Korg tr61 & Mk449c, the sound gets cut?

[miguelg.ancin]

Hello i am using a midi wire for connectiong a mk449c evolution audio controller, for sending midi data to my korg tr61 and generate all the sounds from it. The signal arrives. There is no delay, i play different sounds from the mk449c than from the korgtr61 but again, the sound gets cut. it Seems at random, when i play notes of the mk449 alone, or wit the korgtr61 at same time. ( if it isjust the korg tr61 there is no cut in the sound)
basically it is like a interruption that stops the sound and u haev to repress the keys, if i was holdin my hand on the korg , and i press some notes on the mk449 then the sound can happen to dissapera, after working for some seconds, and the sound the korg was doing is stopped as well. Soemkind of conflict? or, does it haev to something with latency? i need a soundcar? or it has something to do wit the velocity curve? thanks.
