In the last ~10-12 years, I have primarily used styles. Years ago, I played keys in a 6 pc band so the "styles" were played the rhythm section of the band! :-) But these days, it's mostly with styles (often modified in various ways).

When I play my organ (Hauptwerk 'virtual organ'), I play just organ, manuals and pedals. I miss having pedals for certain kinds of non-style-oriented music on keyboards, but I kind of grew tired of carrying pedals and setting them up with everything else. So ~90% of my keyboard playing is with Styles, and ~10% is with no style (just playing piano, or strings, or orchestral, etc.). I have tried "for fun" playing along to MP3s and MIDI files, but generally it's not for me I find ...
