Interesting you have a photo of the DSI Tempest on there.
I'm a Tempest owner.
Not knocking the potential of the machine, but would you believe that after a couple of years of Tempest being out in the wild, there are still fundamental problems with its MIDI implementation? Especially relating to MIDI clock synchronisation.
To be fair, we get fairly regular OS updates and direct communications with the developers, but it is ironic that a machine with the Dave Smith name attached to it is in such poor shape with its MIDI implementation.
