Midi jitter on AL88-C + Cubase 8 (OSX 10.9.5 and WIN7

[Sandrow]

Hi all there.

I've bought an AL88-C for my DAW, after struggling with MIDI over USB jitter problems.

MIDI FROM USB TEST:
A simple 4/4 beat sent via MIDI OUT to MIDI IN (30cm MIDI cable) and recorded back on a new track.

As you can see, both position and leght of notes is totally wrong.

MIDI FROM COPPELAN TEST:
Same beat, same test.

This happens on both Win7 64bits and MAC OSX 10.9.5 and on Cubase 5, Cubase 8 LE, Logic 10.

Motherboard: Gigabyte Z77 D3H
CPU Intel i5 3.4GHz
Ethernet card : Qualcomm Atheros AR8161 PCI Express Gigabit Ethernet
AL88-C is the only device connected to the ethernet port ( no nternet or switch/hub)

Am i doing something wrong?

Thanks a lot.

Sandrow,

We have no idea what causes the problem you report.
It is something we not encountered yet.

However, we noticed in your last screenshot that you have no interface selected for CopperLan.
You have to select one for proper functioning.
