There haven't been any updates of Tonelib-Zoom since 4.3.1, so as yet the new MS Plus pedals, the B6, B2-Four, and presumably some guitar pedals are unsupported. Zoom themselves aren't doing anything about this barring an iOS app - will the excellent Tonelib-Zoom be updated to support the new pedals, hopefully with both Android and Windows versions?
It would be awesome if the Zoom B2 four will be supported in Tonelib Zoom! If there are any development activities that I can participate in, please let me know.
