Figure 12.3. The Pitch Shifting Section of the Playlist Editor

This section of the Sample Editor allows you to use Rubber Band - a tool that can change the tempo of a sample without changing the sample's pitch (and vice versa) - to tweak your sample.

Note

These options are only available if Rubber Band support was either compiled into Hydrogen or was properly configures in the General tab of the Preferences. After installing Rubber Band you should check if the path to the rubberband cli is configured correctly (see Section 5.1). If neither is the case, all associated widgets will be disabled.

When Sample length to beat is set to off the whole Rubber Band functionality will be disabled.

Sample length to beat: specifies the length of the resulting sample (after Rubber Band was applied to it). After choosing a value other than off the length ratio between the original and the resulting sample will be displayed to the right of the combo box under new sample length. To ease the process of finding a proper value, the checkbox will be highlighted green if the length is more or less the same, yellow if there are larger changes, and red if there are significant changes.

	Tip
	This should be set to the length of the part of the sample between the Start and End marker, expressed in number of beats.

	Note
	The beat length does dependent on the current tempo of the song. If it is changed, the samples need to be recalculated using Rubber Band again. When exporting a song all required recalculations will be done automatically. But while using standard playback the button in the Main Toolbar has to be activated to enable the recalculation of all samples on the fly.

Pitch: specifies the resulting pitch of the sample, expressed in semitones,cent.
Note
This pitch will affect all instances of the sample in addition to the Pitch Shift Parameters in the Instrument Editor and the NoteKey property of each individual note.
Crispness: fine-tunes the processing algorithm used by Rubber Band. It does not affect tempo or pitch, but changes the way the sample sounds.

	Note
	This pitch will affect all instances of the sample in addition to the Pitch Shift Parameters in the Instrument Editor and the NoteKey property of each individual note.
