The ELECTRIBE MX is a major step up in power and quality from the original ElecTribe series of dance music sequencer/synthesizers from Korg. The EMX-1 comes in a sturdy metal chassis with larger back-lit LCD display, expanded memory, voices & multitimbrality, more real-time controllers and vacuum tubes! Effects, Motion Sequencing, and Pattern length have also been expanded. And a new ribbon controller and slider have been added, providing a remarkable realtime interface for accessing the powerful arpeggiator.Starting with its synth engine, the EMX-1 uses MMT synthesis (Multi Modeling Technology) which offers sixteen different oscillator algorithms, providing powerful analog synthesis models as well as sophisticated additive, PCM, chord, unison, combination, wave shaping, formant models and more. The built-in PCM library includes 207 drum PCM sounds and 76 synth PCM sounds ready for immediate use, ranging from powerful kicks and snares through amazingly unique organic sounds. External audio signals can be manipulated using the Comb Filter oscillator algorithm, and then further processed by the internal filter and effects. COMES WITH PSU and Stepdown for PSU - And Manual!
