I'm experiencing some clicks during playback using a tascam us 122 with Nuendo 3 (setup on my signature). The project only contains midi with some vsti's (processor working at 50% according to nuendo meter) I have followed the tascam OS tweak document, some others too, but clicks are still there. Any ideas of how can I workaround this? Is latency a common issue with tascam us 122? I know that is completely different scenario, but on my iBook G4 1GHz, 768MB Ram used to work perfectly with ableton live 4 and cubase 1.6.
