Introduction

Thanks for choosing the DigiTech® SDRUM™

Strummable Drums™ Pedal. The SDRUM is the

world’s first intelligent drum machine for guitarists

and bassists. The SDRUM provides a quick, fun

way to create professional-sounding drum

patterns for practice sessions, exploring song

ideas, recording, and performing.

There are two ways to create drum patterns with

the SDRUM: using the pads or using BeatScratch™,

a proprietary technology that allows kick/snare

patterns to be created by simply scratching the

upper and lower strings of an electric guitar,

acoustic guitar (with pickup), or bass. This allows

the SDRUM to learn drum patterns using a

method commonly used by guitar and bass

players to explain a beat to a drummer.

Once a kick/snare pattern is created, the "right-

hand" drum element (hi-hat, ride, tom, etc.) is

automatically added to complement the drum

pattern. The right-hand drum element can then

be further edited to suit the song.

The SDRUM can learn up to 3 parts per song and

store up to 36 songs. Each song and part have

various settings that can be adjusted at any time.

These include time signature, feel (straight or

swing), embellishment amount (how busy the

part is), part intensity, tempo, and more.

The SDRUM's drum sounds, from RealiTone™ and Digital Sound Factory®, incorporate samples using multiple

velocity layers, for realistic dynamic expression. Tasteful random beat variations, added ghost notes, and

humanization keep the drums interesting and provide the feel of a true performance.

The SDRUM offers five drum kits to select from, covering a wide range of genres. Alternate kick/snare sounds are

also available for each kit. The drums are internally processed with Lexicon® reverb, so reverb tails decay naturally

and are never cut off. All of this means that the SDRUM can generate drum tracks that sound very natural,

powerful, organic, and authentic—all with minimal effort and time spent.

Features

• High-quality drum samples with multiple velocity layers, humanization, and minor variations for musical

and realistic drum patterns

• 5 drum kits to choose from: E-Pop, Brush, Percussion, Power, and Clean

User Interface

1. VERSE/CHORUS/BRIDGE PART Buttons

These PART buttons provide access to the three parts that make up a song, and they serve the following

functions:

• Select a Part – Press the PART buttons to switch between each of the three song parts.

• Change Part Intensity – Once a part is selected, repeatedly press the selected PART button to cycle

between the available part intensities (or how loud the part will be played). See 'Changing Song Part

Intensities' on page 22 for more information.

• Enable the Metronome or Count-In Feature – When playback is stopped, press and hold the currently

selected PART button to enable the metronome (when the selected song part is empty) or count-in

feature (when the selected song part contains a drum pattern).

The PART buttons have the following states:

• LED Off – The part has not been learned and is not selected.

• LED Solid Dim (Green, Amber, or Red) – With an empty song selected (SONG LED off), this state

indicates that the part will be automatically created. For example, when a song is cleared, the VERSE

LED will light solid bright amber and the CHORUS LED will light solid dim red, indicating that teaching

the verse will automatically create a chorus part. When a non-empty song is selected (SONG LED dim),

this state indicates that the part has been learned but is not selected.

• LED Solid Bright (Green, Amber, or Red) – The part is selected.

• LED Flashing (Green, Amber, or Red) – The part has been learned, is selected, and the count-in

feature is enabled. The rate of flashing indicates the current tempo of the song. When a part is cleared,

the PART button will flash red briefly. When a song is cleared, all three PART buttons will flash red briefly.

When a part or song is restored via an undo operation, the buttons will briefly flash green.

Connectors and User Interface

2. TEMPO Button

The TEMPO button provides the following functions:

• Tempo Indication – When a song part is empty and the metronome is on, or if a song part is not

empty, the TEMPO LED will flash at the rate of the current song tempo. The TEMPO LED will light red for

the first beat of the bar (during playback), dim green for the subsequent beats, then bright green for

the subsequent beats of the last bar. If the tempo of a song is changed, the subsequent beats will light

amber instead of green to indicate the change. Note that the TEMPO button can be pressed and held to

store the new tempo of the song.

• Metronome – With an empty part selected, press and hold the TEMPO button for ~2 seconds to turn

the metronome on or off. See 'Using the Metronome' on page 11 for more information.

• Tap Tempo – Tap the TEMPO button at the rate of the desired tempo to change the tempo of a song.

• Update Nominal Tempo – If the tempo of a song is altered using the TEMPO button or TEMPO knob,

it will not be automatically stored to the song. To store the updated tempo, press and hold the TEMPO

button for ~2 seconds. This will store the new tempo setting as the nominal (center detent TEMPO

knob) setting.

See 'Adjusting the Tempo' on page 21 for more information.

3. GROOVE/KIT Encoder

Turn then press this encoder to change the drum timing, feel, embellishment amount, and kit. The

following options are available:

• Timing – The first two settings select between 3/4 or 4/4 time signatures.

• Feel – The next two settings select between a straight (ST) or swing (SW) feel.

• Embellishment Amount – The next three LEDs select how simple or busy the drum part will be.

• Kit – The remaining LEDs select between the five available drum kits. See 'Selecting the Drum Kit' on

page 17 for more information.

4. ALT Button (Kick/Snare)

Press this button to select alternate voicings for the kick and snare:

• LED Off – Standard Voicing

• LED Green – Alternate Voicing

The alternate voicings are different for each drum kit. See 'Selecting Alternate Sounds for the Kick/Snare' on

page 18 for more information.

5. LEVEL Knob

This knob adjusts the output level of the drums. Adjust this knob to match the level of the drums to the

guitar.

6. LEARN LED

This LED indicates the following functionality:

• Slowly Flashing Red – Indicates an empty song part is selected.

• Rapidly Flashing Red – Indicates the SDRUM is armed for learning and will begin learning the drum

pattern once the KICK/SNARE pads are played, the guitar is scratched, or the FOOTSWITCH is pressed.

• Solid Red – Indicates the SDRUM is learning the drum pattern.

Connectors and User Interface

7. KICK/SNARE Pads

When the SDRUM is armed to learn, tapping these pads provides a traditional method for teaching drum

patterns. They can also be used when using the SDRUM with an instrument that doesn't have a pickup. See

'Teaching Drum Patterns with the Kick and Snare Pads' on page 12 for more information.

8. SONG Button

Press this button and turn the HATS/RIDES encoder to select a different song. Song selections are displayed

on the LEDs surrounding the HATS/RIDES encoder. Turn the HATS/RIDES encoder to select a song from

one of the three banks (green, amber or red LEDs), then press the SONG button or HATS/RIDES encoder to

load the song. See 'Managing Songs' on page 24 for more information on creating, loading, and copying

songs.

9. HATS/RIDES Encoder

Turn this encoder to select a different variation on how the right-hand drum element is played. Press

this encoder to select between different sub-beat timing options for the right-hand drum element. See

'Selecting Right-Hand Drum Elements' on page 19 for more information on the available options and

using the HATS/RIDES encoder.

10. ALT Button (Hats/Rides)

Press this button to select alternate voicings for the right-hand drum element:

• LED Off – Standard Voicing

• LED Green – Alternate Voicing 1

• LED Red – Alternate Voicing 2

The alternate voicings are different for each drum kit. See 'Selecting Alternate Sounds for Right-Hand Drum

Elements' on page 20 for more information.

11. TEMPO Knob

Turn this knob to change the tempo of the song. The tempo range is from half-speed (fully counter-

clockwise) to double speed (fully clockwise). To store the changed tempo of a song, press and hold the

TEMPO button for ~2 seconds. The center detent position of the TEMPO knob represents the tempo stored

to a song.

NOTE: Whenever the tempo is changed without directly using the TEMPO knob—for example, when

teaching a new drum pattern, loading a new song, or using tap tempo—the TEMPO knob may need

to be moved back to the center detent position before it becomes active again. This prevents sudden

tempo changes if the knob is nudged when the current position does not match the current tempo.

See 'Adjusting Tempo Using the Tempo Knob' on page 21 for more information.

12. PLAY LED

This LED indicates the following functionality:

• LED Off – Indicates the selected song part is empty.

• LED Dim Green – Indicates the selected song part contains a drum pattern and playback is stopped.

• LED Bright Green – Indicates the SDRUM is playing the song.

• LED Flashing – The PLAY LED flashes along with the KICK and SNARE pads when the FOOTSWITCH is

held down to stop playback.

Connectors and User Interface

13. GUITAR AUDITION Button

Press this button to cycle through the Guitar Audition modes. Press and hold this button to calibrate

BeatScratch for a guitar (see 'Teaching Drum Patterns with a Guitar or Bass' on page 13 for more

information on calibrating BeatScratch). This button has three states:

• Off (LED Off) – The guitar will be heard when played.

• Hybrid (LED Dim) – When an empty song part is selected, kick/snare sounds will be heard when

scratching the guitar so that BeatScratch can be used. When a song part that contains a drum pattern is

selected, the guitar will be heard when played so that you can play along with the drums.

• On (LED Bright) – Kick/snare sounds will always be heard when scratching the guitar.

NOTE: The Guitar Audition feature will be automatically enabled (LED bright) after calibrating

BeatScratch. After creating a drum pattern, the Guitar Audition feature will be automatically set to

"Hybrid" mode (LED dim).

14. FOOTSWITCH

This footswitch provides the following functions:

• Arm for Learning – When an empty song part is selected, press the FOOTSWITCH once to arm

the SDRUM to learn a new drum pattern (LEARN LED will flash rapidly). Play the part, or press the

FOOTSWITCH again to force the SDRUM to begin learning the new drum pattern.

• Start Playback – When playback is stopped and a song part is learned and selected, press the

FOOTSWITCH once to begin song playback.

• Stop Playback – During playback, press and hold the FOOTSWITCH for ~2 seconds (or until the KICK

and SNARE pads begin flashing rapidly) to stop playback. Release the FOOTSWITCH as soon as the KICK

and SNARE pads begin flashing to stop the song without a sustaining crash cymbal. Continue holding

the FOOTSWITCH to end a song with a sustaining crash cymbal. Note that the cymbal crash will decay

naturally until the FOOTSWITCH is released or the sustain rings out.

• Clear a Part and Undo – When playback is stopped, press and hold the FOOTSWITCH for ~2 seconds

(or until the selected PART button begins to flash rapidly), then release. The selected song part will now

be empty. Immediately press and hold the FOOTSWITCH again for ~2 seconds to restore the cleared

part.

• Clear a Song and Undo – When playback is stopped, press and hold the FOOTSWITCH for ~4 seconds

(or until all PART buttons begin to flash rapidly), then release. All parts of the song will now be empty.

Immediately press and hold the FOOTSWITCH again for ~2 seconds to restore the cleared song.

NOTE: The currently selected part will be cleared first when clearing a song, but as long as the

FOOTSWITCH continues to be held, then all song parts will be cleared at once.

for the application. The table below describes how the SDRUM will operate depending on which outputs are

connected.

Operation Description

A mono mix of the guitar and drum signal will be sent to the AMP OUT jack.

Complementary equalization will be applied to the drum signal to make it

sound better when played through a guitar amp.

NOTE: When using a guitar amp to play the drums from the SDRUM, set

the amp to run as cleanly as possible in order to avoid distorting the drums.

The drums are pre-EQ'd to sound best through a clean amp with "flat" EQ

settings. If using guitar effects and/or a looper, they should be placed before

the SDRUM when using only the AMP OUT jack.

The drum and guitar signals will be mixed and sent to the MIXER OUT jacks.

If only the left (mono) MIXER OUT jack is connected, the guitar/drum mix

will be mono. If the left and right MIXER OUT jacks are connected, the guitar

signal will be mono and the drum signal will be stereo.

NOTE: The SDRUM does not apply cabinet simulation to the guitar signal.

This allows an acoustic or bass guitar to be used when only the MIXER OUT

jacks are connected.

The guitar signal will be fed to the AMP OUT jack only. The drum signal will

be sent to the MIXER OUT jacks in mono (if only the MIXER OUT L jack is

used) or stereo (if both MIXER OUT jacks are used). If using guitar effects and/

or a looper, they can be placed before or after the SDRUM when using both

the AMP OUT and MIXER OUT jacks.

Making Connections and Applying Power

To connect the SDRUM pedal:

1. Turn down the guitar amp. If connecting to a mixer, turn down the gain/trim controls and lower the faders

on the channels to which you are connecting.

2. Make all connections to the SDRUM as shown in 'Connection Diagrams' on page 8.

3. Connect the included HARMAN power adapter to the SDRUM POWER input connector, then connect the

other end to an available AC outlet and wait for the SDRUM to boot.

4. Turn the guitar volume all the way up, strum the guitar, and then gradually increase the guitar amp volume

until the desired level is achieved. If using a mixer, set the channel faders to unity (0), then raise the gain/

trim controls while tapping the KICK/SNARE pads for the desired level. Set the LEVEL knob to 12 o'clock.

Teaching Drum Patterns

The SDRUM allows drum patterns to be created in one of two ways: using BeatScratch to naturally scratch drum

patterns with a guitar or bass, or using the KICK and SNARE pads, which also allows the SDRUM to be used with

other instruments that don't have a pickup.

When teaching a new drum pattern, the SDRUM will automatically determine the time signature and feel

(straight or swing) settings. Once a new drum pattern has been taught, the detected time signature and feel

settings will be reflected on the LEDs surrounding the KIT/GROOVE encoder. The KIT/GROOVE encoder can then

be used to change the time signature and feel manually if desired.

TIP: If required, the automatic time signature/feel detection of the SDRUM can be overridden and a pre-

determined time signature and/or feel can be pre-selected before teaching a new drum pattern. See 'Pre-

Selecting Timing and Feel Settings' on page 28 for more information.

By default, when teaching the SDRUM a new song, the verse is selected as the active part and, once the verse

drum pattern is learned, the chorus part is automatically generated with drums having the same kick/snare

pattern as the verse, but with a higher intensity and a cymbal pattern instead of the default hi-hats. This behavior

is indicated on the user interface with the VERSE LED lighting solid bright amber and the CHORUS LED lighting

solid dim red.

This means that by teaching a single drum pattern for the verse part, you then have drum patterns for two song

parts, allowing you to instantly start exploring song ideas. If you prefer, you can overwrite the automatically

generated chorus drum pattern with your own, disable the chorus part (CHORUS LED off) before teaching the

verse part, or automatically generate a bridge part as well when the verse part is created (see 'Automatically

Generating a Bridge Drum Pattern' on page 27).

Using the Metronome

The built-in metronome can be used to improve timing and avoid unexpected results when teaching a new

drum pattern, as well as to match the tempo of all parts that make up a song. The metronome is automatically

enabled whenever at least one song part has been learned and an empty song part is selected.

To enable/disable the metronome:

1. Select an empty song part (the LEARN LED should be flashing).

2. Press and hold the TEMPO button for ~2 seconds to enable/disable the metronome. The TEMPO button

will also flash at the rate of the metronome to provide visual tempo indication.

TIP: Pressing and holding the currently selected PART button when the part is empty provides an

alternate way to enable/disable the metronome.

TIP: The tempo can be changed before teaching the new drum part by either tapping in the desired

tempo on the TEMPO button or by turning the TEMPO knob.

NOTE: The default BPM for an empty song is 120. The SDRUM always plays back at an integer BPM,

making it easier to match the BPM of an external device or DAW.

NOTE: In a song where at least one part has already been learned, the metronome will automatically

be enabled when an empty part is selected.

Teaching Drum Patterns

Teaching Drum Patterns with the Kick and Snare Pads

The KICK and SNARE pads on the SDRUM can be used to teach drum patterns in a more traditional manner or

when playing an instrument without a pickup.

To teach a drum pattern with the KICK and SNARE pads:

1. Ensure an empty song part (VERSE, CHORUS, or BRIDGE) is selected. The LEARN LED will flash if the

selected part is empty.

TIP: When an empty song is selected (SONG LED off), the VERSE LED will light solid bright amber

and the CHORUS LED will light solid dim red. This indicates that teaching the verse will automatically

generate a chorus part. If you wish to create a custom pattern for the chorus part instead, disable

the automatic part generation feature before teaching the SDRUM by pressing the CHORUS button

repeatedly until the CHORUS LED turns off. Note that the automatically generated chorus part can also

be cleared and a new pattern taught after teaching the SDRUM if preferred.

For information about automatically generating a bridge drum pattern along with the verse and

chorus, see 'Automatically Generating a Bridge Drum Pattern' on page 27.

2. If desired, enable the metronome by pressing and holding the TEMPO button for ~2 seconds. Set the

tempo by tapping the TEMPO button at the desired rate or by turning the TEMPO knob.

3. Press the FOOTSWITCH to arm the SDRUM. The LEARN LED will begin flashing rapidly to indicate the

SDRUM is armed.

4. Begin playing the drum pattern on the KICK and SNARE pads.

TIP: Alternatively, press the FOOTSWITCH to start learning without needing a pad hit. The LEARN LED

will light solid red, indicating that the SDRUM is learning. This can be useful for certain music styles

that incorporate drum patterns that have no kick or snare hit on the first downbeat of the bar, such as

reggae.

NOTE: When creating a new drum pattern, the maximum length cannot exceed 4 bars.

5. Press the FOOTSWITCH when done. For best results, try to press the FOOTSWITCH on the same downbeat

you started on (beat 1).

6. The drum pattern will begin playing. Play the guitar and adjust the LEVEL knob for a good blend between

the guitar and drums.

7. To stop playback, press and hold the FOOTSWITCH for ~2 seconds (until the KICK and SNARE pads begin

flashing). Releasing the FOOTSWITCH as soon as the KICK/SNARE pads begin flashing will stop playback.

Continuing to hold the FOOTSWITCH will cause a crash cymbal to play at the end of the current bar and

ring out for as long as the FOOTSWITCH is held.

TIP: The SDRUM offers some advanced features that can enhance SDRUM operation when creating a drum

pattern. See 'Advanced Features and Tips' on page 27 for more information on the options available and

how to use them.

Teaching Drum Patterns

Teaching Drum Patterns with a Guitar or Bass

The all-new BeatScratch feature allows a guitar or bass to be used to teach the SDRUM a drum pattern. When

doing so, the SDRUM should first be calibrated for the connected guitar/bass.

To calibrate BeatScratch for a guitar/bass:

1. Adjust the guitar/bass pickup position and tone control for the desired tone.

2. Press and hold the GUITAR AUDITION button for ~2 seconds. The KICK pad will begin flashing and the

HATS/RIDES LEDs will all turn red. Keep the guitar/bass quiet until you're ready to begin the calibration

process.

3. Mute the strings with your fret hand, then strum only the low strings in the way that you wish to teach kick

drum hits. With each detected hit, the HATS/RIDES LEDs will go off one by one. Stop once all twelve kick

events have been received (all the HATS/RIDES LEDs will go off, the SNARE pad will begin flashing, and the

HATS/RIDES LEDs will all light red again).

4. Mute the strings with your fret hand, placing your hand in the same position on the neck used for the kick

calibration, then strum only the high strings in the way that you wish to teach snare drum hits. With each

detected hit, the HATS/RIDES LEDs will go off one by one. Once twelve snare events have been received

(all the HATS/RIDES LEDs have gone off), the SDRUM will exit calibration mode.

5. Once calibration is complete, scratching the guitar/bass will generate kick and snare sounds.

NOTE: Calibration settings are retained, even after a power cycle.

TIP: If playing bass, try using a pick if fingering or plucking the strings is not working. Feel free to experiment

with different ways of teaching the SDRUM to discover what works best with your instrument and teaching

style. Some bass players have found that slapping the lowest string and popping the highest string works

well.

Teaching Drum Patterns

To teach a drum pattern with a guitar/bass:

1. If the guitar/bass has not yet been calibrated to use BeatScratch, first follow the calibration instructions

above before proceeding.

2. Ensure an empty song part (VERSE, CHORUS, or BRIDGE) is selected. The LEARN LED will flash if the
