I had no clue what I was doing at the time and still don't but a few weeks ago I hooked the digidesign adat bridge up to the G4, then plugged tracks one through eight into the adat bridge from the HD24. I armed the first 8 tracks in protools then hit record, then hit play on the HD24 and all 8 tracks were recorded, I guess not transferred, into the G4. I saved it under a file name. I closed out of protools, opened protools up again and called the files up, plugged the adat bridge out into the adat card on the Yamaha 02R and hit playback on protools and they all played back. So, they did go there, get recorded and play back. I was able to do that. The only problem was track one which should have been the kick drum came back as a squeal and I was guessing that I had recorded track one at too high a volume. All the rest of the tracks sounded fine. I have not really got back to it since. They have the instructions in the HD24 manual on how to set up a Mac to communicate between the two. There are no instruction on how to actually transfer the files so I will look into that on sweetwater. Thanx.The software. https://ringbreak.dnd.utwente.nl/~mrjb/hd24tools/download.html

The downside of this is the ethernet transfer is insanely slow because the nic card in the HD24 is a few generations old. But since the G4 isn't the computer you use for anything else, it doesn't matter much if it takes a week to transfer everything.
