Key features:
* Stretch or compress any MIDI signal
* Create swing and shuffle rhythms
* Create pre-generator dynamics
* Use tempo rubato
* MIDI filters
* Smart quantization

Take care, it's a pre-release. Some features may be removed or replaced until the release of the final version. New features may be introduces. Work is still in progression. Any ideas are welcome.
