You never know, a bad diode or opto-coupler could cause jitter, even if it's very unlikely. I own adapters female to female. I repeat it: I'm not using my USB interface for good reasons. I've got one PCIe and two PCI interface (regarding to a missing cable I only can use one of the PCI interfaces at the moment). Even in the 80s, when computers were capable of "real real-time" (the correct term is "hard real-time") I used several MIDI interfaces when possible. Using one Interface for all could cause issues, even when the computer doesn't produce jitter. A really big issue for Linux is, that there are less coders interested in facts about MIDI jitter and the abilities of musicians. Any comment about MIDI jitter and they call you a troll, asshole etc.. There are just a few coders who don't, a good reason to use JACK2, they listened to users like me and improved JACK2 a lot regarding to MIDI jitter. However, you can't improve MIDI timing for an USB interface. Get rid of USB for MIDI.
