Yes, I use 4 MOTU MIDI Express XT USB to connect all my synth to my Cirklon and computer. It works very well except between the Express XT and Ableton Live on Windows 7 (on OSX everything works perfectly). And that won’t change because I’m the only one who reported the problem to both Ableton and MOTU, so they obviously think I have a problem with my config, but I don’t because proceed many many tests with many different computers.
So except that, they work very well in standalone mode to route the MIDI channels and mute message types I programmed with the computer.
Also, yes you can’t choose notes and assign them individually to MIDI channels.
The Elektron sequencer is enough for me and I don’t want to use my Cirklon to sequence it. But they are still not fully compatible… Yes, we will have to wait until Elektron makes a proper pattern change when their units receive a MIDI pgm change. It doesn’t work fully properly between their own machines (pattern change: direct jump) ! Colin, the maker of the Cirklon, is also thinking of a possibility to correct that on its side, which he thinks more appropriate to have something to do on that than Elektron, because it would be more easy to do for the MIDI master on the channel.
