Seems that Ubermap works OK on 9.1.7 (thought it was broken, spent half an hour debugging, then realised I forgot to set Ignore = False in my device config
The one thing I will mention is that because Ubermap is based on files extracted from an earlier 9.1.x, there's a chance that any fixes Ableton make to the Push mappings (doesn't seem like they've done much for a while mind
Hopefully I'll manage to add some new features to Ubermap soon... but for now I must focus on actually making some music!
Cheers,
Tom
