Wavestate hangs during playing

[NEWJEM]

Hi everyone,

I have bought the wavestate one week ago and installed the last firmware update from Korg website (2.1.1)
Yesterday I tried some preset and with one of them I crashed two times the wavestate. It hanged on the same chord. So unable to change anything with a button... Sound stopped and it stayed on. The only thing I could do is maintaining the on/off swift during some seconds so it turned off directly with no messages on the screen. Then I could turned it on again.
The preset with I got the issue is the same :"Litmus Test Question 55"

This can be easily reproducible
Select the sound in perform. Then click on octave + one time
Then play chords slowly (5 seconds by chords) the hang should happen in less than 1 minute.

Did you experiment such behaviour?
Thanks
JEM
