I've not heard the e-bank presets (I may see if they are available for download, now that I know of them), but shouldn't it be relatively easy to find out how Roland achieved the "thickness" and "realism" of these patches simply by investigating the settings of the various parameters of the patch (TVA, TVF, effects, etc.)? Or does the architecture of the 2080 differ from the 1080 and XPs (more simultaneous effects or something that could fatten the sound)?
