Mainstage 3.5.1 recordings being in mono

I also checked on my 21" iMac from 2013, but it does also record in mono. When I pan my piano to the left, it does not record the piano at all . When I pan to the right, it is there. So there does seem to be some structural issue across my two apple devices.

The 21" iMac does not have the issues with glitches.

Guys, whilst Apple engineers MAY see posts on this board, you really need to submit feedback about bugs directly to Apple via the “Provide MainStage Feedback” option in the MainStage menu.

Ok , thanks for the gentlemen like response! Not everbody on the internets has the decency for a meaningful answer .

My ears are not good enough to decide it's mono in my case, but it definitely lost some clarity, so maybe it is mono. I find it hard to tell just looking at the audio signal . Only thing I noticed in my issue is that my output signal is very low, some 10% of the max, when I look at the signal in garageband. It's maybe one of the causes, if the signal is so low, you loose resolution. Still, my volume sliders are not way down, and in my headphone sound level is very high, so I'm wondering if this is really some hardware issue, or wether I just should crank up my outputs. Maybe something changed in recording levels between the current and previous MainStage version. I will try tomorrow to record with a higher output.

I attached an image below of my problem. You see also on the left channel the signal sometimes is zero for say 0.1sec. This somethimes happens on the left channel and sometimes on the right channel and once I saw it on both channels. I'm afraid I have a hardware issue.

How do you see it is mono? Is it really a channel missing in the recording?

after the big sur update with MainStage 3.5.1. my recordings sound really weird. As if my headphone is not wel plugged in , or low res. It does have two channels though in the recording. When I play back, sound is terrific, as usual. CPU load is below 20% or so, not a glitch whatsoever. However the recording sounds really bad and it has glitches: for like 0.1second the left channel has all 'zeros' , a flatline, and then the signal continues. Occasionally it is on both channels. It will do this every 3 or 4 seconds. All in all, my MainStage rig became unusable for recording a song in my homestudio. Live playing will still work.

I use a Focusrite 4i2 audio interface, but the problem also occurs when I disconnect it and use the internal sound only. It gives the same result. It sounds great through the headphone while playing, but the recording sounds muffled and it has glitches.

I am really stuck on this. One of my favourite pastimes is not possible in this way

Did you fall this as solved? If this flag prevents apple to look into this post, please remove that flag!. Downgrading is not a solution really, you loose security patches and other new functions. I can not work with lower versions.

Also I read somewhere Apple disabled downgrades with big sur, but probably you can work around it somehow.

After you mentioning it, I am considering downgrading, just to try if it solves anything. With the help of time machine I should be able to revert back. It will take hours though to do, and I don't really have time for this.

My 21" iMac from 2013 has no issues with MainStage and big sur, so I'm guessing it's a hardware specific issue.

Guess what, I tried panning and when I turn it to the right channel, my piano sound dissapears, only to come back when I turn panning towards left channel. So , I guess, I'm also having a mono signal!

I noticed also that despite my level output meters being at some 75% , the digital signal does not go above some 15% of the max value, when I look in garagaband to the waveform. I think probably it's related.

So, now what?

What mac device you use ? Also a 2013 macbook pro?

Im using a brand new 13 inch M1 macbook pro.

Given I started on this version it isnt feasible of me to downgrade.

Had to resort to sending my outputs to my windows computer to record :(

Apple please fix ASAP!!!!

Thanks for the pointer where to find this feedback option. I was looking for that , but couldn't find it. I will submit feedback. Thanks for sharing you have the issue with a new M1 chip macbook, it really doesn't seem to be a (failing) hardware issue - and I hope if new MacBooks also suffer, it wil be a bit higher priority fro apple than me on my trusty 2013 macbook pro.

i cant find the recording work flow in the help files. dyslexia maybe, all i can see is the part where it says you can press the record button.. where does it record to and is there any configurations? i press record and assume it should end up in the project folder but cant find it, also shows no indication its recording...

If you go to MainStage -> Preferences -> Audio, then in the menu there is a Recording section. That it where it shows where the file goes to. There you can change it. The saved file has the name of your concert plus a timestamp and ends on .caf as an extension

Indeed there is no indication on screen that it is recording, other then the round symbol on the record button turning red.

I think the default location is in your music folder, and then subdirectory MainStage. Same folder where on default iTunes files are stored, and Garagebands default saving directory.

Mine doesnt record at all now :S

Same here.. using a Shure MV88+ USB mic that has a stereo out. Both outputs are selected in the audio settings, but left channel is completely missing. Extremely frustrating.
