Hi, yes its the encoders on the middle row of the first page. They call a LUA function (which I think you actually sent to me!? back in October last year) to generate relative control data within a sysex string, to mimic the front panel encoders on the Yamaha A5000.
You can read all about it in the original thread here. It worked fine under v3.5, but under v3.6 it doesn’t.
