"Digidesign Midi I/О" in "ProTools 10HD" in "OSX Maverics"
 

When using MIDI interface "Digidesign Midi I/o" MIDI notes in "Pro Tools 10HD" is played unstable. When using any other MIDI interface, everything plays stably. But when using" Digidesign Midi I/o "the notes start to"float". When you connect it to another DAW, it works stably. But "PT10HD" with "Digidesign Midi i/o" in "OSX Maverics" is not stable. Can someone tell me what's going on?

OSX 10.9.5 Maverics, ProTools 10HD, Digidesign Midi i/o.

UPD: Maybe there are MIDI interfaces that AVID recommends for "Pro Tools 10HD"?
