Getting better with practice. Crossfade goal has been met. To be honest, I haven't had any luck with MIXER, however MIX is working perfectly with a KNOB/REMOTER.
Strangely undocumented module, REMOTER. Also quirky behavior with copy/paste, it will fall off the knob, everytime.
So far the unipolar mode with a negative RANGE will cause the value to go from 100%-zero, as long as default is set at 100%, no problem.
Workaround the copy/paste REMOTER issue is to copy/paste the entire factory algo and rewire ins/outs/menu into a working crossfade sigfile. This is also easier to keep the sigfile in order, top to bottom.
Perhaps I missed something in the programming manual, will again reread for insight. Any help on adding remote control is appreciated. This front panel 'SELECT' shortcut is for the birds because the graphical version of the sigfile has to be sorted everytime MIDI/GET is used, and most of these factory algos are so large and complex. Sorting them…
