Anotrher option might be "And this might not work" hard to tell with out all data to hand but you could look at doing away with the 2044 altogether and trying to source a SSM2040 which has the same low pass charicturistis as the 2044 but can be used as high pass band pass band regect and comb filter dependant on the circuit is fitted in to.
Thats if your a bit of a boffin in circuits design.
One day I might try this but not there yet. ;o)

The theory is sound.  I've used two channels on my desk one inverted when passing audio through the MP4s filter to make it High pass.

I was reading the posts that have been going on and I wonder if someone knows how to mod the MP4 to have a wider range of LFO speeds.

I use the switch trick pretty often, but if I could have slow speeds and much faster speeds without it, that would be cool.

Also, I was thinking that eventually I want to get another SSM 2044 and try to add a serial high pass filter and have it use the same filter envelope and key tracking. (although it might be hard to fit 4 more knobs above the filter knobs)

I think if I take the output of the existing lpf and invert it and then mix it with the signal going through the second lpf, then that is a high pass, I believe. So it seems like it would be simple to do, but I might be grossly simplifying the process.

It would be a lot more interesting if I could switch between amp and filter envelopes for the high pass filter and maybe have a switch for VCA gate.
