I'm not sure, but I would suspect that factory programmed 'internal keyboard styles' aren't created on the associated arranger's style pattern hardware sequencer at all, but instead, recorded using a high end sequencer program such as Cakewalk Sonar, Logic Audio, or Cubase, which not only supports the highest midi timing note resolution available, but also includes other elaborate softwre midi recording & processing capabilities not available on a hardware sequencer. When the completed style pattern is subsequently imported into the keyboard, the midi timing resolution is automatically reduced to whatever the maximum ppq midi note resolution supported by that keyboard. - Scott
