You can choose how Connect Pro changes the pitch and duration of playback of samples, by selecting the Time/Pitch mode, located in the Sample module under the Engine tab.

HQ and HQ+ modes use a high quality, but relatively CPU expensive time stretching algorithm developed by Zplane.
These modes give you independent control over the pitch of a sample, so you can change the pitch without affecting the speed and vice versa.
