This is a possibility: if you click on a track header, by default it highlights the regions on it. If you accidentally (or on purpose for something else) press the delete key it deletes the regions. You could have done this by looking at a different part of the arrangement, scrolling around. David said this many times here: click on the empty background in the arrange area before highlighting regions to delete. (This deselects every region) Other ones might have been selected (out of view) and you delete all selected ones. I think there is a setting where you can specify to select or not select regions on the track when clicking on a track header. Most of these problems are unfortunately user error. It could be the case here too.

This helped a lot for troubleshooting. So it is not Logic. The solution lies within the interface OR your headphones. I don't know the interface(seen it on the internet) but is there a MUTE switch on there? Can you test your headphones on another device to rule out a problem with the headphones? Have you tried to restart your Mac? When everything connected, can you hear the audio from a YouTube video?

The brand name is : HELIX. I can't find the exact model on the net. It is 3 years old now. It has 4 USB A ports and 1 USB C port.

All of the M series Macs are insanely powerful. The problems people experience are almost always because of incompatible 3rd party plugins, bad drivers for interfaces, shady hubs, wrongly formatted SSD's connected, people trying to save projects to the cloud and other unrealistic crazy stuff. To troubleshoot: start up Logic without any plugins (google it) and disconnect all peripherals. Try connecting suff. See if it's ok. If all good, try to disable plugins. Try disabling first half then the second half of them. Narrow it down. Plenty of info on these here in the forum. Do a search. Good luck!

Well, now you know that you shouldn't have anything on your stereo out as a mastering chain if recording things live. I think your real question is, you would like to keep those effects on the stereo out so you can just turn them on or off after adding recordings and tracks etc. The way around that is to save that channel strip as a setting. Before recording or adding tracks you just press reset channel strip then after you're done with the recording you just load it back.

Worth a shot: Did you have latency inducing plugins in the original project on the stereo out? If you did: After making a copy of that project to the internal drive, try saving the channel strip setting on the stereo out (so you can recall it later) then on the stereo out: reset channel strip. Did this fix it?

I am not at my desk and can't remember the brand name of my usb C hub. Bit it is a $20 hub from Best Buy. I have my Focusrite 2i2 and my midi keyboard and an external ssd hooked up to it and charger. I am actually in love with the hub. Everything is plugged into it and when I walk up to my desk with my MacBook Air I place it down and I have to plug in only ONE thing and everything is connected. I can't imagine plugging in 4 things each and every time. It would even look more cluttered, having cables sticking out of the laptop all over every side.

M1 Air here with 512GB/16 GB Ram. It is the least powerful Apple Silicon Mac in the lineup but still more powerful than an Intel Mac Pro in many ways. (And people got pro level recordings done with the Mac Pro) I went for 'fanless' because i record at my desk with a mic a lot. There is no chance the fan would turn on 🙂

I do miss the magsafe charging 🙂

The wedge shaped iconic wrist saving design compensates for that a bit. 🙂

The first time in Logic's history, the M1 Air is holding up after many years of Logic updates. Still a beast for Logic. In the past, Logic would update and a few years old Mac could not keep up. Like: - When Alchemy was added. I played a chord with certain patches and the CPU maxed out. - Logic introduced Chroma Verb. At the time my Intel MBP was i think 4 years old and could not play that reverb visualization within the plugin. The M series chips are godsend for Logic users. I still edit 4K video in Davinci Resolve while composing music in Logic on my M1 Air. For hours. On battery. On the go. Is this a dream or what? 🙂

I think what you're trying to say is you're able to produce that delay sound by playing with the delay live. That means you haven't recorded the pedal movement as a performance? You need to record automation of those movements of the pedal maybe. Once you do that then you can bounce in place or bounce the entire project or you can do whatever you want as Jordi said. Do you actually hear that delay futuristic sound when you play back the project and do not touch anything? If you don't hear it then it won't be in the bounce.

Maybe your DELETE key on your keyboard is sticky? You select a note with the pointer and that's why it gets deleted? Try to open the notes app and write something. Is the text getting deleted randomly?

If you have another plugin before the adaptive limiter and the sound comes OUT of that plugin too hot(distorted) then all that scale knob did, is turning down/up the distorted/too hot signal. Not useful. One has to make sure to get a healthy signal going in and out of each and every plugin in a chain of effects on any channel strip.

Short answer: no (i think) Start over. Save project as folder and include all assets in folder when saving. Make a copy of your project/folder. (To not accidentally mess with your project) Open the new duplicated project. Disable all plugins on stereo out. Do a better mixing job of your project. Get busy with your high pass filters on individual channels. Take care of all loud audio/spikes in your mix. If you have a decent mix, the mastering process should not alter it too much. Just make it louder, compress it a bit, even out the mix and tonal adjustments. Maybe all you need is to play with compressor on the stereo out. It helps if you bounce the mix to a stereo file (without any mastering) and import it into a new empty Logic project. This way you can see the waveform. If it has too many large spikes in the waveform, that is why the compressor/limiter is struggling in your master chain.
