So, I have an HX Stomp that I love. I have it on my board with a BOSS MS-3, and also a Morningstar MC6. I've had some issues with the HX where it 'freezes' - the UI just stops responding altogether, and the right most stomp switch turns a solid blue color, no matter what it was prior to that. The good thing is, the pedal still processes audio while the interface is frozen, but you cannot change anything (patches, snapshots, etc) while in this state - it requires a power cycle to 'reset' things.
This past weekend, I was determined to figure out why this was happening, as it has been happening more frequent lately as I program my board with MIDI messaging. I can freeze my HX without fail over and over again - literally right on booting it - by just having my BOSS MS-3 send MIDI clock data, which I configure the HX to listen for. I've posted a video of this behavior here: https://www.instagram.com/p/B0_WlE8nrNX
In the video, I've just booted everything up, and attempt to send a PC message to the HX from the MC6. I made this video prior to discovering that if I turned off MIDI clock info from the MS-3, that the HX doesn't freeze any longer. But here, you can see it boots, but as soon as I try to change patches, the freezing happens. Again - I can do this over and over again - when MIDI clock is enabled on the BOSS.
I'd prefer to keep MIDI clock enabled, as my tap tempo switch is connected to the BOSS - the MS-3 has no MIDI input, so I have it at the 'top' of the MIDI chain - MS3 -> MC6 -> HX Stomp. I've tried having the HX configured to listen on a specific MIDI channel (6) or Omni, I've tried it with and without the MC6 in the chain, it doesn't matter... it happens every time. I've opened a support request to Line 6, but I'm still waiting to hear back from them on this one.
EDIT : I should also add - I updated to 2.81.0 and performed a factory reset on the device. I've loaded no backup or anything. I also cleared all presets / IRs / settings by booting it up holding all three stomp switches. This was all done prior to creating the video above, as you can see it's an entirely empty patch that I am able to get it to freeze with.
Is anyone else experiencing issues like this? It is maddening. For such an amazing unit, it's discouraging that this is happening.
