Introduction
Bass Slapper is a sample-based virtual instrument that enables you to play
a bass guitar on a MIDI keyboard. It provides a uniquely realistic bass sound
by playing notes the way a seasoned bass player would play them—not just the
notes, but also the correct position on the fretboard with the corresponding
articulation preference. This produces naturalsounding samples without the
need for manual layer selections. There’s an extensive library of high-
resolution samples, chosen and recorded carefully in a way that best captures
the essence and sound signature of the slap bass technique.
Bass Slapper is powered by the Waves Sampler Engine (WSE), a state-of-the-art
multi-sample engine designed to deliver solid, high-quality sampler
performance. It provides a multitude of sound processing options, which range
from shaping the core sample tone to selecting among modulation and spatial
effects that are carefully designed for Bass Slapper.
Acknowledgment
All samples were recorded by Or Lubianiker, a highly-regarded live and session
bass player. The samples were recorded with Or’s signature sound in mind,
using his choice of bass, strings, and preamps. His profound technical
understanding Jof slap technique formed the base for the legato and
articulation systems, and shaped the sound of the sample library.
What is Slap Bass?
Slap Bass, or “Slapping,” is a bass-playing technique that focuses on the
percussive nature of the sounds generated by a string rebounding against the
frets. Bassists use the side of the thumb to strike the strings and their
index or middle fingers to pull the strings and bounce them against the frets,
resulting in a sharp attack followed by a quick decay. This, in some ways,
resembles both bass drum and snare sounds. Slapping was made famous in the 70s
funk, disco, and pop scenes by accomplished bassists such as Larry Graham,
Louis Johnson, and Bootsy Collins.
Over the years, Slapping has become a rich discipline on its own right and a
distinct sound that accompanies every genre, from timeless pop songs to jazz
and fusion compositions.
The Sample Library
The sample library contains over 3700 samples, all of which are designed to
give you the most extensive and rich slap vocabulary possible.
The library contains these sample categories:
- Slap samples
- Pull with the 1st and 2nd fingers samples
- Hammer On and Pull Off (legato) samples
- Percussive samples
- Release samples
- Slides and special effects samples
All of these were recorded with several velocity layers and round robin
samples.
There are two identical Bass Slapper sample libraries: Standard and High
Definition. The main difference is the quality, and therefore the size, of the
files. Let’s say you’re creating your sound at home on a laptop—where storage
may be limited—but you will mix on a large rig in a studio. You may choose to
use the SD library at home and then load the HD samples when you mix. All
programming is maintained when changing between libraries.
Components
Bass Slapper is a stereo-only virtual instrument plugin. It appears under the
related selection menus for virtual instruments under all supported DAW host
applications. Bass Slapper also works as a standalone application, using ASIO
(Windows) or Core Audio (Mac) drivers to play through your audio device. Bass
Slapper receives MIDI data to trigger notes and control changes.
In addition to the plugin, there is a free-standing Bass Slapper application.
Functional Block/Flow Diagram
Getting Started
Bass Slapper is easy to use, and you can undoubtedly learn to play it without our help. There are many different ways to use it and you will quickly come up with a way that’s perfect for you. But while you’re getting started, we suggest you follow the work sequence we describe below. Once you’re comfortable using Bass Slapper, arrange your workflow any way you like.
By default, Bass Slapper opens with the FX section hidden. Click on the + (plus) button on the bottom left to reveal the FX processors.
- Insert the Bass Slapper plugin on an instrument track in your DAW, or launch the standalone application. The plugin will load its default preset and will be ready for you to use.
- Play a few notes and explore the basic tone controls, which are located on the body of the bass.
- Refine the tone and timbre of the sound with the Fretboard Position control. This moves the playing position up and down the fretboard.
- Use the FX sections to sculpt your bass sound. Click on the + (plus) beneath the fretboard to reveal these pedalboard processors.
- Set the Velocity Curve control to adjust your keyboard, in order to get the feel you like. This control is in the MIDI section. Once you’re happy with the keyboard touch, you can uncheck the VEL (velocity) box in the top bar. This prevents the velocity setting from changing when a preset is loaded.
Navigating the Presets
Bass Slapper presets are managed with the WaveSystem Toolbar at the top of the
window. Use the Next/Previous preset arrows on the Toolbar to scroll through
presets. Click the Presets button to see all presets. To learn more, click
the icon at the upper-right corner of the window and open the WaveSystem
Guide.
Selecting the Samples Folder
When you first launch the standalone application or instantiate the plugin,
you will likely see a prompt, “Please locate your Waves Instrument’s Samples
Library folder.” Navigate to the folder that holds your sample library and
click OK. This path will be saved with the plugin preferences. Information
about the samples folder is shown in the WaveSystem toolbar. To select a
different sample folder, click on the Samples Library bar and navigate to the
desired folder. The folder must contain valid Waves sampled instrument files
with the WSF resource, otherwise the OK button will be grayed out. This new
selection replaces the existing folder location preference.

- Tone Function Controls
- EQ and Levels Controls
- Power Controls
- Fretboard Position Selector
- Active Position Range

- FX Pre
- FX Post
Tone Section
The tone section contains the controls that affect basic sample sound and
articulation. All controls are on the body of the bass.
Slap/Pull
This control is depicted as a slider beneath the strings on the body of the
bass. It controls which articulation (Slap or Pull) will play as default
across a selected range of strings. For example, when the D String is chosen,
all samples played on the D and G strings will be “Pull” samples, while the
rest will be “Slap” samples. We recommend that you set this slider on the 4th
string (D) as your initial setting and experiment from there.
Vintage/Modern
The effect of this control ranges from a warm vintage tone with a rich low end
(knob turned all the way to the left) to a detailed, punchy sound fit for a
modern production (knob turned all the way to the right). This is an easy way
to dial in a suitable basic tone for the samples that are going into the
processing chain.
Low Boost
The Low Boost knob enhances the bass and sub frequencies of the sample
without sending them into the processing chain. This results in a consistent
and coherent low-end response, even with presets that drastically change the
sound of the sample—such as using multiple stomps and effects
Sub Octave
A sub-octave synth layer that tracks and changes in tone according to the
range. This layer is sent to the processing chain and is affected by all of
the modulation and effects in the instrument. It can enrich any bass line and
it offers many creative sound design possibilities.
Release
Release samples are the artifacts and mechanical noises that a real bass
produces when the musician either stops a note or moves to a new one. These
samples are triggered at the very end of every sample. Each note has a unique
release sample, which has been sampled at every velocity and that will be
played upon releasing its key.
EQ Controls
The EQ section features a four-band EQ with Bass, Low Mid, High Mid, and
Treble boost/cut controls. In the processing chain, the EQ is positioned
between the “Stomps” and “Effects” sections of the pedalboard.
The equalizer is an integral part of the amp; it is bypassed when the amp is
switched off.
Levels Controls
The Levels section contains four knobs, each of which controls a different
aspect of the instrument’s output sound.
Direct
This controls the level of the direct sound—the sample played through the
processing chain without amp simulation.
Amp
This is the level of amp simulation. This signal path goes through the same
process as the Direct signal, but ends in an amp simulation module that shapes
the tone as would an 8×10 cabinet. The Amp simulation path is parallel to and
independent of the DI level. It has different frequency response and
compression than does the Direct signal.
Use the Amp Type drop-down menu to choose between six different bass amp IRs
to modify the size and warmth of your bass tone. We recommended that you begin
by choosing either the amp or the direct as the main tone, and then slowly
mixing between the two to find the right balance.
Turning off the amp power bypasses the Direct and Amp controls and disables
the Amp Type drop-down menu.
Limiter
The Limiter knob controls the threshold of the output limiter. Higher settings
yield more gain reduction.
Output
This controls the output level of the instrument.
Power Controls
The power section contains five toggle buttons that allow you to deactivate the Tone, Pre FX, Amp, Post FX, and Limiter sections separately. Deactivating modules decreases CPU load and may improve performance. This is particularly useful in CPU-heavy projects with lots of plugins: projects where every bit of power matters.
Fretboard and Position Controls
The Fretboard section features a 24-fret, 5-string bass guitar neck with a
position indicator (a 5-fret range, highlighted red) and note displays.
Playing a note triggers a visual indication on the fretboard that marks the
exact position of the sampled note. Clicking a string on any fret will show
the selected note.
Position Selector
There are eleven numbers above the fretboard; together these make up the
Position Selector. Each selection represents a five-fret range in which
selected notes will be played in a compliance with how a bass player actually
performs. Strings share some of the same notes. This selector gives the user a
way to explore the tonal variations that come from playing the same line
using different note positions and articulations.
The Position control also determines the polyphonic behavior of the instrument
across strings. Say, for example, you want to play two notes at the same time.
This may not be possible. Depending on the current position, both notes may
be on the same string. Move the position on the fretboard so that these notes
are played from different strings.
To ensure that the sampler triggers proper legato and articulation selections
that sound natural within a range, adjust the Position setting to a value that
associates with the pitch range of the notes being played. Experiment with
this control and listen to the multitude of tonal options it introduces to any
bass line. Different settings can result in drastically different sounding
lines.
Dead-notes Trigger
This button changes every note on the keyboard to a corresponding dead-note
sample, according to its location on the fretboard, and in compliance with the
articulation settings (Slap/Pull and Position settings). This is like a bass
player muting the strings with his left hand; a very common technique in
“Slapping.” This control is not automatable, but it is MIDI assignable.
Keyswitch Editor
Use the Keyswitch Editor to assign specific samples and articulation controls
to the keys of the lowest octave (C0–B0). These keys are not otherwise used,
so assignments do no not affect playing samples. To access the editor, click
on the Keyboard icon located just above the fretboard. The editor opens with
the factory setup.
To modify these settings, click the down arrow next to a note label, and then
choose an assignment from the dropdown menu. When using a keyswitch that’s
assigned to articulation controls, you should first hold the keyswitch, and
then play a note. Keyswitches that are assigned to samples function like all
other keys; they are sensitive to note velocity. For example, assigning the
“All Slap” articulation to the key A0 means that every note will play as a
“Slap,” as long as A0 is held.
MIDI Functions/Articulation Section
The MIDI Functions/Articulation Section contains controls that manage basic
functions: velocity behavior, round robin order, transposition, and sustain
pedal activation. Click on the + (plus) symbol to expose a section.
Round Robin Mode
Controls round robin playback order: forward, reverse, and random playback of
round robin samples. When the Round Robin Mode is switched off, the longest
available sample will always play.
Transpose
Adds pitch offset to the incoming MIDI notes in semitones from -24 to +24.
Velocity to Volume
Determines the extent to which velocity layers will differ in playback volume.
When this knob set to 0, all velocity layers will play at their original
levels. When set to 10, the velocity layers will vary drastically in volume.
Velocity Curve
The Velocity Curve control changes the curve of the velocity response from
logarithmic to exponential. Use it to adjust the feel of your MIDI keyboard.
Modulation
Modulation controls the depth and rate of pitch modulation. Higher Depth
settings result in a wider range of movement between pitch values below and
above the sample. The modulation rate determines how fast or slow it will
move between the values. Modulation depth is, by default, mapped to the
modulation wheel on the keyboard.
Sustain Pedal Button
The Sustain Pedal button activates/deactivates the sustain pedal. The Sustain
LED lights when the sustain pedal is in use.
Open Strings
The Open Strings section contains four toggle buttons that force the sampler
trigger to an open string sample as default when played at the corresponding
open string pitch (E1 A1 D2 G2), regardless of the Position setting. This
control was added to accommodate for playing a line against an open string the
same way many bass players would do if asked to play in one of the open string
keys (B E A D G). Prioritizing the open string sample makes sure that the open
string pitches are always heard at their best possible tone.
Legato Type
The Legato Type control enables control over triggering the legato samples.
Realistic
-
The instrument uses the Position settings to generate legato or non-legato samples, according to the context. For example, when playing a new note on the same string as the previous one, Bass Slapper will mute the played note, since on a real bass it is not possible to play two notes simultaneously on the same string.
Extended -
This mode allows you to trigger legato samples on the same string, beyond the fret range as determined by the position selector. This mode can enhance the legato system when playing phrases with extended legato ranges.
Force Legato -
While this mode is on, the sample engine will trigger legato samples, disregarding realistic limitations or particular strings. This allows the user to play continuous hammer on/pull off samples across strings in a way that’s not possible on a real bass guitar. This type of legato resembles the sound of a player constantly “tapping” the bass.
Always -
This mode will always trigger the legato samples, even when the notes played do not overlap. This mode will avoid triggering both slap and pull samples, making the overall sound of the instrument much softer.
Off (Polyphonic) -
Turning Legato Type off allows playing to every note with no legato rules whatsoever. This mode will essentially make the instrument polyphonic, with the ability to play all notes at the same time (even on the same string). This produces a synth-like feel.
Position
The Position switch sets the playing position on the fretboard. Changing
positon affects the tone and timbre of a played note.
- Manual – The Position setting remains the same, even if notes outside of the position range are played. This allows you to play inside a fret range to maintain realistic sample playback behavior. In the Manual mode, it’s useful to assign the Position Slider to a MIDI control or to Keyswitches.
- Adaptive –The Position changes based on the notes played. Use this mode to explore the variations in tone across the fretboard without manually changing the active position. When a note is played outside the current range, the position will shift accordingly. The next notes to play will be in this new position range. The Position Slider is inactive in the Adaptive mode.
Note: The Position control cannot be automated by the host. You can, however, assign the slider to a MIDI Control (that you can edit) or use the Keyswitch Editor (see p. 14) to achieve sample-accurate position changes.
Pedalboard
The pedalboard contains seven pedals that can be activated either
separately or in combination, offering many sound design options. The first
five pedals are pre-amplifier in the signal flow; the last two occur post-
amplifier.
FX Pre
The FX-Pre section consists of five pedals, wired in the following order:
Compressor, Overdrive, Wah, Phaser, and Chorus. These effects were designed
specifically to complement the Slapping technique. Each pedal has parameter
controls and a bypass button, and is suitable for live use or automation.
Compressor
This is a standard compressor with Amount and Ratio knobs.
- Amount is used to set how much of the signal will be compressed
- Ratio determines the amount of compression.
Overdrive
- This is a parallel overdrive that features Mix and Gain knobs, as well as a Hi-Gain switch.
- The Mix knob sets the balance between the clean and driven signal.
- Gain controls the amount of distortion.
- The Hi Gain switch boosts the gain further, allowing for a wider spectrum of driven tones.
Wah
This is a two-in-one “Wah” pedal that can follow the playing dynamics as well
as the set values of Speed and Sens.
- Trigger selects between the two filter modes:
- In: Filter envelope will respond to the incoming audio signal (velocity sensitive).
- Key: Filter envelope will be triggered based on incoming MIDI notes.
- Mix sets the balance between clean and filtered signal.
- Freq sets the cutoff frequency for the filter.
- Sens determines how sensitive the filter is to dynamics (Input mode) or the depth of the envelope (Key mode).
- Res is used to sharpen or flatten the cutoff response.
- Attack controls how long it takes for the filter to open.
Phaser
This is a parallel phaser pedal with Mix, Depth, and Rate controls.
- Mix controls the balance between the dry and wet signals
- Depth controls the amount of modulation.
- Rate determines the speed of the modulation.
Chorus
This is a parallel chorus pedal with Mix and Depth knobs.
- Mix blends in the processed signal.
- Depth determines the amount of modulation.
FX Post
The FX Post section contains delay and reverb pedals, each with parameter
controls and a bypass button.
Delay
A delay pedal with Mix, Feedback, and Time knobs.
- The Mix knob controls the balance between the Dry and the Wet signals.
- The Feedback (FDBK) knob determines the time it takes for the repeats to decay.
- The Time knob provides control over delay time in Sync rates (such as ¼ note) or Free rates (in milliseconds), using the same knob. The middle position, 12 o’clock, is the slowest Free value. Turning the knob clockwise from this position increases the rate. When the knob setting is less than 12 o’clock, values are defined with respect to the host. Turning the knob counterclockwise increases the rate through musical note values related to the host’s BPM.
Reverb
A parallel reverb pedal that features Mix and Time controls.
- The Mix knob controls the balance between the Dry and the Wet signals.
- The Time knob determines how long it will take for the reverb to decay.
Output Clip Indicator
On the right side of the display is an output level indicator. The meter is
not scaled, but it indicates if your output level is particularly high or low
so that you can adjust your controls accordingly. On the top of the meter is
an output clipping indicator that glows red if a clip has occurred. Click on
the light to reset.
WaveSystem Toolbar
Use the bar at the top of the plugin to save and load presets, load sample libraries, compare settings, undo and redo steps, and resize the plugin. To learn more, click the icon at the upper-right corner of the window and open the WaveSystem Guide.
Sample Libraries
The first time the plugin is instantiated or the application is launched, Bass
Slapper opens a browser so that you can locate and select a samples library
folder. This will become the default folder. To change to another samples
library (e.g., SD to HD), click on the Samples button and navigate to another
sample library folder. A selected library remains the default until you load
another library.
The folder must contain valid Waves sampled instrument files, otherwise the OK button will be grayed out. You can download Waves sample libraries from the Waves download page: http://www.waves.com/downloads/sample-libraries
Tune
Allows global fine tuning of the instrument. By default, the instrument is
tuned to the common standard A=440. Use the Tune control to adjust to
alternate tuning systems or to tune with other instruments in your session.
For example:
To tune the instrument to an A=442 standard, set the Tune control 8 cents
sharp.
To tune to A=432, set it to 32 cents flat.
Range: -100–100 cents
Initial Value: 0
Reset Value: 0
Continuous control
Velocity
When the Velocity button is checked, the Velocity setting does not change when a preset is loaded. When the Velocity button is unchecked, the velocity setting will load to the value specified by the preset.
Save MIDI Mapping
You can use external MIDI controllers with the “Learn” function. To save your
MIDI settings (including Keyswitch Editor settings), open the Save menu from
the WaveSystem Toolbar and choose “Save MIDI Map To New File”. Once you are happy with the Midi Mapping of the
instrument, set it as the Default MIDI Map.
Bass Slapper Standalone Application
The Bass Fingers application can be used as a standalone instrument. It requires ASIO drivers for Windows or Core Audio for macOS. Bass Slapper.exe (Win) or Bass Slapper.app (Mac) loads the Bass Slapper instrument and configuration preferences dialogs. Set up the standalone application from its File menu:
- All Notes Off Sends an All-Notes-Off MIDI command. This is useful in cases of “stuck” sustaining notes.
- Preferences Displays the Preferences dialog for the Audio, MIDI, and User Choices configurations.
PREFERENCES
Active MIDI Inputs displays a list of available MIDI input devices on the
current system. Select the MIDI device for receiving MIDI data.
Tempo: Sets the tempo for all relevant plugins. By default, tempo-based Waves
plugins are in a “tempo listen” state. Their tempo rates will fix to this
value.
Output displays the audio devices available on the system.
Test plays a sound if the outputs are configured correctly.
Active Output Channels allows selection of audio outputs from the selected
device.
Sample Rate displays and sets the sample rate.
Audio Buffer Size displays and sets the buffer size, which influences
latency.
*In Windows, sample rate and buffer size cannot be changed from this panel. To modify these settings: close the application, adjust sample rate and buffer size with your driver’s control panel (link shown below), and then relaunch.
