Technically speaking, I don't think this functionality exists but Amos would likely be the only one to tell us for sure.
But Polychaining and Note priority scheme are two very different things;
Polychaining typically involves note distribution across devices, sometimes as passed on from the prior device in the chain, sometimes as distributed from a 'master' directly to an endpoint.
Little Phatty's latest code has this functionality along with Slim Phatty but Taurus does not, Voyager does not, and minitaur does not (yet). There is no heads up display on Minitaur obviously (part of the charm) so implementing it would require a series of settings 'under the hood'.
However, Low, High, Last note priority is implemented CC#91 (though I personally have not tried it) so in theory, any devices that support this basic mechanism should work just fine with Minitaur. The application is that if you hold two keys on a midi keyboard and both devices are on the same channel, that Minitaur would only play the lower of the two for instance.
There are also 3rd party applications like Mutable instruments MidiPal which a few of the guys here have experience with. If you are in EMEA this is more easily gotten, otherwise International shipping is required. I ordered the 'bare' version and am going to put it behind a panel in my modular. But in essence, it supports a primative round robin Midi note distribution scheme which is exactly what the Dr. ordered.
I'd be interested in playing notes across a few devices through a common envelope structure and filter that way you have zero worry about varience between filters on each note; of course it's only useful for full on chords since the envelope would retriger each time. But if you have synths that are similar in design and tuned similarly like 4 x SEMs, you can easily play a low note and 3 high notes, etc.
More information than you asked for I'm sure, but i think I'm famous around here for that. Here is the link for the Mutable instruments product:
http://mutable-instruments.net/midipal/ have a look at the manual also and the "Dispatcher" app. It's an amazing device and well worth the 69+ Euro.
