How change between sostenuto and sustain?

[Valpurgis]

After updating to 3.925 sending midi cc64 to HX3 expander activates sostenuto. Earlier versions it activated sustain (hold). I cannot find out how to use the HX3-remote app to change back to sustain. Any tips?

I got this answer from Keyboardpartner:

"Sostenuto is enabled/disabled by using the appropriate MIDI CC set. Sets 0 to 6 are with Sustain, sets 7 to 13 are with Sostenuto (marked with a dot in menu display, lower line) ."

Thank very much Carsten!
