Hello, It is actually possible to modify the firmware of a Zoom device and then install FX from different Zoom devices on it. I have written about this here: https://tonelib.net/forums/threads/how-to-install-other-zoom-fx-on-your-zoom-device-awesome.5657/ At the moment ToneLib-Zoom does not see these new and non native FX so they can not be edited with the ToneLib-Zoom editor. I guess the editor just checks which device is hooked up and displays the FX that should be normally on the device, but does not check if there are other FX installed. It would be awesome if this can be somehow addressed, so that people with a modified device could also edit all the FX they really have on their device via the ToneLib-Zoom editor. Thanks for your consideration!
