Low Pass Filter Stereo In/Out

[fogdigger]

Hi Guys,

I'm pretty torn trying to find a solution to having a low pass filter like the Moog but with stereo in and outs for my keyboard. I've been currently trying with my Strymon Mobius pedal using its filter, but there is no solution to make it expression pedal controllable, ie. Sweeping from low to high manually.

Has anyone made a solution to this? Are there any alternative pedals which have stereo in and outs. Is it possible to Mod the Moog LPF? Or is the only solution to have 2?

Thanks for your help!

I copied this from the Strymon Mobius Manual:

Envelope filtering and traditional Wah effects (with an Expression pedal) are available.

TIPS & TRICKS: With the MODE set to WAH and the DEPTH knob at minimum, attach an expression pedal to control the F MID param and you’ve got a great sounding wah effect with adjustable Q (resonance).

I don't have a Mobius in my office at the moment, but I expect that the trick will work for all of the filter types available.

Here are some other Stereo Filters that can be controlled via an Expression pedal:

ELECTRIX PRO FILTER FACTORY

(Long out of production - I have one of these.)

SHERMAN FILTER BANK 2x2

(It'd be awesome to have one of these.)

Good solutions from Dan.

Buy two Moog MF-101s?

If its 2 Moog LFO whats the best way to sync them so its controllable by one expression pedal?

They're the cheapest moogerfoogers to get 2nd hand anyway.

Also what about the Moog MF Drive? 2 of those?

If you got two MF-101's, you would likely need a CP-251, or other CV mixer with a mult section to split the expression pedal CV. That adds some cost to the equation, though. You could maybe split the expression pedal with a Y cable, but you would also split the CV value, which may have undesired effect.

The Akai MFC42 is pretty awesome for stereo filtering, although the envelope cycles only and cannot be triggered by dynamics. It doesn't sound the same as an MF-101 though.

Your keyboard has no filter at all? Typically filters are used mono, before an stereo effects, but that also depends on the sound you are going for. I've recorded both ways for sure.
