Sekvens is a sequencer made for live use on stage.
Apart from all regular sequencer functionality it has a couple of features that make this more of an instrument than a sequencer; you can save any state at any time and recall that state with just the push of a button, the saved states will be there the next time you open your project (even if the project crash) so you can bring that epic sequence with you from one gig to another. Map the four triggers to drum pads (or any midi button) for play in real time.
This is an Alpha release with some known bugs. Read the PDF in the download package for more info about known bugs.
