No, since I sold my Axe-FX long time ago I would have no way of testing the integration. Mr. Kemper was so kind to offer me a Kemper Profiler free of charge to implement the Kemper specific integration with the FCB1010.

No, the LG2 has a lot of fancy features (like loops and sweeps and a random generator etc etc) which will not be available. TinyBox focuses on sending regular MIDI messages to MIDI and USB. Best way to learn about the feature set is by looking at the editor samples on our website : http://www.tinybox.rocks/tinybox_editor.html
