Is there an option to make the Brainwaves only pitch shift notes below a certain range, preferably only the lowest note played, and leave the rest alone? I'd like to emulate the "Range" parameter from the Boss OC-3, while not having to use a Boss OC-3.

That would be very useful for doing walking bass lines alongside chord-melody.

Hi there! 

...still a noise leaking from mix knob (even turned full left) unless you put a free cable into ext audio....

That s not an acceptable solution, as we lose the use of noise....

Is there something to wait? Should we all return the unit in warranty, at our cost?

An answer, for once?

Thanks

Quick history. I used a 24 channel D&R Orion (discontinued) for recording into my adat HD24 for many years and could not have been happier with the sound and mixes I was getting from that combo. The D&R is a totally analog console, so I never had issues with latency. Well, life changed and I needed to part with my console because of the space it occupied in my control room; especially with the giant 5’ dual rack full of outboard gear and other stuff. I sold the D&R and all but a couple of pieces of gear, but I still wanted a way to record and mix. I ended up getting an x32 rack used, adding the X-adat expansion card, and keeping my adat HD24 because I like how it sounds, I know it so well, and I don’t have to set up and learn a DAW system. I love the features and seemingly endless flexibility of the X32, but I have been having difficulty achieving mixes as cohesive as with my former setup. It is difficult to describe precisely, but the overall sound of a mix is a substantial step down from what I was able to achieve before. My belief is that this should not be the case, and after a lot of thought I think it all has to do with console latency. So I did an experiment to gain a better understanding of the various inherent latency figures/issues of the X32. With regard to studio mixing, I have made a simple discovery that may help you if you are using a similar (adat/X32) rig.
Let’s get right into it.
Lesson 1: identical signals of opposite polarity yields 100% phase cancellation. I think most people know this, but for illustration, make a copy of a kick drum track. (I use a Lawson L47fet about 22” in front of the bass drum on level with and pointing straight at the center. It gets the bass drum fundamental as well as some pleasant ride cymbal underside tone). In the X32, place these tracks next to each other and pan them both center. Muting all other channels, flip the polarity of one of the tracks and notice the complete absence of signal. This, of course, is because these identical signals are now 180 degrees out of phase, or completely out of phase.
Lesson 2: extremely small changes in phase (timing) can and does induce significant changes in sound. Once again, I think a lot of people know this, but for illustration, use the “Track Slip” function on the adat (or however you do it in a DAW) to either delay or advance one of those identical tracks by 1/10 of a millisecond. Make a particularly strong mental note of the result. If you can’t hear the rather drastic change in the sound, you should have your hearing checked. Yes, in studio mixing you can indeed clearly hear phase discrepancies resulting from a phase/timing change as little as 1/10 of a millisecond. I’m sure live mixing (which I know very little about) is different relative to what can be perceived, but there’s no mistake in what I’ve described above.
Lesson 3: the ability to advance a track in the adat HD24 or a DAW can help overcome (to a large degree but *not completely*) effect induced latency. I think a lot of people do not know this, or they, like me, have struggled getting a handle on how to compensate for the latency issue. So here’s what I figured out using the principles in lessons 1 & 2 above. Return your track slip back to zero. Now apply “Wave Designer” in tyher X32 with all settings at zero to one of the tracks. Turn the effect on and let both tracks play back at the same level while toggling between effect on and effect off. Note the marked latency induced phase wonkiness whenever the effect is applied. Leave the effect applied to one track while continuing to monitor both tracks. Now reverse the polarity of the track that has the effect applied, then begin advancing that track using Track Slip (or your DAW method) *by increments of 1/10 of a millisecond* until the signal gets as low or weak as possible. Notice that each increment changes the sound very perceptibly, but notice in particular that the low frequency keeps dropping off as you advance the track. You will eventually reach an increment which results in not only the greatest loss of low frequency content but also the greatest loss of signal strength/volume. Mine was 1.4 ms. When I advance it further to 1.5 ms, the low frequencies and volume both begin to return. So, if you use that effect on a track, advance it in the adat by 1.4 ms. That’s the best you can do. Ideally, we would like for the signal to go completely away using that method, right? Well, it won’t because you would need an even finer adjustment of time as in 1/100 ms or even 1/1000 ms or beyond). This may be achievable in a DAW, but the adat has the 1/10 ms limit. Anyway, once you’ve got that signal as low as possible, then flip the polarity back off. Mute the dry track. The sound should be much better in context because it is more phase coherent. Not perfect, but better.
Hope this helps someone, and it would be nice to know if one of you DAW experts finds a more exact (maybe even THE exact) track advance figure.
A final word: I haven’t tried it yet, but I think one could use this same technique find out about any latency when you insert an analog device through the aux jacks.

Apologies if this has been covered before, i did search and couldn't find anything

Hope to use my XR 18 at an upcoming gig (to save space) but cannot find in the XAir app where the Library presets are.

I use these a lot on my X32 in X32 Edit

Am I missing something or are they not available with XAir/XR18 setup?

Thanks in advance, have a good evening (or morning) if Paul V is reading this

A simple one first; select any channel, Hit the home button, under the input section, it displays the current input.  if you touch the displayed icon itself  for that channel - nothing happens.  if you touch where is says "INPUT" or touch the little set of icons under the home button, it takes you to the CHANNEL INPUT / TRIM & BALANCE / FILTER section.  How about they make it so the displayed icon on the HOME page, brings you to the CHANNEL INPUT / TRIM & BALANCE / FILTER section?  

Here's a tougher one; It sure is great to label inputs on the patch/routing section.  Thanks to my lovely wife, for "letting me" keep the Wing setup on the dining room table all of this month!  Anyway, I find the routing is sometimes rather clunky to navigate around.  It seems that there needs to be some additiional ways that are more intuitive to assign sources to channels.  The toughest way to do it, is if you have this "old school" workflow:

- I have a blank channel on the console, so I'll name it RALPH, easy enough.

- I need to patch a source to RALPH's channel, so (see point above) - ugh...

- I get into the INPUT section, tap the icon under the MAIN side of MAIN/ALT,  pick the SOURCE GROUP dropdown if needed, tap an input, and ugh - I want it stereo and to name the source "RALPH" and I can't - so, now I have to go hit the ROUTING button, then push STEREO and then the TO SRC button to copy the channel name to the source input(s). - not as easy.

Thanks for listening!

Just a note that the RTA is always stuck on whatever channel is currently displayed on the console, in the Mixing Station app [ currently 1.03(12) ]

I submitted it David, he said it was a firmware limitation, and there was nothing he can do about it right now.

- This happens on both Android and IOS (Mixing Station) pro apps.

- I also checked out the RTA Autogain feature, and right now that only works on the console, and not Mixing Station.  The app has it's own seperate "RTA Offset" knob for the RTA.

btw; Mixing Station Pro works really great on the iPad! The custom layers & layouts load up across different platforms really well!  Hope you add copy/paste on the app sometime soon!  I find that with custom layers and layouts, your app is much easier to use than the console itself.  I attached a "16 channel" layer and layout file* for fun.  You can unzip the .msz file, copy it to your google drive, then load the file from google drive directly from the app.  I setup the custom layers in it to always keep the DCAs availible as much as possible for speed.

- ( * the mute buttons still need to be assigned in the layout.  

Nice Job David!

Thanks!
