I had troubles to replicate the issue first. It seemed to worked just fine. I found it eventually, it is related to the migration from the original config format and the new one. It is fairly easy to fixed.
I will make the acceleration curve steeper to see how it works.
the 3.7 brings a bigger change in how the internal commands are processed (I think we talked about that at the Superbooth). There is now a central event processor and all the IO / API simply inserts a message to the event processor queue. This means that virtually anything that can be done with Lua or UI, can be also done using the MIDI messaging. That means, that adding new MIDI messages to manipulate controls is easy now. But, as v3.7 grew big, I want to make sure it gets out soon without adding more features. I am happy to add new sysex api calls in v3.8.
