Whenever you download a new version, you don’t need to uninstall the previous version beforehand, and you can just repeat the installer process.

On Windows, you can uninstall the program by going to Control Panel  Programs  Uninstall a program.

Authorization

The plug-in runs in demo mode until you authorize it with a license file.
In demo mode, presets cannot be saved nor recalled, and a nag screen appears now and then.

When you have purchased a license, please go to your user account to download the corresponding license file, then save it in a safe place on your computer.

Launch your favorite host and add an instance of the plug-in, then click on the setup button located at the right of the toolbar.

Click on the Register button at the bottom-left of the setup screen, then select your license file in the file dialog, and finally press OK to load the license file.

You can unregister the software at any time by clicking the Unregister button.

The license grants you the rights to use the plug-in on one computer at a time. You can therefore authorize both your laptop and desktop computers, as long as you are the sole user.

This applies to individuals only. Companies and institutions should purchase one license per seat.

User interface basics

Main interface

Changing parameters

Rotary controls use the so-called linear mode by default, meaning that they respond to up, down, left and right movements. If your VST2 / VST3 host has a rotary mode setting, this will be used instead.

All controls except switches and buttons also respond to mouse wheel movements, which you might find to be faster and easier than clicking with the mouse.
When you hover over a control or change its value, its label will turn into a numeric display, revealing its current value and its corresponding unit of measurement (Hz, dB, etc.).

Modifier keys

The table below lists available modifier keys. The tooltip area also displays the modifier keys for the host the plug-in is inserted in.

Controls also respond to the arrow keys. Press or to increase the value, or to decrease it. Use the modifier keys above to make more precise adjustments.

Tooltips

Tooltips appear automatically when you hover over an active section of the user interface. They are displayed as a transparent overlay at the bottom of the plug-in user interface.

Tooltip display area
Tooltips can be disabled by clicking the info toggle button in the settings dialog, once you know your way around the interface and these become distracting.

For VST3 hosts, use Alt ⌥+Right-click to access the built-in context menu instead of the host context menu

Section context menus

The note, octave, pan, level and detune labels located to the right of the corresponding resonator parameters also have specific context menus to apply various useful batch operations.

Host context menu (VST3 / AAX)

The VST3 and AAX plug-in format specifications add some handy functions to access relevant host functions directly from the plug-in interface. These extensions do require support on the host side, but as of today most recent versions of mainstream hosts have implemented them.

VST3 format

The VST3 host context menu generally incorporates shortcuts to show the automation track for the relevant parameter, as pictured in the next screen.

Cubase and Nuendo also feature specific Quick Controls, which is a very nice feature which allows you to easily map your favorite MIDI controller to up to 8 plug-in parameters. The advantage is that you only need to set-up your MIDI controller once in Devices  Device Setup …​  VST Quick Controls. After this just right-click on a parameter control to associate it with your MIDI controller, and you’re done.

Please consult the relevant host documentation for more details.

Detail

Click the detail button to toggle between full graphics detail and flat mode. Flat mode reduces all visual candy such as shadows and lighting to a minimum, which can help with less powerful GPU’s such as those integrated in lower-end laptops.

Info

Click the info button to toggle tooltip display on and off.


Resonators

The central area of the user interface is dedicated to the 12 resonators, which are the heart of the sound engine. The tuning of the resonators can be set individually as well globally. While this panel might seem a little crowded and daunting at first, it helps to think of it as a kind of large-scale console, where every resonator is a vertical channel strip with an identical set of controls.

Resonators panel

A note about tuning

As Superchord generally produces sounds with an identifiable pitch, it is very important to match the pitches to something that fits with the key of your song. When you feed input content that has no identifiable pitch, such as percussion, the resonator can be tuned to your liking. However, when the input audio is pitched, be it a guitar lick, singing voice lick or else, you will find that the resonators need to be tuned to the key and scale of the phrase, if you want to avoid unpleasant pitch frictions. In effect, the resonators should in effect be treated as any other pitched instrument: they sound definitely better in tune !

Master controls

The following controls, located to the right of the resonators, affect all resonators simultaneously.

Transpose

Click one of these four buttons to shift the notes / octaves of all resonators up or down.

Gain

Adjusts master resonator output gain, after summation of all resonator output signals.

Tuning

Affects master resonator tuning, relative to A4. The default value is standard 440Hz concert pitch.

Tuning range

Click the button below the tuning knob to switch to an extended range of A3-A5 (220-880Hz). This can be used to create dramatic whammy-bar style effects, or to switch between two different tunings on the fly.

Controls

Each resonator has a set of the following individual controls, from top to bottom.

Note

Sets the base note of the resonator.
Click on the right portion of the control to increment the note, on the left to decrement it, or use the mouse wheel to change the note quicker. Right-click on the control to display a context menu where you can select a note directly by name.

Octave

Sets the octave of the resonator.

Level meter

This small LED gives an indication of the output level of the corresponding resonator.

Pan

Sets the position of the resonator output in the stereo field.

Level

Sets the level of the resonator output.

Detune

Sets the fine tuning of the resonator pitch, in cents, relative to its base note.

Solo

Puts the resonator in solo mode, to hear it temporarily in isolation.

Mute

Mutes the resonator, when you don’t need to use all resonators.

Mute has priority over Solo.
Interesting unison effects can be achieved by setting two or more resonators to the same pitch (note and octave), and by detuning each of them slightly.
You can also spread the resonators over the stereo field using different pan settings to achieve a wider, bigger, fatter sound. Use the tilt and randomize context menu functions to do this with a single click.

Global context menus

Right-click on any of the note, octave, pan, level or detune labels, located to the left side of the resonators to bring up a series of context menus that affect all resonators globally.

Context menu
Name Description

Reset

Resets every corresponding parameter back to its default value.

Randomize

Sets every corresponding parameter to a random value.

Tilt

Nudges every corresponding parameter by a small random amount, from its current value. This is useful to quickly obtain a variation of the current settings.

Unison

Sets all notes to that of the first resonator.

Single

Sets all octaves to that of the first resonator.

Chromatic

Sets the resonator notes as a series of chromatic intervals, starting from the first note.

Intervals

Sets resonator notes to the specified interval, repeated as necessary.

Octaves

Spreads resonator octaves as a series, repeated as necessary.

Other

Solo/mute defeat

The two solo/mute buttons located to the right of the resonator solo/mute buttons temporarily defeat the individual resonator solo/mute’s states, like on a mixing console.
Ctl+Click on one of those buttons to set/clear all solo/mute states in one go.

Resonator delay

Located above solo/mute defeat controls is a small button to switches between resonator detune (default) and delay modes. When engaged, resonator detune controls are replaced by individual delay controls. Delaying resonator by different amounts can be interesting to add an extra sense of depth and space.

Model

Overview

Each resonator models a damped vibrating string moving in two so-called separate planes of polarization.
The more damping is applied to a string, the quicker it loses energy at its termination points (bridge and nut), and the quicker sound fades out.

The model parameters affect the global character of the sound produced by the resonators, as explained in more detail in the following sections.

As you will probably notice, the number of possible combinations is quite large, so it will take some time to explore them all.
We therefore recommend that you familiarize yourself with Superchord’s possibilities by listening to the various factory presets, using those as a starting point to tweak the model parameters and understand their respective effect on the sound.

Base controls

Resonator model panel

Damping

This parameter affects the overall damping factor of the resonators.
A high damping value prevents most resonance from occurring, whereas a lower value will make notes ring longer, up to the point of infinite sustain. This is analogous to the decay time control found in reverb units, except it is inverted.

Shimmer

Shimmer controls how long upper harmonics ring, relative to the fundamental. This parameter models a phenomenon found in most acoustic instruments, where harmonics decay faster than the fundamental.
A low shimmer value makes the higher harmonics die out very quickly, not unlike a guitar player using palm muting. On the contrary, a high shimmer value will produce a bright scintillating sound.

Darkness

Darkness is essentially a low-pass filter which gradually muffles the sound. This can be put too good effect to tame any excessive harshness.

Mistune

Mistune controls the relative tuning between horizontal and vertical polarizations, in cents.
An ideal string would have both polarizations perfectly in tune, whereas in real life, depending on the construction of the instrument, this will not hold anymore.
Small values lead to a kind of double-string, chorus-type effect. Higher values will give a sound reminiscent of an old honky-tonk piano or a guitar fitted with washed-out strings.

Feedback

Feedback corresponds to acoustic coupling between horizontal and vertical polarizations. This subtly increases the body and fullness of the sound, and also makes notes ring a bit longer.

Coupling

Coupling refers to the acoustic coupling between strings, or the overall sympathetic resonance.
In the real world, acoustic vibrations recirculate from a string to its neighbors, which can even lead to acoustic feedback, a.k.a Larsen effect when amplified.

To avoid excessive feedback, prevent damage to your speakers and ears, and model real-world behavior, this feedback is limited by a non-linear element, which emulates things such as amplifier distortion and clipping. This feature can be put to interesting effect and simulate an all-out, everything dialed to 11' guitar amplifier, as demonstrated in the Super Destroyer preset.

The little LED below the dial gives a real-time indication of the overall sympathetic resonance level.

Advanced controls

Click the button located below the Darkness control to reveal the advanced model control panel. These controls generally have a more subtle effect on the sound, and are intended for advanced users interested in fine-tuning and special effects.

Resonator advanced model panel

Tracking

When the input audio material contains a lot of low-frequency content, low-pitched strings and harmonics will tend to sound relatively louder than others.
The tracking parameter can remedy this by carving out some of this low-frequency content, using a high-pass filter with a cutoff frequency that tracks resonator pitch, to maintain an overall timbral balance.

Pluck pos.

Pluck position simulates how plucking a string at various positions affects the sound.
This has a direct effect on which harmonics are excited: for example, plucking exactly at the center leads to even harmonics, giving a characteristic, tube-like hollow sound. Values towards zero correspond to the bridge, whilst one corresponds to the neck.

H.V in

This parameter determines the horizontal to vertical polarization input mix ratio.

H.V mix

This parameter determines the horizontal to vertical polarization output mix ratio.

Damp H.V

This parameter controls the damping of the vertical polarization with respect to the horizontal polarization. In effect, setting this to a value to something lower than 100% will give a more complex decay envelope, comprising two stages.

Buzz

Buzz mimics the characteristic buzzing that occurs in instruments with non-rigid string attachments, such as the Indian sitar.

Mixer section

Mixer section

The big mix knob controls the dry / wet amount, and the reactive meters monitor output levels.
When using little resonator damping and or high Q filter values, it’s worth paying attention to the output levels for any overloads, and adjust the master gain knob accordingly.

The two small round buttons below the mix knob there allow listening to the dry (input, right) or wet (effect, left) signal in isolation respectively.

LFO

Usage

The LFO (Low Frequency Oscillator) module modulates target parameters at a periodic rate.

LFO module

Controls

LFO

Toggles the LFO module on and off.

Sync

This button toggles between two timebase modes:

  • Internal: free running

  • External: synchronized to host tempo

The LED below the sync button pulses in sync with the LFO modulation signal. The oscilloscope shows a graph of the recent LFO history, to help you visualize what you hear.

Rate

Rate controls the LFO speed.
Depending on the sync setting above, its value is expressed in

  • Hertz, with internal sync

  • Musical time sub-division, in musical fractions of the host tempo (BPM)

Shape

The LFO offers the following choice of several classic as well as more esoteric waveforms:

sin

sinewave

tri

triangular

saw

ramp, ascending

saw -

ramp, descending

sqr

square wave

s|h

sample and hold: jumps to a random value on every cycle

s|h 2

variant of above that jumps a small random amount every sample

chaos

chaotic pattern, with a certain regularity

chao5

another chaotic pattern

chua

chaotic waveform based on the Chua oscillator

shot

emits spikes a random intervals

Target

Controls which parameter is modulated by the LFO, i.e. its destination.

  • freq modulates the cutoff frequency of the filter

  • pitch modulates the overall pitch of the resonators

  • gain modulates master gain for tremolo-style effects

Mod

Determines the amount of modulation applied to the target.

Direction

Determines how the LFO modulates the target parameter value

  • both modulates up and down, symmetrically around current value

  • up only increases the value

  • down only decreases the value

Envelope Follower

Usage

The envelope follower modulates the target parameter with the variations in amplitude of the incoming audio, to create various dynamic effects.

EF module

Controls

ENV

Clicking on the ENV button toggles the envelope follower on and off.

Target

This parameter sets the modulation destination, as in the LFO module.
When the EF and LFO targets are the same, their signals are combined.

Set target to gain to modulate output volume and achieve a gating / ducking effect. When set to freq, the filter cutoff frequency will be modulated by the incoming audio, as in an auto-wah pedal. You can also set this to pitch to mimic note bending, preferably using a small modulation amount, to avoid seasickness.

The little LED below the Target control displays the current output level of the envelope follower.

Attack

Controls the attack time of the detector, in seconds.
A short attack will make the envelope follow input volume variations almost instantaneously, while larger values lead to a more pronounced swell effect.

Release

Controls the release time of the detector, in seconds.
A short release will make the envelope decrease rapidly to zero when input volume drops. Decreasing this value will make the envelope hold longer following a short attack.

Mod

This controls the modulation amount. Increase towards 100% to get a more pronounced effect.
A ducking effect can be achieved by setting it to a negative value and using gain as the target. The sound will then be cut when the input gets loud, and come back in quieter passages.

Filter

Usage

The filter module is based on an analogue-modelled design, and can be modulated at audio rate.
It can be used to shape the tonal content of the effect, or as a modulation target to achieve more drastic effects. Try mapping the filter cutoff frequency and Q to hardware controls to really play the filter live.

Filter section

Controls

FILT

Toggles the filter section on and off.

Pre/Post

Switches between the two possible filter positions.
By default, the filter acts on the output of the resonators (post). This setting gives the most dramatic results, especially when doing filter sweeps. Try sweeping the filter with a moderate Q and listen how the resonator harmonics start to 'sing'. The pre position puts the filter before the resonators, which allows to tailor the frequency content of the incoming audio, and therefore control which harmonics are being excited.

Frequency

This control adjusts the filter’s cutoff frequency, in Hz.

Q

Determines the quality factor, or resonance of the filter.
Low Q values give a mostly smooth curve, while higher Q values create a bump around the cutoff frequency. Going all the way up to 1 will take the filter into self-oscillation territory.

Mode

The mode parameter determines the shape of the filter curve.

  • LP (low pass): progressively removes content above the cutoff frequency

  • BP (band pass): removes content below and above the cutoff frequency

  • HP (high pass): removes content below the cutoff frequency

Fat

The filter module can be switched between two different models. The default setting (off) should cover most needs, whilst enabling fat mode will imprint a subtly different character to the filter’s sound.

Saturation

Usage

The saturation module lets you add effects ranging from light tube-like warmth to heavy amplifier crunch and growl.

Saturation module

Controls

SAT

Toggles the saturation module on and off.

Reso/Post

When set to reso, the saturation module acts on the output of each resonator individually.
When set to post, saturation is applied to the summed output of all resonators.

You will notice that the two settings often produce notably different results. post mode simulates what happens when you feed a guitar’s pickup output to a distortion pedal and/or amplifier, creating complex harmonics, inter-modulation distortion, etc.

Drive

Controls the input gain of the saturation element, in dB.
Low values produce mild tube-like warmth, mid values will lean towards crunch and grit, whilst extreme values give fuzz-like tones. Output gain is compensated internally to maintain a constant perceived loudness.

Dynamics

Usage

In the real world, there is a certain limit to the amplitude of a string’s vibration. This is because a real string’s behavior departs from an ideal mass-spring, so it can only store a limited amount of energy before breaking. If you ever played guitar, you have most probably experienced this at least once by pulling or picking too hard.

The dynamics module models this non-linear aspect of a string, and also helps prevent the audio output from blowing up, for example at very small damping values causing infinite resonance.

You can think of this module as a special kind of compression device, although it acts on the total internal energy of each resonator, and not just on the output signal.

Dynamics module

The dynamics module is always on to protect your ears and speakers. At its default settings, the limiter is completely transparent with no gain reduction applied.
The small bargraph below the [DYN] label shows the amount of limiting applied.

Controls

Attack

Controls the delay before the energy limiter kicks in.
Setting this value to a few milliseconds will make the limiting act almost instantaneously. A value in the order of several hundred milliseconds will let more of the peaks come through.

Release

Controls the time for the energy limiter to fall back to zero.

Ratio

Controls the slope of the limiter. The resulting dynamic range decreases with increasing ratio.

Threshold

Sets the value over which the limiter kicks in, in dB.

Instrument mode

Overview

Instrument mode is enabled by clicking the FX toggle button, after which it will display INS.
In this mode the resonators are now controlled by incoming MIDI messages, which allows you to play chords and melodies, with the incoming audio still driving the resonators.
When you press a key, the next first available resonator is 'activated' and its pitch set to that of the incoming MIDI note. Upon releasing the key, the envelope enters its release phase and the resonator is subsequently 'deactivated'.

Instrument mode

In instrument mode, input audio is still needed to drive the resonators, so you’ll still get silence out if you feed silence in, as in FX mode.

Host Setup

Just as in FX mode, the plug-in should be inserted on the audio track you wish to process. In addition, you will need to create a MIDI track and route it’s output to Superchord’s MIDI input.
Please consult the documentation of your host for specific details on how to do this.

Logic Pro X (macOS only)

Logic Pro requires a somewhat specific setup. Please follow these steps:

  1. Click on Track  New Software Instrument Track to create a new software instrument track

  2. Go to the mixer and click on Input  Instrument in the newly created track

  3. Select AU MIDI-controlled Effects  lmdsp  Superchord in the drop-down menu

  4. Open Superchord’s editor window and select the audio track to be processed in the Side Chain menu

Logic Pro X mixer routing

Controls

Resonators

The instrument engine assigns incoming MIDI notes to free resonator voices.
Currently playing resonators are displayed at the top, with their corresponding note and level. While most settings are shared with regular FX mode, each resonator output is modulated by a VCA envelope generator, which shapes the evolution of its volume in time.

Envelope

The envelope is a classic ADSR generator as found on many synthesizers. The graph on the right side displays the volume curve applied to resonator voices.

Attack

Controls the rise time of the volume envelope, in seconds. A longer value here will lead to a gradual volume swell, which is suitable for pads and similar sounds.

Decay

Controls the decay time of the volume envelope, in seconds.

Sustain

Controls the sustain level of the volume envelope.

Release

Controls the release time of the volume envelope. This is the time for the envelope to fall back to zero after the key has been released.

Range

Controls the velocity dynamic range. Setting this to zero will lead to notes all having the same volume, irrespective of the incoming MIDI note velocity, as it happens in some organs.

Level

Controls the velocity to volume level scaling. Adjust this to a suitable value depending on your playing style.

Context menu

Right-click inside the envelope module panel to bring up a context menu with pre-defined envelope shapes.

Envelope presets context menu

Controllers

Pitch wheel

You can use the MIDI pitch wheel message to perform pitch bending and vibrato effects.

Playing tips

Try playing chord progressions on a keyboard or entering chords in your DAW’s MIDI editor, using rhythmic material as the incoming audio source. Listen how the rhythmic part imparts complex modulations onto the chords. Adjust damping to a medium value so the rhythmic changes can be heard, and play with the envelope settings to change from pad type to percussive sounds.

For a richer sound, duplicate the chords at various octaves above and below.

Take advantage of any included MIDI effects included with your DAW to quickly generate chord progressions. If you’re using Cubase, give the Chord Track and Chord Pads (since version 8) a try.

NKS

Superchord supports the Native Kontrol Standard (NKS) for seamless integration with NI’s range Komplete Kontrol keyboards and Maschine hardware.
All presets are tagged for quick filtering and auditioning, and most parameters are mapped to a physical knob, arranged as logical sections distributed over 9 pages. The first page is optimized for live performance, while the remaining are more suited towards experimentation and fine tuning.
