Controlling the parameters
Each eect unit lets you control the parameters by using the GRIFFER (GRF) knobs which allow 
high-precision adjustment, and by inputting a CV/GATE signal.
The settings of the GRIFFER (GRF) knobs are added to the CV/GATE signal.
The indicator beside the knob changes its brightness according to the knob position and the 
voltage of the CV/GATE signal.
This manual explains the factory-set parameters of the GRIFFER knobs and the buttons.
By using the dedicated software, you can reassign these to the desired parameters. (
 * In the tables below, “B” indicates BITRAZER, “D” indicates DEMORA, “T” indicates TORCIDO, 
and “S” indicates SCOOPER.
Model Indication Explanation
B SAMPLE RATE Lowers the sampling rate to create a noisy sound.
D TIME Adjusts the delay time.
T DIST Adjusts the depth of distortion.
Adjusts the amount of scatter.
“Scatter” adds a digital-feeling groove to the loop playback by 
exchanging individual steps within the loop playback and also by 
changing the playback direction or gate length.
Adjusts the amplitude of the CV signal (voltage) that is input to GRF 1.
 * When the knob is minimized (turned fully left), the amplitude is 0.
Model Indication Explanation
B FILTER CUTOFF Adjusts the cuto frequency of the lter.
D FEEDBACK Adjusts the volume of the delay sound.
T TONE Adjusts the tonal character of the distortion.
S SCATTER TYPE Adjusts the type of scatter.
Adjusts the amplitude of the CV signal (voltage) that is input to GRF 2.
 * When the knob is minimized (turned fully left), the amplitude is 0.
Model Indication Explanation
B BIT DOWN Lowers the bit depth to create a lo- sound.
Adjusts the volume of the pingpong delay sound (the delay heard 
alternately from OUTPUT 1 and 2).
T TUBE WARM Produces a warm sound as if it were passing through a vacuum tube.
S PITCH Adjusts the pitch depth.
Model Indication Explanation
B RESONANCE Emphasizes the sound in the region of the cuto frequency.
D T DRY/WET Adjusts the balance of the dry sound and wet sound.
S FILTER Adjusts the eect of the lter.
Model Indication Explanation
B LPF/HPF Switches between a low pass lter and high pass lter.
D HOLD Continues holding the delay sound.
T LO BOOST Boosts the low-frequency sound.
Uses the GATE signal input to control the operation of the [REC/
 [REC/PLAY] button (SCOOPER only)”
Model Indication Explanation
B D T BYPASS Bypasses the eect so that no eect is applied.
S SCATTER Turns the SCATTER eect on/o.
 INPUT 1/2 jacks, OUTPUT 1/2 jacks
These are two monaural input/output jacks.
 * To prevent malfunction and equipment failure, always turn down the volume, and turn 
o all the units before making any connections.
“Using the Dedicated Software”)
Connect this to your tablet so that dedicated software settings can be input as audio signals.
When an audio signal is input to the [REMOTE IN] jack, the color or illumination of the center 
indicator shows the reception status.

 * If the center indicator does not change when you input an audio signal, or if a reception 
error occurs, adjust the volume of the tablet and input the signal again.

Lights when the power is on. The color and illumination indicates the status of this unit.
 * For BITRAZER, DEMORA, and TORCIDO, this indicator is unlit when you turn BYPASS on. 
For SCOOPER, this indicator is o if SCATTER is o and there is no recorded loop phrase.
 [REC/PLAY] button (SCOOPER only)
If a GATE signal is not being input to the “GRF 5 SYNC TRIG,” recording (REC) or playback (PLAY) 
starts the moment you press the button.
If a GATE signal is being input to the GRF 5 “SYNC TRIG,” recording (REC) or playback (PLAY) 
start the moment a GATE signal is input after you press the button.
Connect a Eurorack power cable, or the included AC adaptor.
This turns the power on/o.
“Using the Dedicated Software”: “Using the dedicated software 
Use a commercially available USB 2.0 cable (A-microB type) to connect your computer.
If this is connected, you’ll be able to edit the parameters of this eect unit from your 
computer. You’ll also be able to use your computer to record and store the input from the 
INPUT 1/2 jacks and CV/GATE jacks and the output to the OUTPUT 1/2 jacks.
 * You must install the USB driver before connecting the eect processor to your computer. 
Download the USB driver from the Roland website. For details, refer to Readme.htm which is 
included in the download.

Using the Dedicated Software
Dedicated software lets you add a lter or LFO, or to assign the desired parameters to the 
knobs and buttons by using your tablet or computer.
By assigning parameters that are dierent than the initial parameters, you can also use this 
unit virtually as a dierent eect processor.
You can access and download dedicated software for your device from the following 
locations. For details on the dedicated software, refer to the help that is included with the 
Device Destination website
Android tablet Google Play

Using the dedicated software on a tablet
Use a patch cable to connect this unit's REMOTE IN jack to your tablet's headphone jack.
Using the dedicated software on a computer
Use a separately sold USB 2.0 cable (A-microB type) to connect the USB port on the rear panel 
of this unit to your computer.
 * In order to connect this unit to your computer, you must install the USB driver.
Using a Eurorack Power Cable
In addition to an AC adaptor, the unit can also be operated on Eurorack system power (+12 V) 
by using the included Eurorack power cable.
Insert the 16-pin connector of the Eurorack power cable into the Eurorack power 
connector. When inserting the connector, align it with the groove.
If there is no groove, align the wire bearing the red mark with pin number 1.
Connect the other connector of the Eurorack power cable to the DC IN jack of this unit.
 * The +12 V power of the unit draws 450 mA of current. Use a power supply that can 
deliver this amount of current.
For more about Eurorack power supply units, refer to the Roland website. Here you can 
nd the latest information about units that have been veried to be compatible.

Observing the cautions listed below, turn on the rear panel [POWER] switch.
 * This unit is equipped with a protection circuit. A brief interval (a few seconds) after turning 
the unit on is required before it will operate normally.
 * After you’ve made connections correctly, be sure to turn on the power in the order of 
the eect processor rst, and then the connected system. Powering-on in the incorrect 
order may cause malfunctions or damage. When turning the power o, power-o the 
connected system rst, and then the eect processor.
 * Before turning the unit on/o, always be sure to turn the volume down. Even with the 
volume turned down, you might hear some sound when switching the unit on/o. 
However, this is normal and does not indicate a malfunction.
CV stands for “Control Voltage,” an electrical signal (control voltage) 
that modies the behavior of an analog synth or Eurorack module. 
GATE is a trigger signal that controls the beginning and end of an 
envelope or other control voltage.
 * This unit can receive CV in the range of “-10 – +10 V.” Adjust your 
output device to stay within this range that can be received. You 
must input a gate voltage of “+3 V” or higher.
 * Use patch cables with monaural mini-plugs to connect other
