i’ve got some timing issues 
i run edirol fa101 audio interface with 7 msec output buffer, playing some midi stuff on virus and airbase 99.
now when i add some uad-1 effects on a sample-only channel, the whole timing changes.
(eg. when i - just for extremet testing testing - add 10 cambridge eq’s on a single channel, the whole timing between renoise and midi instruments shifts incredibly - basically this is very unstable working basis, not? )
please advice !
