are there any instruments with 5, 6, or 7 channels?

In my continuing quest for multi-guitar and multi-keyboard staves,
I was looking through instruments.xml and I didn't see any instruments with 5, 6, or 7 channels.
Are there any?
Just wondering if I can spare myself having to jump up to the 8 of the Effect and Pad Synthesizers.
I know I can edit instruments.xml but I am trying to avoid doing that, thanks.
