Nora is a powerful and flexible pattern based arpeggiator / phrase sequencer in plugin format that assists you while creating melodies, without sacricifing your own style or sounding cliché. Its full contextual interface allows the creation of solo melodies, rhythmic basslines or stabs instantly. It may be used in both live and offline environment.

Nora employs the workflow of a DAW for a creative, simple and quick edition with a complete integration among the modules. Nora can be sequenced by either a linear manner or by patterns triggered by MIDI.

Thanks to its polyphonic piano-roll technology and its real-time effects, Nora gives the user complete control over the arpeggiator pattern (note-length, overlapping notes/chords, velocities, spaces between notes, etc.)

The engine has been re-designed from scratch to offer precision at sample-level. This way, Nora produces an output that is loyal to the input, without perceptible latency. Moreover, it supports two operation modes: "Free", a mode in which output notes are always in line with input chords, and "Static", in which input chords are adapted to the notes of Nora, resulting in smoother changes.

Nora supports up to eight simultaneous tracks, each of them with an arpeggiator engine and individual settings, like MIDI routing.

One of the best arpeggiators out there. Lots of features and fairly easy to use. Great randomizer and mutator functions.

Would be nice to have an easy option to apply swing.
