The Electribe/R ER-1 is a unique and easy-to-use rhythm instrument that uses DSP synthesis tech-
nology to help anyone from beginners to hard-core users to produce truly original music.
By using the front panel knobs and keys, you can create analog percussion sounds intuitively, and
easily create rhythm patterns using these sounds.
The ER-1 is the ideal tool for the musician, DJ, sound creator, or desktop-music user who is looking
for originality in their music.
Main features
• The ER-1 is a simple, analog-feeling percussion synthesizer with a four-part percussion synthe-
sizer, two audio input parts, four PCM sound parts, and an accent part.
• By combining percussion sound with audio input (external input) rhythms, the ER-1 gives you the
expressive possibilities of a completely new type of rhythm machine.
• The Motion Sequence function lets you record and loop knob movements, and these patterns can
be recorded independently for each part.
• Sixteen step grid input is featured --- the ideal way to input rhythms. It's also easy to record in
realtime.
• You can quickly modify sounds or rhythm patterns to change your performance while you play.
• Sounds you create and up to 256 original rhythm patterns (each up to 64 steps long) can be stored
in memory.
• Up to sixteen songs can be created by combining multiple patterns and adding knob movements
etc. (event data), and stored in memory.
• Delay and low-boost effects are provided.
• Pattern Set Play lets you register sixty-four patterns in the sixteen step keys, and switch patterns as
you perform.
• Tap tempo and MIDI Clock can be used to synchronize the ER-1's performance with an external
sequencer or turntable etc.
• The ER-1 can be controlled from an external sequencer or keyboard etc., and used as a MIDI expan-
sion tone generator.
• The MIDI Dump function lets you save data on a computer or external sequencer etc.
About the data you create on the ER-1
Patterns and songs that you create on the ER-1 by editing will return to their un-edited state if you
select a different pattern or song, or turn off the power before performing the Write operation.
If you wish to save an edited pattern, song, or global data, be sure to perform the Write operation.
Even after Writing the edited data, it is still possible to restore all songs and patterns etc. to the factory
settings. (Refer to p.44 "Restoring the factory setting data.")

Striking keys to play Parts
By striking the part keys, you can play the corresponding sounds.
The audio-in parts will sound when an audio signal is connected to the audio
input jacks. (Refer to p.19, "Connecting various sources to the audio inputs.")
However even if sound is being input, it will not be heard if Audio In Thru is
turned on.
The sound of each part will differ depending on the pattern. Rotate the dial to
switch patterns, and enjoy the wide range of sounds.
Parts for which the Ring Modulation Key is turned on will not sound unless their keys
are pressed simultaneously (refer to p.25 "Modulation").
Pressing the Accent key will not sound the Accent part.
It is not possible to simultaneously play both the Close and Open hi-hat sounds.
It is not possible to simultaneously play both the crash cymbal and the handclaps.
What is a Part?
A Part consists of the timing at which sounds are produced (i.e., a rhythm pattern), and a motion sequence. Parts are the
smallest unit of data from which a Pattern is created. There are the following types of Parts, and
a total of eleven Parts. (Refer to p.22 "Pattern
mode.")
• Percussion Synthesizer parts (1--4): A synthe-
sizer sound and a rhythm pattern.
• Audio In parts (1, 2): A rhythm pattern for the
external audio input.
• Hi-hat parts (Close, Open): A rhythm pattern
for the hi-hat.
• Crash Cymbal part: A rhythm pattern for the crash cymbal.
• Handclap pattern: A rhythm pattern for the handclap.
• Accent part pattern: A rhythm pattern for the points of emphasis (accents) for the overall pattern.
You are free to modify the sound of each part, and rhythm patterns and motion sequences can be stored
independently for each part (refer to p.24 "Editing the sound of a part").

Modifying (editing) the sound
1. Press a part key to select the part that you wish to edit.
2. Use the knobs and keys of the Synthesizer section to edit the sound. The
Original Value LED will light to indicate the position of the knobs and
keys for the original settings of the sound.
Refer to the example sounds (p.45) and try creating your own sounds.
The pattern sound that you modified here can be saved by the Write operation (p.17 "Saving a pattern you create").
The knobs that are effective will depend on the pattern.
If a motion sequence is controlling a knob, it may be difficult to edit the
sound as you intend. If so, turn the motion sequence off while you are
editing (refer to p.28 "Motion sequences").
What is the synthesizer section?
This is the section where the parameters assigned to the panel knobs and keys work together to "synthesize" (produce) the sound of each part. (Refer to p.24 "Editing the sound of a part.") The knobs that are
valid for each part are as follows.
• Percussion Synthesizer parts: Wave, Pitch, Mod Type, Mod Speed, Mod Depth, Decay, Pan,
LowBoost, Level
• Audio In parts: Decay (functions as gate time), Pan, LowBoost, Level
Striking the part keys along with a song or
