Everyone seems to be interested in old-fashioned step sequencers again. SoS just reviewed a CV-to-midi converter which allows ancient sequencers to control and sync to computers, and everyone wants a Latronic Notron - the 90s hardware sequencer that Bjork and Howie B used - now selling for $2,000+. Out today is the snappily named SQ42 - a baffling looking multi-channel sequencer inspired by the hugely desirable Korg SQ10 (above). You can download the demo here.
I haven't had time to play with it, but it looks interesting.
