CHAPTER 3
Elastique Time-Stretch & Pitch-Shifting
Approach for dynamic use
Generally any pitch parameters of samplers create pitch-shifting by the speed-up or
slowing-down of the playback tempo of an audio file - so to speak only the playback tempo
is changed and the pitch retains.
„Elastique“ however changes the original pitch of an audio file in real-time and retains the
playback tempo. So as soon as „Elastique“ is activated, the „pitch“ parameter in Engine
automatically switches accordingly - both on the „Mapping“ page and the „Modules“ page.
The Mapping page „pitch“ parameter is qualified for static changes of the pitch, whereas
the „pitch“ parameter on the Modules page is qualified for dynamic pitch changes. You can
create changes of the pitch (destination „pitch“) and of the tempo (destination „tempo“) with
the use of the internal sources, like LFO, Step Modulator, Free Envelope, etc., for example.
Switch to the “Modules” page after the selection of “Elastique” in the “read model” pulldown
menu. Two new buttons “auto tempo” and “formants” are now available:
„auto tempo“: If activated, the current BPM settings for all audio files of the Mapping page
get used - if BPM values are available. In this case any further editing of
the parameters „tempo“ and „pitch“ on the „Modules“ page will be based on
these existing BPM values.
If „auto tempo“ is not activated, all files get processed without the
consideration of their BPM values.
„formants“: (Formanten beibehalten) If activated the formants of the audio file get
preserved during the processing. This option improves the time-stretch
quality.
