Korg Electribe ER1
Rhythm Synthesizer (1999)


Advanced drum machine, a true "rhythm synthesizer" based on a mix of virtual analog modeling synthesis and PCM samples.

Part of the famous ELECTRIBE series mainly aimed at performance and live purposes.

rhythm synthesizer

info DRUM MACHINE (weight: 1.75 Kg) portable machine.
Main panel features a basic segments display, 16 pads, a data entry wheel, 11 knobs and 34 rubber buttons.

Rear panel terminal connectors:
- Midi interface
- main out
- headphones
- 2 inputs for external processing or gating-triggering.

ac Power supply
is a 9V external PSU negative in center 600 mA.

edit VOICE the ER-1 manages up to 6 voices polyphony each with individual volume, Midi channel and panning position.

STRUCTURE: voices are allocated into part A and B:
1-->4 parts VA analog modeling percussion synthesizers.
2-->4 parts PCM samples playback but only 2 voices since hihats and crash are channel-shared.


editANALOG MODELING section is composed by 4 parts each can be either a sinewave or triangle waveform with a pitch tuning from 20 to 12000 Hz.
A special ring modulation process can be applied between:
- part 1 / part 2
- part 4 / audio input.



SAMPLES there are only 4 PCM waveforms:
- channel 1: open/closed hithats or crash cymbal
- channel 2: handclap.



edit ENVELOPE only the DECAY segment can be set for both PCM and VA sections but it also works as a signal gate for external sources process.


LFO a single modulator with positive or negative modulation, and a frequency range between 0.1Hz and 5kHz with variable depth.
The LFO features 6 shapes:
1- sawtooth
2- square
3- triangle
4- noise: adds a white noise to the sound, mostly indicated for snare
5- envelope: is effective for kick drum sound creating
6- sample and hold: is very indicated for bleeps or strange analog-like noises
TECH: the pitch modulation can be applied only to VA part and not to samples.

edit SEQUENCER classic Roland TR STEP mode for beat programming.
Variable time signature (4/4 or 3/4 or triplet timing) and other functions like accent, clear events, copy and swinged mode (humanize). Special MOTION SEQUENCER records and loops knobs movements then values can be played back as is or interpolated for a smoother sequencer effect.
SYNC internal frequency tempo from 20 to 300 BPM or unit can be slaved to external Midi clock and other Electribes machines.



edit EFFECT only a cross-feedback digital delay with adjustable feedback rate and sync to tempo mode. Both PCM and modeling VA can use the special LOW BOOST for more bass EQ gain.

edit MIDI every parts (including audio input) are assigned to a Midi note and channel.
The Midi implementation is poor and knobs cannot be recorded by Control Change but only NRPN (Non Registered Parameters).

edit MEMORY :
- 16 songs
- 256 patterns (each 64 steps)
- 35700 recorded events
All data can be saved only to Midi dump process

REVIEW "A LOT of sound can be created on the fly there! Now cheap! A bit limited as single drum machine but ER1 can be a precious source of inspiration on the fly."
