I concur with Dreamer. I'd like to add that when styles are initially recorded, that they're typically recorded at the 'software' sequencer's highest midi timing resolution (1,920 ppq +), as this insures capturing all the subtle timing nuances of the original performance. Unfortunately, when these recordings are then converted and played back on 'hardware' sequencers (type included in our arrangers), much of the spark of the original performance can be lost, because many hardware sequencers only support 96 ppq maximum timing resolutions. This effectively quantizes the music down making for a bland sound. The Yamaha PSR2000 was a breakthrough keyboard in that it is the first arranger with a hardware sequencer which supports a high timing resolution (1,920 ppq) similar to the professional level software sequencers out there. A sequencer's timing resolution directly effects the quality & realism (live sound) of a style. I only HOPE that the next generation of arrangers (Yamaha Tyros, Ketron XD9, Technics KN7000, etc) will begin increasing their hardware sequencer timing resolution as well. I look forward to hearing from others on this.
