How do you use OTB effects in Logic? Digital Converters

How do you use OTB effects in Logic?

By using them in same way as you use traditional aux sends and returns.

Just wondering how you all do this?

Yep.

Create an aux buss, set its output to the physical output of my interface > unit > input x > track in Logic.

Or for 100% in-line, set the track in question output to the physical output of my interface to the effect unit in question > effect output to input > new track.

Sounds complicated in writing but it's not.

Plus if you want to get posh, you can compress or eq going in or out.

depends on your setup. i run the outs of my interface into the channel ins of the console and run my hardware fx though the auxes on the console. if you dont have a desk, you can use the channel in/out of your interface to connect to the sends and returns of your hardware fx and run it that way. there are lots of ways to approach it. find the one that works best for you.

if you want to mix it in sync/live with the rest of your song, use the I/O plugin. It reports PDC latency to Logic.

it effectively doubles your latency though. i go straight to summing with my outboard FX for this reason (i.e. no I/O plugin).

you don't necessarily HAVE to report the latency on reverb

you do if you use it as a hardware insert.

DAC > Reverb > ADC - an extra roundtrip+

This is true however reverbs and whatnot (for me at least) or not so critical if there're a few ms off, especially on high sample rates like 96k. Hardware compressors probably would need a nudge to be put back in 'correct' time honestly I never bother, not that I use hardware compressors on individual tracks anyway. Only thing I compress is the entire 2 buss mix on a Fatso. So in that case the latency DA > AD is irrelevant.

yea if you run at 96K on 64 buffer you should be fine. 256 plus you will notice for sure.

I wasn't talking about the device processing latency.

I was talking about audio interface latency and Logic's I/O buffers.

Not everyone can achieve blisteringly low system latency.

I guess most people here use desks / consoles then. I'm looking at something more rack based, either a mixer or an interface to start with.

Not really, my system is nothing special, a 2013 i7 iMac with an RME UCX. I can easily get 96k 24bit 32 samples. Possibly even go to 192k but honestly it's in the order of a few ms delay now. Prior I had a Mac Pro 2008 with a Apogee Rosetta 800, couldn't get less than 96k/24 256 samples with that set up.

I don't use a desk at all, everything goes in and out of my interface/Logic like a big tape recorder / mixer. Though I do dump my mixes to a potrastudio 4-track. and continue mixing OTB off there.

Not something I can achieve on my (high track count) system. I'd need a new computer, and expect that would have to be a PC.

I've dealt with enough people's latency problems on forums to know many aren't running under 5ms roundtrip.

Well it's time for a new machine then, though yes I almost always have less than 10 audio tracks. Honestly I don't understand high track count thing but probably that's just my straight forward tunes. Of that it's mostly MIDI and hardware, very little software I use other than basic eq, compression, delays and EXS24.

Sorry, I meant high channel count - for summing, synths and outboard FX routing. Summing alone eats up outputs.

I find having too many tracks on the arrange confusing - makes my eyes hurt. No more than 10-20 tracks.

I'm running a Digiface with different converters over ADAT. Unfortunately, one of my converters has ADAT-only latency of ~3.7ms (bloody Prism!), and I have to add Logic's I/O buffer (x2) and the Digiface's buffering on top of that.

Also, many people are using audio interface's that just can't reliably achieve under 5ms latency - my Orpheus doubles it's buffers when I switch to 96k for instance, so 96k only halves the latency of Logic's I/O buffers.

Here is how I do it using a MOTU 24i/o interface.



1. On your channel send, select the buss number you want to use and the amount of signal.
2. On that buss, select the output to the device you are using. In my case you can see where they are going because MOTU allows you to write the name of the device.
3. Create an aux return.
4. Select the output of that device on the aux return.
5. Have fun.

I might get a Focusrite interface, any known latency with them on older macs?
