The ELECTRIBE*R (ER-1) combines a four-part DSP-based synthesizer with four additional PCM sound sources, providing classic hi-hat and cymbal tones. Its synth voices includes dual oscillators, waveform modulation, amp and panning parameters. Effects include low boost for booming low-end, normal or tempo delay settings. The combination of DSP and sampled sound sources is what gives the ER-1 its unique character - the voice is much warmer and more modulatable than other sampled-only drum boxes.
