■Advanced drum machine, a "rhythm synthesizer" based on a mix of virtual analog modeling synthesis and PCM samples. Main panel features a segments display, 16 pads, a data entry wheel, 11 knobs and 34 rubber buttons.
Later replaced by Korg Electribe R MkII - part of the following second electribe generation, quite the same as Mk1 but Korg added a cross modulation effect between oscillators
■VOICE Main CPU H8S2350 manages 6 voices polyphony (tms5707FFT DSP + DAC AK 4522) each with individual volume, Midi channel and panning position. Voices are allocated between part A and B:
A--> 4 parts VA analog modeling percussion synthesizers
B--> 4 parts PCM samples playback but only 2 voices since hihats and crash are channel-shared.
■ PART A: ANALOG 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
■ PART B SAMPLES ROM
contains only 4 PCM waveforms:
■ 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 bipolar modulator, relative frequency range between 0.1Hz and 5kHz with variable depth. The LFO features 6 shapes:
- noise: adds a white noise to the sound, indicated for snare
- envelope: is effective for kick drum sound creating
- sample and hold: is very indicated for bleeps or analog-like noises
■SEQUENCER classic Roland TR STEP mode for beat programming.
Variable time signature (4/4 or 3/4 or triplet timing) and other functions e.g 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.
■EFFECT only a cross-feedback digital delay with adjustable feedback rate and sync to tempo mode. Both PCM and modeling V.A can use the special LOW BOOST for more bass EQ gain.
■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).
- 16 songs
- 256 patterns (each 64 steps)
- 35700 recorded events
All data can be saved only to Midi dump process
