во первых в окне арранж есть сверху слева qua: выделяешь мышкой ноты, нажимаешь на qua, выбираешь квантайз. во вторых если 2 раза кликнуть на qua появится дополнительное окошко с настройками. в третьих, можно использовать готовые dna groove templates от сторонних производителей (я их видел в инете и в кейкволке вроде) или сам создаешь на основе миди трека в окне арранж. в хелпе лоджика об этом написано. еще как то можно через transform, но я не знаю...
(Creating Groove Templates
Arrange Window > Groove > Creating Groove Templates
Instead of quantizing the notes to one of the preset grids, you can create new ones based on the rhythms in other sequences. These are referred to as "groove templates". Groove templates make it possible to capture the small timing deviations which give a sequence its "feel", and apply them to other sequences.
Creating Your Own Quantization Template (Groove)
The function Options > Groove Templates > Make Groove Template transforms the exact timing of the notes in the selected sequence into a quantization template. It then appears in the flip menu of the Qua parameter (in the Sequence Parameter box), with the name of the sequence on which it is based. It can be used on any other sequence, in exactly the same way as the rest of the items in the Quantize flip menu.
In general, two-bar model sequences work particularly well for this function, but you can use sequences of any length. Make sure that the model sequence actually contains a note at every desired quantization value.)
