Midi clock sync issues

[flop54]

Hello

 

I use midi CC and PC to change preset and snapshot and I use midi clock to synchronise too.

 

When I only use PC and CC it works.

When I only use midi Clock it works.

 

But when i use twice together. The helix executes only three message (for example one PC and 2 CC) after that he seems to ignore it.

I have check the midi message (with bome send DX) and all the message are sending.

 

My Soft is reaper. I want to test with another soft.

 

Who can do this test for me?

 

Thanks

I make a test so if i use the usb connexion (without audio interface) it works but not with my audio interface with midi. Perhaps the problems is my interface...
