v7.5.4 (Newest Release) - Acoustic Simulator Rig freezes KPA

  • A couple of days ago, I think 1-2 days after upgrading to the newest release version, I discovered an issue with my KPA rack + remote. I did not try to recreate the issue (since I was playing live), but luckily this happened only during sound check.


    Here's what I did:

    • Booted the KPA in the Performance mode.
    • Played about 5min in the Performance mode.
    • Switched to Browse mode to show my band mates the awesomeness of the Acoustic Simulator. 8)
    • Browsed to the rig containing the Acoustic Simulator.
    • Played 1 song with the Acoustic Simulator rig.
    • Tried to go back to the Performance mode my moving the chicken-head knob.
    • The KPA did not react.
    • There was no reaction on any input command, neither Remote nor any button on the KPA rack unit itself.
    • However, the signal path still worked, I could play with the rig without any issues.
    • Then, I turned the KPA off with the chicken-head knob.
    • Nothing happened (no shutdown procedure).
    • Switched back to Browse.
    • Switched back to "Off".
    • Then, the KPA turned off.
    • Booted again in Performance Mode.
    • Played without issues in Performance Mode.
    • After some hours, I moved back to the Acoustic rig (it was selected directly from before).
    • Played with the Acoustic Simulator rig.
    • Turned the KPA off with normal behaviour.

    Did someone else discover something similar? :)
