Hi,
I think there are a few mistakes in your Google Doc description.
We can discuss it off-line if you like. For instance, the filters are
configured as 4-pole by the way the 3396 chip is designed. The op amp
voltages simply set the resonance and the cutoff frequency.
But I am writing to ask if you have a copy of the Matrix 1000
EPROM image. I'd like to look at the patched code for the bug fixes
and see if the same code is in the Matrix 6/6R.
Thanks,
Bob

Just when you think that you've seen it all: This guy has already figured out how to upgrade the Matrix' filters to Xpander-like flexibility.
There are a couple of flaws, though. First, you'd have to build six PCBs and figure out how to fit them into the M-1000's housing. Second, you'd have to rewrite the firmware - and add some more CV multiplexing. But well.
Still, I think tinkering with the M1000's hardware and firmware is well possible. I've started collecting the basic knowledge in a Google Doc - have a look, and if you'd like to add something, comment.
