It is best to think of the Polaris in terms of 'instruments.'

By default, there is one instrument created for the 'main' patch.

If there is a 'link', then there is another instrument created for it.

Each instrument normally resides on its own MIDI channel.

So - let's say (for instance) that you have a 'main' patch of A-1 and a
'link' patch of B-1 - and you're set up with 'link unison' (so that
whenever you play from the local Polaris keyboard you hear both A-1 and
B-1 play.

Let's also assume (for instance) that you have the Polaris set up for a
MIDI base channel of 1.

If you were to look at the MIDI stream from the Polaris you'd monintally
see data on MIDI Channel 1 (for the 'main' patch instrument) and data on
MIDI Channel 2 (for the 'link' patch instrument).

If you were to play the Polaris - record the MIDI data just like that -
and then play it back to the Polaris - then you'd get exactly what you'd
played. Namely you'd record data on MIDI Channel 1 and MIDI Channel 2.
When you play that back to the Polaris - the Polaris will play the 'main
instrument' on MIDI Channel 1 and the link instrument on MIDI Channel
2 - and you'll hear two patches sound (because you are actually playing
two different instruments at the same time, via MIDI).

Are you experiencing a difficulty in having that sort of behaviour
occur - or are you trying to have it so that you have an external
keyboard send data on _one_ MIDI channel but have the Polaris internally
use that to play _both_ the main and link patches/instruments at the
same time?
