Como aumenar el tiempo de un sample en FL?

Manual FL Studio escribió:

Resample - Standard pitch shifting that varies sample length to change pitch.
Pro default - The 'Default' mode is designed to work with a wide range of input signals, try the other modes only if 'Default' fails to give the result you need.
Pro transient - For certain sounds, transients are crucial to the overall result (percussion, for example). This mode attempts to preserve the transients in the input signal.
Transient - A lower CPU usage transient-preserving stretch method which corresponds to the Elastique time-stretching default mode. It is provided as an alternative to the 'Pro Transient' mode.
Tonal - Provides higher quality for input signals with a focus on tonal (pitched) elements.
Monophonic - Specialized for monophonic input signals (such as vocals or solo instruments) and should give the best results for these type of signals. The tonal quality is achieved through formant preservation.
Speech - Optimized for speech. (For singing, use the 'Monophonic' mode).
