reViSiT

reViSiT was a promising project in that there is a gap in the tracker market with regards to MIDI control. reViSiT is kind of Redux for midi, but sadly, development appears to have stopped a few years ago and it's still a bit clunky to use. The current version is still available on the website and does work fine though. In all seriousness however I don't see why you would not just use Renoise (unless, like me, you just have a thing for trackers of any kind).
