Quantize Mode - In any True Legato instrument, there will be some lag when
playing note-to-note transitions. This is usually compensated for by moving all
notes slightly to the left in the sequencer, or by using a track pre-delay. The
problem with most legato libraries is that the timings of each note are
inconsistent; the first note in a phrase will sound immediately, while subsequent
notes will be delayed. The Quantize Mode tackles this problem by calculating the
legato lag time, and applying the same delay to non-legato samples. This means
you can quantize a performance, shift the MIDI to the left, and the timings of each
note will be consistent.
手册里有这一段，大概意思是真实的连奏音符之间是有延迟的，要在宿主加延迟补偿。激活Quantize Mode可以看到需要补偿的时长。这个用键盘弹连奏的时候好膈应，慢半拍。
