Hi Greg,
I don’t know if my first reply made it or not… Anyway, I’ve used the Edirol R4 Pro in a number of indie film productions and it’s been great.
The quality of the recorded sound is very high, at least when used in the mode I use it — with a Sound Devices 442 mixer.
It’s not ideal for use in a bag like the SD 744T and it’s not quite as robustly built as the SD. Some controls are on the top panel and require a bit of a reach, but of course it’s much less expensive than the Sound Devices recorder.
Having said that, the Edirol is great as a backup for in-camera sound on indie shoots: I’ve found that the camera audio settings can be easily mismanaged and having a pristine recording can save the day. I feed the Edirol with the SD 442’s four direct outputs (line level) into the Edirol’s inputs.
Here are some examples from recent shoots recorded with the Edirol R4 Pro:

If you have any other questions, I’ll be glad to try and answer.
Cheers,
