New Features in 3.1 include:
- Support for VST and AU MIDI generators: This means that you can use specialized tools such as harmonizers, note matrices or arpeggiators - things that can "drive" other instruments in Renoise now.
- Improvements to the sampler and DSP sound engines: Completely new, rewritten filter section as well as optional oversampling and bandlimited sample playback. Various Renoise native DSP devices have be improved too.
- More love for Phrases: Phrases (small tracker sequences, which can be triggered via notes from the main sequencer) have become a lot more powerful and streamlined too - when working within the phrase editor, you could describe it as "feeling more like the pattern editor - Renoise's main sequencer". And when working in the pattern editor, you have more options for controlling phrases as well.
- Presets everywhere. And now, libraries too: Renoise 3.1 includes a more powerful preset system. You can now store/recall samples and keyzones as presets too, and the whole preset browsing experience has been improved. Presets also easily can be shared and reused with Redux.
- ... and much more.
