I replaced my MC6 MKI with an MC6 MKII today. Nothing else on my pedalboard changed. Shortly after setting up presets, I noticed MIDI PC and CC messages from other presets, in the same bank, were randomly making their way to the Specular Tempus (last MIDI device in the chain). I know they were from other presets because the display on the Specular Tempus would show the other preset names or show Tempo which is sent by my TAP preset (D) only.
This occurred when switching between two presets (pressing buttons B & C) or by pressing the same button multiple times.
My MIDI chain is as follows:
Morningstar MC6 MKII -> Voodoo Lab Hex 6-Loop Audio Switcher -> Specular Tempus.
• It doesn't happen if you take the Voodoo Lab HEX out of the chain
• It doesn't happen with the MKI version of the MC6 (with the Voodoo Lab HEX still in the chain).
• It doesn't happen if another device is used to pass the MIDI, such as a Selah Quartz v2.
• Tried adjusting the switch sensitivity on the MC6 MKII to the least sensitive setting and that didn't make a difference.
I'm hoping there is some information on how the MKI and MKII may be sending these messages differently. Both the MKI and MKII have the latest firmware.
YouTube videos of the MKI and MKII behaviors (as described above) are attached. Also including an example of how the two presets are configured.
