Access Virus KC, Logic Studio & ARP Sync - Please help!!

[Tokyopop]

Im using an Access Virus KC, via an external midi channel in Logic, connect to an AMT8.

When the I play an ARP patch iv created through the midi channel in logic, the ARP pattern doesn't play back. All I get is the single note and sometimes 3 notes of the pattern????

Similarly, when I have the external midi track selected in the arrange page, when I play the keys on the virus, I get the same problem. However if I move the selected track in logic to an audio channel for example, I can strike the keys on the access and hear the arp play back perfectly.

This may be a simple issue, however I cant seem to figure out what the problem is here.

Iv gone through the ARP settings on the Virus & can only find a "send ARP data" function that may relate to this???
