The EPS is just that with clever new features that make it not just a professional studio music production tool, but also a powerful live performance instrument. Its biggest feature is its ability to load new samples while playing the instrument, a feature you'd be lucky to find on current synth/samplers. The EPS is somewhat multitimbral in that you can have 8 instruments on-line one at a time or stacked* and switching between them is as easy as pushing one of the 8 instrument buttons. The 'Patch Select' buttons over the Mod-Wheel allow for on-the-fly patch switching from a spot where your hand is likely to be while performing!
Its unique 13-bit sampler is highly versatile with multiple sample rates to choose from (6.25 to 52kHz). However, higher sample rates mean less polyphony and sample time. Unfortunately sample memory is miniscule at 480 Kb yielding anywhere from 5 to 41 seconds of sample time. Fortunately it is expandable up to 896 Kb (with optional 2x expander) or 2.1 Mb (with optional 4x or 4x+SCSI expanders) allowing as much 167 seconds of sample time. Some of the EPS's goodies include an 8 to 16 track sequencer (which steals its memory space from the same RAM that holds the samples) with quantizing, digital filters that seem like analog and preset template envelope options.
