Mario, the fact that you're using a MIDI hub got me to thinking. Maybe I should look into getting one too. I have a couple of Midisport 2x2s and a Roland adapter, which might work okay, but to be honest, I've had some difficulty getting any of them to work in my DAW. Dunno what the problem is, but I suspect it's a configuration issue. Originally I thought that one of my instruments was defective, but when I had the same problem with another instrument, that indicated to me the problem lies elsewhere. One of these days I'll figure out where that elsewhere is.
That was my thought when you had mentioned your issue.
I'm curious if using multiple midi patch bays is problematic more often then not.
I would think those configuration fur balls would be long addressed/resolved by now.
The 'chaining' of multiple midi patch bays is just another "fuzzy" factor for me.
EDIT: when I'd commented that all midi devices may not be able to be chained for some reason?
My currently chained modules have
1/4" stereo analog Ins & Outs which is how how I chain them up....I've never had luck using the 5pin din outs/thru's to chain my modules.
Manifestation of user ignorance and ability to configure correctly.....absolutely.
I also have a JV880 (not that I actually
need it with what I currently use)that is not in the chain because it does not have 1/4" inputs.
I did give the 5pin din configuration path a try using the midi ins/outs/thru's when I got the JV880 but no luck and much frustration.
But....everything has been working well with my current system now so you won't find me trying to fix a working toaster.
Carry on....
