The GEM Genesys has 8 Style Presets per style to solve this problem. There are 256 preset Styles and 64 User Styles, all with 8 Style Presets (registrations) each. That's 2560 style presets in total.
There are also 1024 Panel Memories that store the selected style, variation, tempo, right hand and left hand sounds, style track sounds, effects routings & mixer settings for live and accompaniment tracks, transpose, vocal processor settings (4 part harmony, effects, volumes) etc.
Oh yeah, each Memory and Style Preset can be named and will be displayed whenever you like.
