I Currently use LAWP for audio post in a pro environment. MMC works with the digital timepiece. I run Windows, audiowerk 8 (not recommended), digital timepiece, midiman winman 4x4 midi int. I get slight float problems with Logic controlling the digital timepiece via mmc. Since I am syncing to a digital beta machine I just use the digi timepiece to read smpte and have logic follow the mtc from digi timepiece. This proves to be a little bit more stable sync, but isn't as convienient to use Logic as the slave. I will say that either way I am unable to approach sample accurate sync. I am about to use a DSP factory and see if lightening the cpu load will help at all. Hope this helps. Chip
