The MOD DUO X has two TRS mono audio outputs. In addition to that, there is the headphone out that can also be used for CV out.
My idea is, it would be great if there was a second pair of audio outs available. For example, I would like to run a stereo guitar signal into a pair of guitar amps and at the same time route a stereo synth signal directly into a PA. Obviously the device does not have a second pair of audio outputs. Do you think you could implement the headphone out to support this scenario?
