I VERY MUCH hope one day GFI implements a FW update for the Duophony, to allow users to flip the loops order in Series configuration. This will make Duophony the uber-ultimate effect loop switcher/mixer/blender on the market. This is VERY important to be able to change the loops order. I hope there are no technical hardware limitations to implement this.

Awesome pedal, nice work gfi system'...

Awesome piece of equiptment. Ordering mine!

I have a couple questions.
- Will you be updating the firmware in the future to include a random slope LFO waveshape?
- Would it be possible to update the pedal to work completely independently on L/R channels? Specifically with LFO control in mind. My ideal scenario would be hooking 2 stereo effects up together, then randomly panning mix between them on both l/r independently. Thus you get random panning that is not syncd together on L/R (going the same speed would be fine).

what happens if I were to put this in a parallel effects loop in an amp?

[federicouffreduzzi]

Hi there! Is gain on send or on return? Can i leave one loop pedal in Y, a recorded loop for example on my Boss RC.1, and take off the channel? Is possible to have trails when a channel is muted, or in general does each channel have trails? Thanks!

[natsume]

Such a great pedal!
In wet/dry/wet, can this be used with an expression pedal or something to mix a dry signal with a wet, or send a wet effect to a dry one?
Image like wet/dry/wet to wet/mix/wet or mix/dry/mix.

I love this pedal!! Can you add a link to the firmware update page please? Thanks.

Question about stereo panning - say you hard pan Loop X to the right and Loop Y to the left, can you set up the LFO to move the two loops back and forth across the stereo field? So, Loop X goes "R -> L -> R -> .." and Loop Y goes "L -> R -> L -> .."?

[qiuz]

ahh, SO close to what I need for my application. any chance this will ever be able to blend a small amount of the X return into the Y loop while in parallel mode? my goal is to have 100% wet signal for W/D/W with reverb on the repeats of delay.

[randym]

Will this work for stereo.? 2 amps. And can you only split 2 pedals at a time? Ty!!

[dscapes]

Is it possible to add a variable low pass filter in a future update for us bass players ?

[lachlanplache]

Is there a way to have independent control of the level of each loop? For instance, if I want the mix of loop x to be 60% and loop y to be 85%, is that possible?

[teedzay]

is it necessary to use two or more amps or can this still be useful in a one amp setup?

[Banoffeeee]

can it do Y + X too in series through the pedal or need to repatch the pedal??

If this is what you’re doing with line mixers then just imagine what you could produce if you put your minds into a midi loop switcher…
