USB sysex issues

[fgeorgy]

Hi,

I work a lot with SysEx, mainly because I develop editors for various MIDI devices.

I have my MRCC connected to my Mac through the PC USB port and 3 devices connected through the A, B and C USB ports. The devices are:
- Nektar Pacer 
- Waldorf Blofeld
- ASM Hydrasynth

No matter what I try, I can't get sysex messages being sent/received between my Mac and these devices. All other MIDI messages (CC, PC, Notes) go through fine. I checked my setup several times. I also checked that I do not have any filters or other configuration that could be the cause of this problem. I even tried with different cables!


If I connect these devices directly to my Mac, then no problem at all.


I also have a few devices that I don't have a problem with and can exchange messages with without any problem: Arturia Microfreak, Meris pedals.

What is the status of the sysex support in MRCC? Are there any limitations (message length, timing, ...) ?


I really would like to use the MRCC to connect all my hardware. But if sysex support is limited, I think I'll need to find another solution.

Thanks for any help!
