Native Instruments MASCHINE MK3 Groove Production Studio (Black) - Manual (Page 383)

Element Description
Stretch This playback engine provides complete independence between
tempo and pitch. With this engine, you can change the tempo of a
loop without changing its pitch, you can change its pitch without
changing its tempo, or you can change both the tempo and pitch
simultaneously. This mode even allows you to automate pitch
changes by entering Events into the Pattern Editor while using Gate
mode. As this mode provides complete tempo and pitch
independence, and also works on polyphonic material, it requires
more CPU power than other Engines.
Formant This playback engine is best suited to pitched (tonal) audio as it
preserves the formant of the sound. By preserving the formant, it
retains the intrinsic character and avoids any shifts in pitch that
would normally result in the undesirable cartoonlike effects on vocals
when they are pitched upwards or downwards.
SOURCE Section
Tempo Set the original tempo of your Sample so that the Audio Plug-in can
accurately play it in sync, no matter what tempo you choose for your
Project. This is useful if MASCHINE has miscalculated the tempo
while importing the Sample. However, be aware that changing
Tempo
during playback could affect the synchronization of your Sample.
To increase
Tempo click and drag upwards. To decrease the Tempo ,
click and drag downwards. Press the [SHIFT] button on your
computer keyboard while dragging to set finer increments.
Length Set the original length of your Sample so that the Audio Plug-in can
accurately play it in sync, no matter what tempo you choose for your
Project. This is useful if MASCHINE has miscalculated the length
while importing the Sample. However, be aware that changing Length
during playback could affect the synchronization of your Sample.
