET button is held down.
To set the MIDI Channel (without a split point):
•Press and Hold the SET button,
•Play a single MIDI note on your controller,
•Release the SET button.
Don’t worry about having to repeat the Auto-Gain on the microphone – these steps will not overwrite your
previous microphone level settings while the SET button is down, provided you stay quiet… so, shh!
When complete, you can verify Perform-VE is set to receive on the correct MIDI channel for your keyboard by
playing notes and monitoring the SET button; the SET button will flash red whenever MIDI note events are
received on the configured MIDI channel.
Even more SET button powers!
You can also configure Perform-VE to ignore MIDI notes above or below a user-defined note value. This is called
a Split Point. A split point is useful when you want to control an instrument other than Perform-VE with one part
of your keyboard, but still want Perform-VE to respond to keys pressed on the remaining keys. Split points with
optional octave shifts are explained in detail at the end of this manual in the MIDI Implementation section.
When combined with other button presses, the SET button also configures Adaptive Tone, Phantom Power, MP-
75/MP-76 Mic support, Drum Looper features, and will even dump effect presets via MIDI. Please see the
relevant sections later in this manual for details.
Now that your Perform-VE is set up and connected to the devices of your choosing, we’re going to take a quick
tour of the front panel, explaining what each of the buttons do without getting too deep in any details just yet.
Don’t worry – we’ll go feature diving soon enough!

One Knob To Rule Them All
By default, Perform-VE’s Control Knob edits the mix between the MIDI Voices and your Lead Voice. It applies to
all three presets and is not stored when Perform-VE is turned off.
LEAD Voice: Your voice. Enhanced and extremely
altered, just how you want it!
MIDI Voices: Up to 9 MIDI Note controlled voices
generated by Perform-VE to
accompany your LEAD Voice.
MIDI Voices are Harmony, Vocoder
or VSS Sampler Voices.
The graphic above shows equal levels of MIDI and LEAD as displayed on the LED Ring. From here you can dial
down the blue MIDI level by turning the knob counter-clockwise, or dial down the green LEAD level by turning
the knob clockwise. Whichever level you turn down, the other one will stay at max volume.
Effects
Perform-VE makes some of the wildest and most complex sounds that TC-Helicon has ever made possible.
There’s a lot to discover by simply pushing buttons and combining sounds, but we’ll give you an overview of the
basics here, starting with the six effects buttons, as shown below:
Toggling the Effects
Quickly pressing and releasing any one of the FX buttons will toggle the associated effect on and off. The LED
ring will switch to an alternate display mode while the button is down. There’s a reason for this momentary
flash, and we’ll explain it now.

7
Tweaking the Effects
Don’t like the Double, Morph or Echo that you hear? No problem, you can tweak several parameters of each
effect.
Each effect button is labeled with light gray text in one or more corners of the button. If you press and hold
“Level” (for example) in the top left corner of the Double button, then turn the Control Knob, you’ll adjust the
amount of doubling. Alternatively, if you press and hold the “Style” area in the bottom right corner of the
Double button, you’ll change the doubling style when you turn the Control Knob.
Every corner parameter label can be held down to edit that particular parameter with the Control Knob.
When a parameter edit is underway…
•The LED ring will display the currently selected parameter value,
•The Control Knob will edit this parameter, ranging (clockwise) from min to max, and
•The pressed FX button will pulse on and off. At this point you won’t need to keep holding it down to
continue editing.
To exit a parameter edit simply tap the active FX button again, or tap a different FX button. This will either
return the Control Knob to MIDI-LEAD Mix editing, or switch the Control Knob to editing the corner parameter
closest to where you actually pressed the new FX button.
Styles and Mods
In addition to parameters like Level, Shift, Gender, Mode, Key, Div, Delay and Reverb, you’ll see that four of the
effects have a Style parameter. Styles are essentially mini-presets for the effect in question. Changing any style
will instantly update a number of deeper effect parameters that are not available for direct Control Knob
editing. Style selections appear on the LED Ring as single color-coded LEDs.
Mods are related to the currently selected Style. They appear as levels on the LED Ring, colored to match the
Style. You can think of each mod as custom ‘Tweak’ parameter matched to the Style in question.
Now that the basics are out of the way, let’s check out Perform-VE’s effects!

8
Double
Applies to: LEAD Voice
Double simulates the classic “double tracked” studio sound that’s common on recordings of all genres. Double
Style selections can include Octave Up and Octave Down voices, for an even thicker effect.
Double Style
Double Level
Double Level changes the amount of doubled voice, relative
your lead vocal.
On the ring, Level is indicated by one up to all LEDs lit, in
the color of the current style.
Range: Off, -10 to 0 dB

9
Morph
Applies to: LEAD Voice (Shift & Gender),
MIDI Voice (Mode & Style)
“Morphing is a special effect in motion pictures and animations that changes (or morphs) one image or shape
into another through a seamless transition. Most often it is used to depict one person turning into another
through technological means or as part of a fantasy or surreal sequence.” (Wikipedia)
Perform-VE’s Morph effect does exactly this to your voice: you can morph your lead voice into a giant, a mouse,
or a spaced out alien (and beyond) using the Shift and Gender parameters, while also morphing your MIDI voices
into choirs of angels, robots, zombies or whatever you dream up using the Mode and Style parameters.
Morph Style
Morph Style sets the MIDI Voices to be either Notes Harmony Voices or Synth Vocoder Voices. There are two
styles of Notes Harmony (Natural or Instrumental), and eight different Synth Vocoder styles to choose from.
Notes
Notes harmony voices are created from either your own voice, or a VSS Sample that you create with Perform-
VE’s innovative new Vocal Sampling Synthesis technology (covered later in this manual).
Formants are the unique resonant frequencies that give your voice its characteristic sound. When set to Natural
operation, the Notes harmony voices will retain the formant characteristics of your lead vocal. When set to
Instrumental, the voices will have their formant characteristics expanded or compressed depending on the
actual MIDI notes you play, making for tonal transformations that are striking, unexpected and possibly unreal
sounding when compared to the original. Try it and hear for yourself!
Notes Natural is the default mode for Perform-VE’s MIDI Voices. As long as MORPH and SAMPLE are turned off,
you will hear natural shifted harmony voices whenever you vocalize and send MIDI Notes to Perform-VE.
When MORPH is turned on, the MIDI Voice mode changes to reflect the MORPH Style – you can keep the MIDI
Voices Natural, make them Instrumental, or replace them with Synth Vocoder voices as you see fit.

10
Synth Vocoder
Perform-VE has a dual oscillator synth vocoder hidden inside. When Synth Vocoder styles are chosen, the
synthesizer will generate up to eight articulated synth voices to render the MIDI notes you play, and will also
generate a ninth Lead synth voice that follows the pitch of your voice.
The graphic above assumes a sample hasn’t been recorded. In this case, your Lead vocal gets a dedicated synth
voice and also acts as the modulator (shaping signal) for the Vocoder.
Enabling the SAMPLE button changes the way the Vocoder operates:
We’ll cover the SAMPLE features in detail later on. For now it’s enough to know that when the SAMPLE button is
green, the recorded sample acts as the modulator of up to 8 synthesizer voices, and your lead Vocal passes
through to the rest of the effects aboard Perform-VE.

11
Synth Vocoder Styles
Each one of the Synth Vocoder styles is actually a synthesizer preset (or patch), named accordingly:
Morph Mode
Morph Mode controls the Mono/Poly setting of the Notes, Vocoder and Sample MIDI voices.
Green LED selections set the MIDI voices to Poly mode, and adjust their release time (how long voices will take
to fade out after you release their controlling key). Bear in mind you will need to keep singing (play a long
enough sample) after the note release to hear the fade out.
Red LED selections set the MIDI Voices to Mono mode and adjust the portamento time from 0 to long.
Portamento time is how long it takes to glide from one note’s pitch to the next.

12
Morph Shift
Morph Shift pitch shifts your lead voice up or down by a set number of semitones. (+/- 12).
NOTE: If you control Morph Shift via MIDI Continuous Controller (CC) messages, the range is -36 to +36
semitones for even more extreme effects and automated sweeps.
Morph Gender
Morph Gender expands and compresses the formant signature of your voice to make it sound more male
(negative values) or female (positive values).

13
HardTune
Applies to: LEAD Voice
HardTune provides pitch correction that varies from subtle all the way up to T-Pain™ style tuning. Generally
speaking, pitch correction alters your Lead Vocal pitch to fit within a selected Key and Scale.
If all you care about is keeping your voice within
the defined black and white notes on the piano
keyboard, select the Chromatic scale, which is the
same for all keys.
On the other hand, if your song is in the key of C,
you’d likely get more musically pleasing results by
selecting the C Pop Major scale.
This scale is the C-Major scale (all white keys)
with an added dominant 7th for the blues-
influenced variations common in pop music.
When transposed to other keys, the Pop Major
scale can definitely look unusual. Here it is in the
key of C#, just one semitone up from C.
When using the Pop Major Scale, Perform-VE should be set to the correct key for your composition. You can set
this manually, or you can set the key to NaturalPlay to have Perform-VE automatically set the correction key
based on the chords it detects in the incoming MIDI or audio (Aux input).

14
HardTune Key
HardTune Key selects NaturalPlay Pop Major Scale, Pop Major Scale in all 12 keys, or Chromatic scale.
HardTune Amount
HardTune Amount changes the amount of pitch correction
applied to your lead vocal. Higher amounts mean more
T-Pain™ for you.
Range: Natural to Slammed!

15
XFX
XFX stands for ‘EXTREME EFFECTS’… it lives up to the name, as we’ll now explain.
Applies to: Lead Vocal
MIDI Voices
XFX Style
There are seven different XFX styles. You can choose between a Stutter effect, Chopper effect, Ring Modulation,
Flanging and even a SideChain Pumping Compressor. Each XFX Style has two dedicated mod parameters that
you can apply to tailor the XFX in question to suit your current inspiration.
XFX Style: Stutter
Stutter is an extreme effect that chops incoming audio into smaller time
divisions and quickly repeats those divisions, resulting in a stuttering
sound. At the largest time divisions you’ll hear the audio as rhythmic
repeats, while at the smallest time divisions, the audio cycles so quickly
that it produces a different pitched tone (or buzz) for each division.
Stutter will armed for sampling your Lead Vocal as soon as you select the
Style. Just vocalize and stuttering will begin!
Stutter Mod 1: Division
Stutter Mod 1 controls the size of the stutter division in real time. The Quarter Note division is indicated by a
white LED, while all other divisions are light blue LEDs.
Stutter Mod 2: Level
Stutter Mod 2 changes the level of the stutter
audio, relative to your Lead Vocal.
On the ring, Level is indicated from one up to all
LEDs lit up in Cyan.
Range: Off, -10 to 0 dB
Pausing Stutter
You can put the Stutter effect on hold at any time by turning the XFX toggle off. Your stutter sample won’t be
lost while the effect is turned off.

16
Recording a new Stutter Sample
To record a new stutter sample, simply select a different XFX Style and then step back to Stutter. Recording will
be armed for your new stutter sample.
For even faster re-recording of the stutter sample, double-click the style corner
button and this will instantly clear the sample and arm the Stutter effect to record a
new sample.
XFX Style: Chopper
There are two Chopper styles: Mono Chopper and
Stereo Chopper. At full depth, Mono will gate the
level of the audio, while Stereo will alternate
(ping-pong) the audio between Perform-VE’s left
and right stereo outputs. Both Chopper styles are
beat-synchronized, of course!
Chopper Mod 1: Division
Chopper Mod 1 controls the size of the Chopper’s rhythmic division in real time.
Chopper Mod 2: Depth
Chopper Mod 2 changes the depth of the volume
modulation (gating), relative to your Lead Vocal.
On the ring, Level is indicated from one up to all
LEDs lit up in Yellow.
Range: 0 to 100%

17
XFX Style: Ring Mod
The Ring Modulator multiplies your lead vocal with an internally
generated sine wave to create a classic ‘Dalek from Doctor Who’ sound.
At full Ring Mod depth, you’ll be ready to visit planet Skaro, but subtle
amounts can also work wonders on a vocoder voice to bring out an old-
school Electric Cylon Orchestra sound for a retro sci-fi clip or two.
Robots and aliens aside, a bit of Ring Mod will give any signal a gritty
electronic characteristic that follows the pitch or melody of the input
signal. It’s very useful!
Ring Mod, Mod 1: Frequency
Ring Mod, Mod 1 controls the frequency (pitch) of the
modulating sine wave. Sweep it across its range to
apply a vintage radio tuning sound on your fixed pitch
signal, or keep the frequency fixed while singing a
melody to hear that 1950’s UFO/Raygun sound.
Range: 30 to 1000 Hz
Ring Mod, Mod 2: Level
Ring Mod, Mod 2 controls the level of the
ring-modulated signal relative to the input audio signal.
Range: 0 to 100%
XFX Style: Flange
Flanging is an audio effect produced by mixing
two identical signals together, with one signal
delayed by a small and gradually changing
amount.
Part of the flanged signal is fed back to the input,
producing a resonance effect which further
enhances the intensity of the sound.
Flange 1 is a Negative Flange: the phase of the fed-back signal is inverted (made negative), producing a striking
alternative to the classic sound of Flange 2 (which is a Positive Flange).
Flange, Mod 1: Speed
Flange Mod 1 controls the speed of the gradually
changing delay time. You can take the flanging from a
subtle slow ‘Jet Plane’ sweep variation all the way up to
an extreme ‘wowing’ effect.
Range: 0 to 100%

18
Flange, Mod 2: Depth
Flange Mod 2 controls the depth of the effect, from
subtle to very obvious.
Range: 0 to 100%
XFX Style: SideChain Pumping
The SideChain Pumping Compressor is meant to be used with the
LOOPER’s built in drum sequencer. When you are playing a beat, the
SideChain Compressor will momentarily throttle back (compress) the
volume of your Lead, MIDI and audio loop mix whenever the drums hit a
certain threshold volume: This ensures your drums will always stand out in
the mix. This effect is also called ‘SideChain Pumping’.
SideChain Pumping, Mod 1: Compressor Threshold
The SideChain Compressor reduces the level of the
non-drums audio signal if the drum mix level exceeds a
certain ‘trigger’ threshold value.
SideChain Pumping Mod 1 controls this compressor
threshold: Lower threshold values mean a larger
portion of the non-drums audio signal is compressed.
Range: -60dB to 0dB
SideChain Pumping, Mod 2: Compressor Release Time
SideChain Pumping Mod 2 controls the Compressor
Release Time. It lets you define how quickly the
compressor acts on an incoming audio signal. When the
input level falls below the compressor threshold, there
is a delay between the compressor release and the
input signal's return to full strength. This delay is the
Release Time, and its amount is indicated on the LED
Ring.
Range: 1 ms to 3 seconds

19
Echo
Applies to: LEAD Vocal
MIDI Voices
Echo is a combined Delay and Reverb processor. Echo effects repeat your voice back to you in various ways and
amounts, simulating the effect shouting into a mountain range (delay) or very large space (reverb). With Echo
turned on, you’ll get delay and reverb combined as you like them.
Echo Style
Echo Style changes the Reverb settings. The LEDs indicators are colored by type - there are two natural reverbs
(Hall & Arena) and two electromechanical reverbs (Spring & Plate) to choose from.
Echo Reverb
Echo Reverb is a master parameter that simultaneously
edits the reverb’s decay time and output level. Greater
amounts will expand the perceived size of your
reverberation, so you can make even a small plate
reverb sound gigantic if you want.
Range: 0 to 100%

20
Echo Div
Echo Division controls both the Delay’s rhythmic division and its type. Blue LED selections are Ping-Pong delays
in which echoes ‘bounce’ between left and right in the stereo field, while Green LED selections are delays in
which echoes are heard on both sides of the stereo field. The Red LED selection is a short single-repeat echo
called a Slapback delay, useful for dialing in a retro 50’s pop song vibe.
NOTE: As with other effect division parameters, a White LED indicates a straight quarter note division.
Echo Delay
Echo Delay is a master parameter that simultaneously
edits the delay’s feedback and output level. Greater
amounts will expand the volume and increase the
number of delay echoes that you hear. At 100% the
delay will feedback into echoes that never stop!
Range: 0 to 100%
