Reverted back to 3.8.5. I only tried one functionality in ToneLib Zoom 4.0.1, installing a patch from the online community, and it did not work.
I encountered the same issue with ms50-g after upgrading to ToneLib Zoom 4.0.1. "Sound check" worked, but "Load to device" had no effect.
Same problem here. I can download the patches and import them from desktop, but cannot download them directly to the G1Xon. Soundcheck works though. Assuming this isn't going to be fixed in the immediate future, any idea where I can get previous installers from?
+1 here I'm on linux and i think that the problem come from the file extension which is on undercase in the online community (ex: sample.g1xon) and need to be in uppercase ( sample.G1Xon) in Tonelib Zoom.
