Ciao a tutti, qualcuno sa dirmi la differenza tra SLICING - RHYTMIC - POLIPHONIC ecc?
Grazie

Spiegazione molto chiara la trovi qui. Direttamente sul manuale.

etting to Know the Flex Modes
Flex modes determine how the audio material is processed, and each flex mode is best suited to a specific type of audio material. Rhythmic, Monophonic, and Polyphonic flex modes are named based on the type of material they are best suited for. Slicing, Tempophone, and Speed are so named to indicate the specialized process they apply. When you choose one of these flex modes from the Flex Mode pop-up menu, the parameters for that flex mode appear below it in the Inspector’s Track Parameter box. You adjust these parameters by clicking a checkbox or by dragging the value vertically.


You can choose from the following flex modes, and their respective parameters, for track- and region-based flex time editing in Logic Pro:

Off
Disables all flex time editing properties on the audio track.
Note: If an audio track in this flex mode contains Apple Loops, they will follow the project tempo unless the Follow Tempo checkbox is deselected in the Region Parameter box.

Slicing
Slices the audio material at transient markers and plays each slice at its original speed—in other words, no time compression or expansion is ever applied to the audio. Slicing is a good choice for drums and percussion.
Fill Gaps: Extends the release phase of slices in passages up to the next slice—otherwise, gaps left between slices are audible in time-expanded passages.
Decay: Sets a time in seconds for the artificial decay phase. This parameter has a range of 0.10 seconds to inf(inite). The maximum setting of “inf” keeps an infinite sustain.
Slice Length: Shortens each slice by a percentage value. Shortening slices can be helpful for removing unwanted pre-attack sounds from the following slice, or to create a gated effect.

Rhythmic
The Rhythmic flex mode is most suitable for non-monophonic material, such as rhythmic guitars, keyboard parts, and Apple Loops.
Loop Length: Sets the length of the looped section at the end of a slice that is used for time expansion.
Decay: Defines a decay value for the looped area, with a range from 0.1 seconds to infinity.
Loop Offset: Allows you to move the looped area up to 100 ms to the left, preventing pre-attack sounds from the following transient to appear in the looped and crossfaded area.

Monophonic
Time-stretches material in real time, delivering high sonic quality. The Monophonic flex mode is good for solo vocals and monophonic solo instruments—melody and bass lines, for example.
Note: When you use this flex mode, your recording should be relatively dry, without audible reverberation. Otherwise you may want to try using Polyphonic.
Percussive: Preserves the area around transient markers. If selected, allows better timing for all kinds of percussive monophonic tonal material, such as plucked strings (guitar, bass) or tonal percussion. If unselected, prevents glitches on transient markers in nonpercussive tonal material, such as bowed strings or wind instruments.

Polyphonic
The Polyphonic flex mode time-stretches material based on a process called phase vocoding. It is the most CPU intensive of all the flex modes, but it delivers high sonic quality with suitable polyphonic material. It is recommended for complex polyphonic material and is good for all kinds of chords—such as guitar, piano, and choir—and also complex mixes.
Complex: Enables internal transients in the audio material.




Tempophone
The Tempophone flex mode emulates the effect of an historic tape-based time-stretching device known as a tempophone, and results in a mechanical sound with many artifacts similar to those produced with granular synthesis techniques. It is intended to be used creatively for special effects.
Grain Size: Defines the size of the grains that are represented in the original speed to create the time expansion. The Grain Size flex mode produces artifacts similar to ring modulation, where grain size determines the modulation frequency. It has a range of 0.10 to 500.00.
Crossfade: Adjusts the crossfade length from 0.00, which produces hard artifacts, to the full grain length of 1.00, which tends to sound softer.

Speed
Time-stretches material by playing the source material faster or slower, including pitch change. Because of the pitch shifting, this flex mode is mainly useful for percussive material, but use it on all material for interesting creative effects.
