Preface
Thank you for purchasing WaveU. We are convinced that it will bring you a
lot of joy in the future and above all a lot of momentum to your now 30-
year-old U-110 or U-220.
Why you should read the manual
Manuals are usually unpopular, boring or even annoying. We have made
every effort to make sure that you don't fall asleep after reading the first
two pages.
Whether you read this manual is up to you, you can also put it aside. How-
ever, you should know that this manual informs you about the correct use
of WaveU. You will also find important safety instructions that you must fol-
low. They are highlighted in gray and therefore easily recognizable. You
don't want to expose yourself and your environment to unnecessary dan-
ger, do you?
Your WaveReX Team
This is a product to praise the glory of Roland and its outstanding
musical products!

Safety instructions
Please read these safety instructions carefully. It is essential that you un-
derstand these instructions in order to use WaveU safely.
Keep the safety instructions handy until the end of WaveU's life.
If you have any questions or are unsure how to use WaveU, contact our
support team immediately.
WaveU is a plug-in card for the PCM CARD slots (ROM) of the Roland U-
110 and U-220. It serves as a replacement for the PCM cards of the Ro-
land company.
ATTENTION!
Only insert WaveU into the designated card slot. Make sure that the card
is oriented correctly.
WaveU was developed for use in private households as well as for use in
recording studios.
ATTENTION!
Use outside closed rooms can cause damage to WaveU and your device.
Use WaveU only indoors.
Due to its design, WaveU is particularly sensitive to inappropriate force ef-
fects.
ATTENTION!
Do not attempt to bend, compress or twist WaveU. Never force WaveU
into the card slot of your device. Do not drop WaveU or apply force to the
card.
WaveU is an electronic product. It contains state-of-the-art electronic com-
ponents and was developed and built according to the current state of the
art.
ATTENTION!
Use WaveU only in rooms with room temperature and low humidity. Do not
expose WaveU to liquids. This can damage or even destroy the electronic
components.
WaveU's housing protects the underlying components and serves as an
insertion aid into the card slot.
ATTENTION!
Never open the card. This can destroy the card and the electronic compo-
nents. A defective housing can no longer guarantee proper insertion into
the card slot. This can lead to malfunction or destruction of WaveU or even
your device.
WaveU's contacts are gold-plated to withstand mechanical demands
longer. Nevertheless, this is a contact-based technology.
ATTENTION!
Even though WaveU is designed to last, try to remove WaveU from the
card slot only when necessary.
WaveU works with non-hazardous voltages.
ATTENTION!
However, you should avoid touching the gold contacts. The contacts can
be permanently attacked by the skin grease. And don't even think about
licking the contacts!
Metal objects on the contacts can cause short circuits.
ATTENTION!
Never short-circuit the contacts! This will destroy WaveU and can cause
you serious physical damage!
A defective WaveU can severely damage your device.

Safety instructions

ATTENTION!
Do not use WaveU if it has any obvious damage. If you are not sure, con-
tact support.
A defective device can severely damage your WaveU.
ATTENTION!
Do not use WaveU if your device has a defect. Faulty voltages, short cir-
cuits etc. can destroy the card.

Intended use
page 9 of 30
Intended use
WaveU has been designed exclusively for the RS-PCM Sound Modules of
the U series from Roland Corporation Japan and is compatible only with
these devices. It is designed to be used in the PCM CARD slot (ROM) of
the device.
Attention!
Never use WaveU in incompatible devices. You can destroy your device
and WaveU!
The warnings in this manual and on the back of the card must be read, un-
derstood and applied.
Reasonably foreseeable misappli-
cation
WaveU must never be inserted into a card slot that is not labeled PCM
CARD, such as a card slot RAM CARD, which is designed exclusively for
program memory cards.
WaveU contains sensitive electronics. The card must not be exposed to
weather conditions as this may destroy the electronics.
WaveU may only be used for the purpose described in this manual. Any
misuse of WaveU is considered improper use.
WaveU has only been tested in U-series devices. Even though WaveU is
technically identical to the SN-U110 cards, you use WaveU in the Roland
D-70 at your own risk.
Preparation
To connect WaveU to your computer you need a micro USB cable. This is
not included in the delivery.
You can also use a USB extension, but make sure that the total length
does not exceed 5m. This is not included in the delivery.
Up to Windows 7 you need a USB driver. You can download it from the
download page www.waverex.de/downloads/.
If you use Windows 8 or higher you don't need any drivers.
To create your own cards and upload them to your WaveU you need the
software editor from WaveReX. Download it from the download page
www.waverex.de/downloads/. Make sure you always use the latest version
so you don't miss any updates or bugfixes.
Even if you have already turned on your U with anticipation, turn it off first
and be patient for a moment.
In the following we will introduce you to the functionality of WaveU and the
software editor with a kind of quickstart. If you are familiar with the basic
principles of the sound generation of your device, you can start right away.
However, we recommend that you first read the chapters Basics and
Technical Data. Here you will find a basic explanation of how the whole
system works and what you should pay attention to.

The Hardware
page 10 of 30
The Hardware
①–WaveU card
②–Micro-USB-connector
③–Status LED (green)
④–Transmission LED (blue)
⑤–Contacts (back side)
The USB port
The USB port on your WaveU is used to transfer data from your computer
to WaveU. It is a USB-B micro connector.
WaveU is powered by both your device and USB, whichever is higher.
Attention!
When new, the connector may still be a little tight. Never insert your USB
cable with force, you can destroy the connector!
The card
The card was manufactured in a sandwich process from conventional
board material (GRP). The layers are both soldered and glued. The cover
is made of stainless steel and protects the internal electronic components.
It is also firmly glued. Trying to open the card or the lid will definitely de-
stroy your WaveU. Under normal circumstances there is no reason for this.
If you have problems with your card not being recognized, please refer to
the Troubleshooting chapter.

The software editor
page 11 of 30
The software editor
In the main window you can manage and edit your compilations. Here you
can add tones, edit them and load your compilation onto your WaveU. You
can also preview your samples here and always have an overview of the
used memory size.
The content of the main window represents the content of your virtual
card. All tones listed in the Tones list are loaded onto the WaveU and are
then available in the U as card sounds. 128 tones are possible per card.
The user interface
“New Card”Button
Press this button if you want to discard your composition and create a new
one.
“Open Card”button
With this button you can load previously saved compositions into the edi-
tor.
Note that you can only open files with the extension *.wru.
Also note that opening a card will permanently erase your current compila-
tion. Therefore, always save your work before loading a card.
“Save Card”button
With this button you can save your compilation as a virtual card (image).
Cards are saved with the file extension *.wru.
“Save Card As”button
Saves your compilation under a different name.

The software editor
page 12 of 30
General area Here you can change the name of the
card as it is displayed in the U, as well
as the name of the tone. You can also
set the Tone Type and the Velocity
Curve for Voice 1 and 2 using the
drop-down fields.
The Velocity Threshold knob can be
used to set the threshold value of the
velocity between Voice 1 and 2, espe-
cially for the Tone Type Velocity
Switch. If e.g. 64 is set as Threshold,
all velocities up to 64 Voice 1 and all
velocities from 64 Voice 2 will be
played.
The Voice Ratio knob determines the ratio between Voice 1 and Voice 2
for tones with two voices.
Play button
Press Play to preview the currently selected sample. Alterna-
tively, you can press the space bar.
Card-Info
Here you will always see information
about the size of the compilation.
Note that you must not exceed a
size of 512kb. 12288 bytes are basically occupied by the card format.
Tones list All tones listed here are subsequently available as
a tone within a timbre in the U.
Use the Plus (+) button to add a new, empty tone
to your list.
Select an instrument and press the Minus (-) button
to delete the tone from the list.
Mark an instrument and use the arrow keys on the
right side of the list to change the arrangement of
the instrument within the list.
128 tones can be created per card. The list is
therefore limited to 128 tones.

The software editor
page 13 of 30
Transfer In the Transfer area you will find the
Device selection field. All WaveUs
that are connected to your computer
are displayed here. Use the selection
box to choose the WaveU that you
want to write to.
You will also find the Send Card but-
ton here, which you can use to trans-
fer your compilation to your WaveU. The progress bar at the bottom in-
forms you about the progress of the transfer.
Knobs
You can operate each knob in several ways.
You can click on it with the left mouse button and move the mouse up or
down. The knob moves in fine steps. To make larger steps hold down the
CTRL key.
Alternatively, you can use the mouse wheel. Move your mouse pointer
over the slider and turn the mouse wheel for small steps or press CTRL for
large steps.
You can also simply click on the numerical value below the slider and en-
ter the desired numerical value directly.

The software editor
page 14 of 30
The Voice-Editor Voice tab
Select here which of the two voices should be displayed and edited in the
Voice Editor.
Waveform display
Here you can see the waveform of the currently selected sample. You
can watch every change of the sample live here.
Samples list
This list contains all samples of the currently selected voice and repre-
sents a multisample. Multisamples contain several samples which can
be distributed over several keyboard zones.
Use the Plus (+) button to add a new, empty sample to your list. Then
double-click the sample to assign a file to it. Alternatively, you can add
files to the list by drag&drop.
Select an instrument and press the minus (-) button to delete the sam-
ple from the list.
Mark a sample and use the arrow keys on the right side of the list to
change the order of the sample within the list.
Each voice can contain 12 samples, so the sample list is limited to 12
samples.
Note that you cannot change the name of the samples, because it is not
displayed in the device. The sample names are therefore of no im-
portance.

The software editor
page 15 of 30
Loop settings
Here you can make all settings for the loop and the length of the currently
selected sample.
Activate the checkbox Loop active to activate the looping of the sample.
Use the checkbox below to select between the two loop modes forward
(FW) and backward (BW).
Use the arrow keys at the respective fields to set the offset, i.e. the start,
loop and end point of the sample in single steps. Activate the checkbox
snap at zeros to adjust the step size of the arrow keys to the respective
distance of the zero crossings. The offset is thus set to the next zero
crossing of the sample. This can be helpful when searching for a suitable
loop.
Activate the checkbox lock Loop to keep the loop length when the loop
start or sample end is changed.
Pitch settings
The drop-down field allow you to set the root note for the currently se-
lected sample. This also serves as the top key for the key zone in which
the sample is played. This keyzone is limited downwards by the top key of
the keyzone below it, if present.
If the sample name contains the root note, this can be taken over via the
RootNote from Name button.
The PC (Pitch Correction) knob can be used to adjust the pitch of the sam-
ple (positive only) and the LP (Loop Pitch) knob can be used to adjust the
pitch of the loop (positive and negative) in cent steps.
Best Practice:
To avoid the disadvantage that the pitch correction only works positively,
Roland likes to set the root note of the samples a semitone too low and
compensate the rest via the pitch correction.

The software editor
page 16 of 30
Envelope settings
In the lower part of the voice editor, the envelope for the currently selected
tone can be set using the knobs.
Please note that an envelope always refers to the entire tone. Separate
envelopes for each sample are not supported by the U.
The envelope of the U is basically built up according to the following
scheme:
This scheme is already known from other Roland devices and corresponds
most closely to an AHDSR envelope. The envelope has a few peculiari-
ties, which we will discuss in more detail later.
T1 represents the time until the level of the sample has risen to the value
L1. T1 is comparable to the attack time and L1 to the attack level. The
course of this part of the envelope is always linear.
T2 is the time until the level has changed from L1 to L2. L2 can be higher
or lower than L1. If both levels are the same, it is a classic hold. The
course of this part of the envelope is also always linear.
T3 is the time in which, starting from L2, the sustain level L3 occurs. This
curve is either concave, if L2 is larger than L3, or convex, if L2 is smaller
than L3. The degree of curvature can be adjusted via the Shape parame-
ter.
The last parameter, T4, corresponds to the classic Release Time and rep-
resents the time it takes for the sample to drop from sustain level L3 to
zero. This time starts as soon as the keyboard key is released.
The expected envelope is displayed in blue in the waveform window when
you move the mouse over one of the controls. In addition, a tooltip shows
  


   

The software editor
page 17 of 30
you the approximate length when you position the mouse pointer over one
of the T knobs.
All level parameters L1 to L3 take values from 0 to 127.
The values are logarithmic and correspond to dB values, but not integer
ones, which is why they are not so memorable. We have therefore decided
to display the integer values. However, if you move the mouse pointer over
the slider, the currently set dB value is displayed via a tooltip.
If you want to know exactly and do all the math, calculate 20 * log10 (x * 1
/ 127). X stands for the integer value set at the controller. The others may
please take the following facts as given:
A halving of the value corresponds to a decrease of 6dB, a doubling of the
value corresponds to an increase of 6dB. In the following, a few values
and their correspondence in dB are briefly exemplary:
127 = 0dB = full volume
113 = ca. -1dB
101 = ca. -2dB
90 = ca. -3dB
64 = ca. -6dB
32 = ca. -12dB
8 = ca. -24dB
1 = ca. -42dB

First steps
The principle of WaveU
With the software editor for WaveU you can compose a virtual card, a so-
called image, on your computer. This image can contain up to 128 tones
and 2 voices per tone. The image can then be transferred from the editor
to your WaveU and used by the U.
Connecting
Turn on your computer and wait until it has booted up.
Take your WaveU out of the box. The side with the label is the top side.
The bottom side has the warning labels.
Do not put your WaveU in the U for now. First place it on a smooth, dry
surface, e.g., a table.
Now take the micro-USB cable and connect it to your WaveU. The other
side of the cable can then be plugged into a free USB port on your com-
puter, it doesn't matter if you use a USB2 or USB3 port. WaveU will be
powered when the green LED is lit.
Your WaveU will start in bootloader mode for five seconds. You can see
this by the double blinking of the blue LED. After that, your WaveU will au-
tomatically start in operating mode.
Starting with Windows 8, Windows should now install the drivers on its
own. Check in the device manager if your device appears as WaveReX
bootloader, then you have done everything right.
Installing the USB driver
If you are using Windows 7 or an older version, you have to install the driv-
ers manually.
Plug your WaveU into the computer. If Windows 7 starts installing the de-
vice drivers immediately, you can simply close or ignore the window.
However, at least the following message should appear in the taskbar:
"The device driver software has not been installed" (Sorry, the pictures are
only available in German)
Go to the Device Manager. WaveReX should appear under Other De-
vices. Right-click on WaveReX and select Update Driver Software....

First steps
page 19 of 30
Select Search for driver software on the computer. Then specify the
folder of the USB driver under Search for driver software in this loca-
tion:
Confirm with Next. Windows will then install the driver for WaveU.
WaveU will be displayed in the Device Manager as WinUsb Device under
Universal Serial Bus devices from now on.

First steps
page 20 of 30
Opening the software editor
Make sure that your WaveU is already connected to your computer. Now
open the WaveU software editor. You have also downloaded it from our
site before. You should now see the main window:
You can see if your WaveU is connected to the software in the lower left
corner of the device overview. The con-
nected WaveU and its serial number are
displayed here.
You can also connect multiple WaveUs. In
this case, you can use the drop-down field
to select the WaveU you want to use.
Loading a card
Click the Open Card button. A dialog box opens. Here you can select a
previously saved card. The files have the extension *.wru.
If your files are in another folder, navigate to the desired folder via the win-
dow.
Double-click on the file or select it and click the Open button. The contents
of the card will be loaded and displayed in the main window.
