It's cyclic alright as it's far too regular.

I'm waiting to hear from the 1080's owner to see if he's been in touch with Roland yet.
I sent him instructions on how to find it's system version as I have a feeling he has an early 1080.
The band I normally work with has a 1080 in the keybaord rack, and it doesn't make this noise.
Myself, I've a 2080, and it too acts as it should.

I yet you know what the results are as so as I know myself.
