@Funk:
I used to work for M-Audio some years back and had a Fast Track Ultra 8R for a while, so I know that one. I don't have it anymore, but I'm using the breakout cable for S/PDIF+MIDI that came with the 8R, on my HDR for the MIDI connection and that works. So, I can confirm that at least the MIDI pinout is compatible between the D8B/HDR and the 8R.
But this also means that the D8B's original MIDI adapter will NOT work for S/PDIF on the 8R (b/c it doesn't have RCA connectors for S/PDIF), but it would work for MIDI (if there's enough room around it to fit that odd D8B MIDI adapter).
In any case, the pinout should be pretty standardized, since I ran across the MIDI pin-out compatibility by accident. A MIDI+S/PDIF breakout cable from another device would probably also work.
...and as for recording into Logic vs. Cubase, etc. The sound quality will be the same no matter what program you use to record a signal from a digital input. So, if you hate Cubase, maybe just use a simple stereo sample editor to record your mix with... even the free Audacity would do. Easier to navigate than a full DAW.
I don't recall if the 8R required that you manually set the audio interface to clock to the word clock signal that is part of the incoming S/PDIF signal. If not, you may need to go to the 8R's control panel (while no audio app is open, or at least not streaming audio), and change the clock to sync to the S/PDIF input (otherwise you might get weird clicks and dropouts in the digital recording). But you probably already know all this.
As for the step-by-step for Keny, on how to record a mix from the D8B - a couple of thoughts:
Since the analog days, you bring signals into a mixing desk and route them to FX etc. from there (and then bring them back to the mixing desk in real-time), and set the pan for each channel and the levels, etc. The point of a mixing desk is, that it sums the many audio signals that go into it, down to a single stereo signal that is sent to a stereo output (people who listen to the music you mix, will later listen to what came out of the stereo output of your mixer, on their "stereo system" (albeit usually after a separate "Mastering" step, where the stereo signal is processed another time)).
While actively doing the mixing (and/or letting carefully prepared automation do it's thing) you record that single stereo output from your mixer with "something else" in order to end up with a "final mix".
That "something else" is any device that can record a stereo signal. These used to be dedicated "Master Recorders" such as a 2-Track (Stereo) Tape Machine, later DAT (Digital Audio Tape) recorders, but could also be real-time CD-Recorders, like what you're looking to do. If your audio interface has a free stereo input during mixdown (ideally a digital input, so the additional conversion won't degrade the signal), you can also just route the mix from the D8B back to an input on your audio interface, and record it into the same session that you're mixing (mute that track, or you'll create a feedback loop that will be recorded into your final mix).
You CAN use a CD-Recorder as the final Master Recorder, but it's usually preferable nowadays, to have a stereo audio-file on the computer, for a few reasons;
- CDs are 16-Bit. This means a significantly lower dynamic range than the 24-bit on the D8B and modern audio interfaces deliver (i.e. quiet sections disappear in background noise... "maximum loud" is the same maximum between 16-bit and 24-bit, since digital maximum is always "0 dB digital").
It makes sense to stay with 24-bit through the mastering step (i.e. processing of your stereo mix AFTER you're done with it), and only dither down to 16-Bit at the end of the Mastering process (retaining better signal quality during mastering-processing, and thus resulting in more accurate/detailed digital calculations) - IF (big IF) the end-product is intended to go on CD (...that's not the case for all productions nowadays - some stuff is produced straight for the internet/streaming).
If intended for CD, I'd convert my 44.1/24-bit file directly to the target format (e.g. MP3 for an online release) while the file is still in 24-Bit. Long story short, a CD-recorder as a master recorder is sub-par by today's standards, because of the lower bit depth. I'd get rid of it - it won't add anything good, but will take quality away, compared to what's possible with the rest of the equipment you have.
- You have to rip the CD back in to get an audio file that can be processed in the computer. As mentioned in my response to Funk, this "should" deliver results that are not discernible from how it sounds like when playing the CD back, but there definitely IS a potential that there are errors when ripping the CD back in (...and if you'd analyze the 1s and 0s on the CD vs. what's been ripped back in, there'd likely be numerous minor errors that you can't hear, but that are present nonetheless... already reason enough NOT to use a CD recorder as your master recorder anymore, IMO. It used to make sense when Mastering studios asked for CDs (or DATs), but that's no longer the preferred format (...unless your Mastering engineer lives behind the moon, somewhere).
- CDs can get scratched, which would result in more serious (i.e. audible) errors when trying to read the audio file back in later, such as for getting it re-mastered. So, CDs also aren't really a good format for archiving audio, IMO (...and some of the very early CDs I burned with a single-speed burner back in the mid-90s, have their metal foil lifting off or disintegrating... so, CD-Rs can become useless after 25-30 years or so).
And a little side-story: I still shiver, when remembering how many years back, I handed the CD with the final mix of an album to a musician after days of long recording sessions, and the first thing he did was to excitedly open the CD case and spin the CD around in it, audibly scratching it against the plastic in the case... aaaaaaaarrrgh!!! Even little maneuvers like that, can create tiny scratches on the CD, that can register as digital errors... definitely not what you want for your duplication master.
Long story short, unless you have a very specific reason why you want to use a CD-Recorder as your master recorder, I'd recommend to forget about that, and record the digital output of your D8B, back into a digital input on an audio interface, and make sure you're recording your stereo master to your computer at 24-bit. You'll get BETTER quality and fewer (or no) digital errors when bypassing the whole CD-Recorder step, and going straight back into a digital input on an audio interface or master recorder that can do 24-bit).
As for the steps to follow, I'll try bullets:
1. Connect a 75 Ohm S/PDIF cable (not a regular RCA audio cable) to the S/PDIF output on the D8B
2. Connect the other end of the 75 Ohm S/PDIF cable to the S/PDIF input on your audio interface (or Master Recorder)
3. I'd recommend to set your multi-track recording medium (Audio Interface/Software or HDR or other multi-track recorder) to 24-bit (!!!) and 44.1 kHz from the moment you begin recording the first audio track, unless you're producing music for video. (44.1 kHz is the music CD sample rate - if you want to produce for CD, it's best to start out with recording in 44.1 kHz as well. The 48 kHz option is meant for audio for video, since that's at 48 kHz and matches up better to common video frame rates. The minimal quality improvement of the "higher sample rate" at 48 kHz when producing for CD, is more than undone, by the quantization noise that is inevitable when resampling/dithering the signal down from 48 to 44.1 kHz (and from 24-bit to 16-bit), as is necessary for audio CDs. So, you're making the audio quality WORSE, by starting with the higher sample rate of 48 kHz if producing for CD. Just stay with 44.1 from the get-go!).
4. If recording the final mix on your master recorder (e.g. audio interface/software, DAT recorder or CD-Burner, etc.) via a digital connection (strongly recommended), then make sure to sync the master recorder to the word clock signal received on its S/PDIF input port (i.e. the D8B is set to clock MASTER, and the computer (or master recorder) is set to clock SLAVE - that is, unless you're using a separate master clock generator (Big Ben, Aardvark, Lucid, etc.) - then everything except for the Master Clock Generator would be set to SLAVE.
5. Make all the desired pan and level settings on the D8B, route all the signals the way you want them... set the FX, EQs etc. on the D8B and prepare any automation you want to use.
7. Hit record on the master recorder
8. Hit play on your multi-track recorder and make real-time adjustments (i.e. do the mixing) on the D8B and external FX units that are in the signal chain, while the signal passes through the D8B and into your master recorder, where it is being recorded.
9. When done, press stop on the master recorder (and if using a computer, save the resulting audio file).
If you're unclear about any particular step, I can try to clarify further. But in a nutshell, the above should be what you do to mix your audio and get a resulting master recording.
I hope this helps... best of luck!
