Here the part of the manual : 29.3.7 Fixed Length Recording
I cant experience that "Phrase Sync". I really dont understand what is that feature. I have tried to test it but my ableton doenst do what the manual say.By default, starting a recording with Fixed Length enabled will create an empty clip of the selected length, and then begin recording from the beginning of the clip, in accordance with Live’s global launch quantization. If Phrase Sync is enabled, Push treats the chosen length as a musical phrase, and will begin recording from the position in the clip that corresponds to that position within a phrase of that length. For example, with a fixed length of 4 bars and Phrase Sync on, starting a recording when Live’s global transport is at bar 7 will create an empty four bar clip and begin recording at the third bar of that clip.
Is someone can explain to me what is the Phrase Sync on the "fixed Length" bouton on push 2?
