ProX (newbie) with a MOTU8D (digital only interface). Patching digital effects processors

I use ProX (old fart but newbie here) with a MOTU8D (digital only interface). Setup: acoustic guitar>2 mics>micpres>external A/D converter (Acousence)>AES/EBU>MOTU>USB>Mac.


My goal: I want 2 separate (L+R) guitar tracks, each with 2 send/returns to and from my Quantec Yardstick + TC4000 digital reverbs patched (AES/EBU+SPDIF), to and from the MOTU. The MOTU 8D has 2 AES/EBU + 2 S/PDIF ins/outs (8 channels total) with extensive routing capabilities. Ideally I would like: the 2 dry acoustic tracks with (at least) two I/O sends (simultaneously active) for processing with external hardware, plus (at least) two pairs of stereo tracks for the returns from the reverbs.


I have since been unable to do this, and it seems I can only have one send active at a time. How exactly do I set up the routing matrix for this task inside the MOTU 8D. I have been unable to find any tutorial of the Logic Pro X paired with the MOTU 8D, but I guess this is not a rare combination among Logic users, so my hope would be finding someone who has this setup.


As a newbie here I would very much appreciate your help.

Best from Roma

Ok, I got most of what you said. Right up front... I don't use or know anyone that has or uses the MOTU unit. However, I'm going to make some suggestions... one being, leave your external FX processors out of the mix for right now. Get comfortable with the software first, you have too many variables at this point. Go with me on this we're going to endup using Logic's "Space Designer" reverb.


So for right now just the MOTU and External AD/DA converters.


Basic setup: Open Logic's Preferences/Audio, Default is the Devices tab Make sure your I/O is good. Set your I/O buffer to 128 or 64. (64 is better for your needs), in the same Preferences go to the General tab stop. Enable Software monitoring. You will be monitoring through Logic's audio engine. If you have any hardware monitoring from the MOTU disable it. When monitoring through Logic's audio engine, the lower I/O buffer reduces latency, you may be able to use 32 but leave it at 64 for now.


Basic recording will consist of either a single stereo track, or two mono tracks panned hard left and right.


The standard stereo track looks like this: Input 1-2 (notice the overlapped circles to the left, that's the stereo indicator, panning is dead center.


Mono channel strip: Input 1 (would be 2 on a second mono strip) a songle circle representing mono, -64 represents panned hard left, second strip would be panned hard right. The advantage of mono strips is separate eq and fx on each strip.


Good so far?

Hi Pancenter,

thank you so much for chiming in. This is my first encounter with a DAW! As a classical and acoustic guitarist and composer recording my own projects, I used to record on a dedicated hard disk recorder (Fostex D2424) due to its tape recorder-like interface and approach (always using external converters). I have however mixed and mastered my musical projects in a commercial studio which used Pro Tools, so I do know what a computer has to offer to those who make music:)


Having to start a new project after a long hiatus, I have recently bought a Mac from a friend (I am a Windows user for non musical things) and have installedLogic Pro X. As an old fart, as I mentioned, all this is new to me, and I am finding the learning curve rather steep- fortunately I am at ease with audio part of the job, analog and digital recording chain.

I bought the MOTU 8D because I will never handle more than 4 tracks for simultaneous recording, and I understood that its digital patching capabilities would allow me to patch and route effectively my Quantec and TC reverbs, and possibly other effects through an D/A/D loop, when mixing or monitoring.


Since you asked: Mac Book Pro (Retina, 2012) (2.6 GHz Intel Core i7). Mac OS Catalina ver. 10.15.2. Logic Pro X ver. 10.4.8


Do you also use MOTU 8D with Logic Pro X?

I have done some homework, so once I connect the Mac with the MOTU, the two see each other. I can open an empty project. I can record from my recording chain from my Acousence converter, though I seem to get one stereo track instead of two separate tracks (I record my guitar with two mics). I have seen a tutorial showing how to open an I/O plug-in in a channel of Logic and I am able to patch the Quantec with the other AES/EBU connections of the 8D, so I have another fader for the reverb return. But the results are erratic: I tried all routing combination on the MOTU (its Discovery application) but it seems to me that when the reverb is engaged (I can see on the leds of the MOTU the inputs and outputs of the dry signal and of the reverb send/return) the output becomes perfectly mono! Also, if on that same stereo guitar channel I want to open another I/O plug-in for another digital processor, the MOTU sees it (I now have three channel pairs active) but I do not have a separate fader for the return of the processed signal: I either monitor the Quantec, with the return adjustable via the fader, or I strangely hear only the TC Electronic all the way up, no fader. It is not quite as when I work in rehearsal mode in my studio where I have four aux ins in my analog mixer and I can mix and match different effects to my liking.

I do not want to necessarily print the reverbs. Having the luxury of many tracks for mixing, I wanted the stereo returns of my processors on different channels/tracks for monitoring and eventually mixing (with my rehearsal setup and analog mixer I am fine with the aux send pots in individual channels).


Sorry, too many words, plus perhaps a language barrier. Ideally I would need a step by step tutorial on how to make use of my external processors in my very simple recording/monitoring setup.

I do not know how not to monitor through the MOTU, as I mentioned.

I have opened one of you projects. I ca, hear the two mics and noticed the bus pot which serves as the amount of send to that internal reverb of Logic. Since you had mentioned the thing was now able to be set to be patched with my external fx, I opened the I/O window to be set to stereo input and output (as per a tutorial video I watched) on channel pairs 3-4 (same for ins and outs), then also 5-6, whatever. No sign of life in my fx box. Again, I am listening through headphones from the MOTu because I do not know how else to do. I believe I am really useless with these things, or too old:)

Here's a demo project with different recording options, did this quick, hope it gives you some ideas


https://www.dropbox.com/s/8batlbc0l9ykfff/StereoMonoProject.zip?dl=0


Track 1 is a stereo track using a Space Designer on a bus/aux.

Track 2 & 3 are mono tracks panned hard left and right, each track has two buses going to space designer reverbs w/different verbs.


Track 4 and 5 are mono tacks setup to use the I/O plugin. These should be able to be routed to your hardware.

It's a start.
