Ok, I had assigned to output 3-4 inside of Logic on my last project and forgot to re-set it to 1-2. Please delete this thread, as I can't seem to be able to. Thank you! 😊

Hi all, I'm at a complete loss. My M4 works fine system-wide and with other audio software like Izotope. If I create a new project with LPX 10.7.4, assign the output and input to the M4, I can see the meters moving when speaking into the mic and see the output meters move when I activate the monitoring. I can also record my audio. BUT If I listen to the recorded audio through the headphones or speakers, nothing comes out of the M4. If I open any older LPX project, the meters move on the M4, but no audio comes out of them. If I listen to any other track with any other sw, the audio works fine, but albeit all meters moving in the M4, no audio comes out of it. I tried restarting both Mac and M4, no other sw is running in the background. (edit. I tried creating a new user and testing it there, and it works fine. So it's something related to this particular user.) I suspect it being something banal I'm overseeing, but for the love of me, I'm stuck! Any help would be appreciated. Thanks, Ian

Gotcha, yeah, in zooming in I can actually see that the virtual instruments don't match the actual music from that project, so it must just be some weird mismatch. Thanks for this, David.

Hey David, this project is in a folder in my Mac where I keep old projects. Was never moved. It dates back to 2014. If i select it in Finder, press space bar, I get the first preview... if in the preview window I press "Open With Logic Pro" in the top right corner, I get the second project. Doing this makes it so that the preview now reflects the 4-audio-track project. So now there's no trace of the version with virtual instruments which was what I wanted to work on. Thanks.

Hey all, I'd like to edit one of my old projects, but something odd is happening: if I preview the project in the finder pressing the space bar, I see a number of tracks with virtual instruments. When I open the project, there are only 4 audio tracks. There are no project alternatives, hidden tracks or other screensets. Any ideas on where the actual instrument tracks might be? Thanks, Ian

Oh, wow, didn't expect that! Thanks anyway!

Hi all, is there a function which starts recording when I press one or more keys on my M-Audio USB musical keyboard? I remember being able to do this 20 years ago on Digital Performer so I'm sure it's in LPX as well, but I can't find the setting nor a hit on Google, as I'm sure it has a specific name which I cannot recall. Thanks, Ian

There isn't much scientific research on this topic, but the little there is, looks encouraging: https://associationofanaesthetists-publications.onlinelibrary.wiley.com/doi/full/10.1111/j.1365-2044.2005.04287.x Yup, that's it!

Hey Christian, David, Thanks for that, yeah, I was reading up on the topic and found statements such as "Binaural beats in the delta (1 to 4 Hz) range have been associated with deep sleep and relaxation" to be pretty confusing, and now I realize it's 1 to 4 Hz range, not frequency. Thanks for helping me understand that. Regarding the Test Oscillator, thanks for that too. I guess I should output the track with the oscillator to, say, Bus 1, then create a new audio track that has Bus 1 as input in order to be able to record it.

Hi all, I'd like to do some tests with Binaural Beats and am looking for a way to produce sine waves at varying hertz. So, for example, I'd like to be able to create a 1 Hz sine wave and a 4Hz sine wave to then pan them hard R and L. Reading some old posts, I saw David suggesting loading EXS24 (which I don't see anymore in LPX) without any instrument and that should produce a pure sine wave. So my questions are: 1. What can I use to generate a pure sine wave in today's version of LPX? 2. How can I precisely set the Hz of this sine wave without having to work with pitch shift and cents? Thanks! Z

It does! Thanks to you too for the minor help, I guess, David.

Brilliant, Alan, thanks so much for all the precious time and info.

Ok that's the whole point of a crossfade though, so the behavior you're getting is expected. The crossfade means you're starting to lower the level of the audio file referred to by the first region and starting to raise the level of the audio file referred to by the second region at the beginning of the crossfade. In the middle of a symmetrical crossfade, the level of the two audio files are the same. Until the end of the crossfade where you've finished lowering the level of the first audio file to zero while the second audio file has reached its normal level. Example. In the screenshot below, the first Cross fade track is the equivalent of the two Automation tracks below: cross-fade.png Yeah, it does make sense. Yet I was convinced that it didn't happen before. I do a lot of podcast post-production and sometimes words don't sound right, say, in the last letter. So what I do is cut at the end of the word, drag the right edge of the audio file so that it stops before the last letter, cut that same letter from another word and paste it there. Then, since there is probably a click where one ends and the other begins, I used to do a crossfade in order to eliminate the click. Now I'm hearing both the prior and the new letter. I guess my questions are: Has it always been like that and it just happened to work for me every time hearing a bit of the original letter? Is there any way for the crossfade to work with silence rather than the eliminated audio? Is there a better way to make it work? Think I might be going a bit nuts during this quarantine!

:facepalm: Sorry about that...

Hey Alan, thank you for taking the time. My problem is this: if I drag an audio over another either with Overlap or with No Overlap, what happens is that if I do a crossfade to make the meeting point sound seamless, the wider the crossfade, the more of the audio that used to be there will be sounding. I don't get why placing a crossfade makes the audio I had previously cut out comes back out. Most of all, I don't understand how not to make this happen. The same thing happens if I just shorten both audio files, then drag them so that the end of one matches the end of the other one, then I add a crossfade and the audio that used to be there comes back out and overlaps with the other one. Hope I explained myself sufficiently well for you to understand my problem. Thanks!
