The Midi Captain STD + Kemper player demo 

...but not as strange as the "Mvave Chocolate" midi control pedal. Who on earth comes up with these names?😁

All i can report is that i followed the guide given and it updated ok. Took around 10 minutes (and ive updated twice so far) Its a case of deleting most (not all- we're told to keep the "license" folder intact) of the files on the device and pasting in the new ones, simply a drag-n-drop task as the device appears as an attached external drive. As suggested, make a back-up of the files that come with the device before you do anything else. I used windows 10 so cant comment on the mac.

I haven't done any updating, so can't comment from that point of view. But I did find a document on the PaintAudio website called "MIDI_Captain_Serials_Recovery" which is purportedly info for recovery of a bricked unit. I haven't used the document, so I can't say how effective it is or isn't.

Note this does not boost the value by +3dB but rather sets the rig-volume value to +3dB therefore the amount of change will be dependant on the initial value. Mine are stored as 0dB by default so there is a +3dB change To set rig volume to +3dB, you will need to send NRPN parameter 513 to value of 10255. This can be achieves with these midi CC commands; CC99=4 CC98=1 CC6=80 CC38=0 if you want to set rig-volume to 0dB send this midi data: CC99=4 CC98=1 CC6=64 CC38=0

Not to my knowledge. The Kemper remote uses an ethernet connection which the player does not have. A standard midi controller would be the option with the addition of a USB-to-MIDI adapter, like this: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-BVFuOkYalKA.htmlsi=r8vKutExvhm70eRj&t=303
