Jeff Larson has released version 1.23 of Mobius.
This release adds full support for "Rate Shifting", which had been released as an experimental feature a few months ago. The new rate shifting algorithm sounds much smoother than the previous one, and you can now use a MIDI keyboard to do rate shifting in chromatic intervals with a single Mobius function binding. Note that rate shifting alters both the pitch and speed of the loop. A later version will add support for Pitch Shifting without changing the speed.
