parameter 897 is PRESET_SELECT. -1 is the edit buffer.
parameter 1027 is PRESET_ARP_PATTERN.

I don't have a controller set up to send a stream of sysex, but if I did, to test I would:
1. Select a preexisting arp pattern on the front panel.
2. Via sysex set parameter 897 to -1.
3. Via sysex, send data to parameter 1027.

I am not sure this will let you change patterns on the fly, but this is the first thing I would test to give it a try.

If it works, I would next try changing specific arp presets active on different channels.  And if this works (not sure that it will, but who knows), bear in mind that you just might be changing the preset in memory. So, make sure you test this on backup copies of your presets.

If I get a chance, I will try to simulate this with a sequencer.
