Integra SN-Synth, 4 types of LPF?

[ScottRS101]

In the Integra Parameter Guide, the following filters are listed for the SN Synth.

BYPASS, LPF1, LPF2, LPF3, LPF4, HPF, BPF, PKG

This is different than the Jupiter which only lists a single LPF type.

I can't find any further info on this. Are these different filter models? I note that the same 4 LPF types are listed for the FA series.

Basically these are the new filter models added with Jupiter 80 OS 2.

LPF 1: Jupiter-80 (held over from Version 1)
LPF 2: Jupiter-8
LPF 3: MiniMoog
LPF 4: Prophet 5
