I bought a Midjay Plus Unit a month ago.
I upgraded it to the last version proposed on Ketron's website (5.2c).
One of the reasons why I chose this unit is for its ability to mix midi/audio a also to manage markers on midifiles.
This is where I meet the problem.

This is how I proceed :
With Mdjay Plus, I integrate a WAV file in a running midifile (in song's intro for example). Then I use an external software to adjust the generated sysex at the right position. I also place some markers (Intro, Verse 1, Chorus 1, etc.). Finally I transfer back the midifile in Midjay.

I play the midifile on Midjay unit. The wav file is correctly launched in Intro (by the way, I note that markers are no more displayed on Midjay Plus screen).
The problem is when I'm I want to go back to Intro by using markers (Edit -> markers - I don't have any pedal switch for the moment):

1 - the WAV file is not launched again, only midi sounds are played (!)
2 - sometimes the Midjay Plus freezes and I can't load any other midifile until I launch the WAV individually to unblock the unit (!)
3 - the Ketron displays the following characters " C'E# " Instead of markers

Point 1 is really frustrating because I bought this unit for using together midi, audio, midi markers and output click.

Has someone experienced the same issue ?
Am I missing something ?
Is there a fix for this problem ?

Thanks to answer me as soon as possible.
