Help WK7600 midi controller

[Silvano Silva]

Help!
WK7600 continues with crashes on the same using as a controller.
The exchange of sounds in WK7600 when using the saved registration generates choking in style and this has been shown here.
Today I did a test with WK7600 as midi controller and addressing the kontakt in midi 1 instrument bank channels.
10 midi drum
11 midi bass
12 midi guitar chord
midi 13 pad

As kontakt you can create a database of specific instruments for the channel used.
I put 4 sounds and made the switch to program change where each keyboard instrument means a bank and number.
Such exchange of instruments on 1 channel will not affect the other channels naturally.
The problem started when the style chokes when it makes the exchange of sounds by registration. (RegFlatAcmp active on)
The same problem exists with the keyboard sound happens to midi controller.
Has anyone played this same problem in their instruments WK7600 / CTK7200?
And if ever found any solution please put here.
