Note: The Grooveshifter relies on perfect matching of the project tempo with the tempo
of the treated recording. Any tempo variations deliver less precise results.
Grooveshifter Source Material Parameters
• Beat and Tonal buttons: Switch between two algorithms, each optimized for different
types of audio material.
• Beat algorithm: Optimized for percussive input material. The Grain Size slider has no
effect when Beat is chosen.
• Tonal algorithm: Optimized for tonal input material. Because this algorithm is based
on granular synthesis, it offers an additional Grain Size slider.
• Grain Size slider and field: Sets the size of the grains—technically-speaking, this
determines the analysis precision. The (default) Auto setting automatically derives a
suitable grain size value from the incoming signal.
Grooveshifter Swing Parameters
• Grid buttons: Determine the beat division used as a timing reference by the algorithm
when analyzing the audio material.
• Choose 1/8 if the audio material contains primarily eighth notes, and choose 1/16 if
it consists mostly of sixteenth notes.
• Swing slider and field: Determines the amount that even beats are delayed. A value of
50% means no swing, which is typical for most pop and rock music styles. The higher
the value, the stronger the swing effect.
• Accent slider and field: Raises or lowers the level of even beats, accentuating them. Such
accents are typical of a variety of rhythmic styles, such as swing or reggae.
