Latronic Notron.
These things are rare, still sought after, and no other product has been made since this one that is simmilar. I think it would be ideal to build a clone using MidiBox hardware and then program the brains using Max/Msp.
Is there something better than this out there?
I would really like to get my hands on a Notron to try it and reverse engineer it. In the meantime I guess I must study the manual…
cheers,

Stuff MAX… Not much point in a hardware sequencer if it needs a PC to run… might as well get a touchscreen for the PC and save some big bucks 
Try this: http://www.midibox.org/dokuwiki/doku.php?id=midibox_sequencer_vx
Edit: Oh the latest pre-alpha versions include the much requested ability to have conditional events, for example, when step 15 of track 2 is played, this should trigger track 3 to play, etc
Oh and don’t forget about the internal feedback on seqv3!
