I updated my reface CS editor (mainly system setting editor) with a Streambyter input rule, so now I can grab the current settings from reface to see, what they are and change them if required. I had to make two parts: one for system settings, which work via sysex parameter changes and the other for sound settings, for which the layout uses simple CC. So the rule needs to translate the incoming bulk dumps in two different ways.
Both settings can be retrieved separately, therefore on both pages there is a dedicated button top right.
Not a big deal, but helpful, when you connect the iPad to the synth, but don´t know if the the values shown in the layout are correct.
Mastertune is not retrieved, since Yamaha´s sysex is too strange here.
