midihub++ was developed for MIDI jam sessions. This compact device provides a MIDI beat clock generator and six MIDI outputs, so that multiple devices can be synchronised to a common MIDI clock. A simple 3 button interface (start/stop, faster, slower) controls the beat clock.
midihub++ also provides a separate MIDI input, which is thru'd to all six outputs. This allows hubs to be chained, or for a hub to be used a general purpose six way MIDI splitter. That's a lot of functionality in such a small, cheap and neat project!
Might be fun for people wanting to slave multiple gbs and piggy enabled gp2xs and end gear... The price is great too!
