Me too. When they have an Android version I’ll definitely sign up for a trial. My current Qobuz Connect/AirLens setup sounds awesome. Can’t wait to see how Maestro might improve that.
I have a lifetime subscription to Roon, and now use it for…. My Denon speakers for background listening in another room, infrequently.
Maestro has such a beautiful sound quality. Yes, I’m hearing things I hadn’t heard before, with a natural presentation - and, it’s working through my BACCH4Mac. Another late night last night from sitting in the sweet spot!
I paid the annual subscription and happy to work through the glitches. Streaming playlists often stop - I get an alert that Qobuz may not play a certain track in my region (Australia), then it doesn’t move on. I’m controlling my Mac Mini that runs Maestro & BACCH via Screen sharing from my laptop which isn’t as user friendly.
Looking forward to the iOS release!
A note of caution for any Maestro users on Macs (Apple Silicon more specifically). I have a Mini M4Pro and upgraded to MacOS 27 which didn’t go over very well with 322 (or 321) for playback. I’ve sent logs to Paul. Advise caution on upgrading at this point although everything else on that Mac has otherwise been working just fine to this point.
I am using a Silicon Mac and upgraded to OS 27. Yesterday I couldn’t connect to my DAC. I deleted Maestro and re installed it. Still couldn’t connect to the DAC. However, I connected to the Mac speaker, then changed back to the DAC and it worked. Not sure why, but it is now playing local albums, radio and Qobuz. I still have several local albums that are coming up as duplicates but that is a relatively minor issue. I’m still loving the sound Maestro puts out on my system.
Yes with my Mac Studio 2 ultra the last couple of version nothing plays back except the test tones. My trial ends in 4 days so not sure what to do.
My story/experience with PMG’s Maestro. (I am from Denmark. Sorry about the spelling)
I’ve been a Hi-Fi enthusiast for 43 years - or perhaps even longer, though I probably didn’t realize it at the time, given how young I was. 
I’ve been on the Hi-Fi journey! Starting out by scraping together whatever used, old-school, or free gear I could find, and using it to get the best sound possible in my childhood bedroom to where I am today, with a highly revealing Hi-Fi system that I could only have dreamed of back then. (And the journey is far from over).
Only twice, during this long journey have I had that truly special experience where I said to myself, “WHAT ON EARTH JUST HAPPENED THERE?” - an experience I will now try to describe/share.
I think it’s perfectly normal to have equipment that matches what you have the time and money for, at any given time.
Experience first time! --I had reached a point with my equipment where I thought it would be hard to do any better - at least not with the amount of money I had decided to spend at the time. (Floor-standing speaker, Tidal, Streamer/DAC, Turntable, Preamplifier, Dual-mono power amplifier) - Then I got the chance to get my hands on a pair of Retro Mono power amplifiers from around 1983, for the same amount I could sell my old dual-mono power amplifier for, and then “WHAT ON EARTH JUST HAPPENED THERE” ??? I wasn’t even sitting in my listening chair, I was just standing in my living room, having just fired up these monoblocks and the sound!! and had a huge smile on my face, and my head just nodding rhythmically to the music. I never would have thought there could be such a huge difference between power amplifiers - in terms of the bass and the control over the music. YES! Now my system is playing MUSIC for the first time. I still have the two monoblocks, even though I don’t use them today and they sit on my bookshelf as decoration and remind me about the positive experience. I still carry that experience deep, deep within me, even though it has been more than eight years. 
Experience second time! – Throughout the next eight years I spent building up my system to the highly revealing setup I have today, chasing the next “WHAT ON EARTH JUST HAPPENED THERE?” - AT NO POINT did I come anywhere close to that first experience. You could certainly argue that it ought to be there, considering what the system has been replaced with over the past eight years! List of replaced equipment: Qobuz via ROON, All AC-power is from the PerfectWave P12, From routes- wired Streamer-AirLens, i2s-connected Stellar Gold DAC from AirLens, XLR connected Stellar Gold Preamplifier from the Gold DAC, XLR connected monoblocks- Stellar M1200 from Gold Preamplifier, Amplified signal to the speakers- Dynaudio X44 (these were also used during the first experience).
It has actually been very frustrating that “WHAT ON EARTH JUST HAPPENED THERE?” hasn’t happened over these eight years. It just couldn’t be right that you can’t get the same experience again!!
I was so frustrated and disappointed with the equipment mentioned above and how it has performed! There were very audible differences in the sound from day to day, and yes, it was utterly boring to listen to and in no way engaging.
I’ve been around the system the whole time to get it to play music. Cables, tubes in the M1200 - you name it, I’ve tried it! - without any improvement, whatsoever!!! YES, PMG (PS Audio) I was frustrated and accused your equipment of being unable to play music. You have always described the importance of your equipment playing music in such a way that you actually forget about the gear and simply lean back and enjoy the music. Sorry, BUT what else could be wrong besides, your equipment?
It was all very frustrating, because I had worked hard to achieve a lively and immediate musical sound in my living room, and that takes a long time for most people, after all. (for most people, after all, you’re somewhat stuck with what you’ve got - you can’t just keep buying new things all the time).
Since I’m still on my HiFi journey and constantly thinking about improvements, then PMG announced that he was developing/working on the music management program Maestro, and this program is said to be a clearly audible improvement over existing music management program, such as ROON. (I only wrote ROON! because that was the one I used)
Since I’m constantly on a journey of improvements, I naturally had to take a look at Maestro - or at least give it a chance. With the free trial and the fact that I already had Qobuz, it was easy to put it to the test!
After completing the Maestro-installation on my PC. (ROON is also installed here) Now I was ready to give Maestro a try! (Just want to mention that my setup hasn’t changed and is as described above)
I found the playlist I listened to the most before switching to Maestro and hit play! “WHAT ON EARTH JUST HAPPENED THERE?” “WHAT ON EARTH JUST HAPPENED THERE?” “WHAT ON EARTH JUST HAPPENED THERE?”
APOLOGIES TO PMG (PS Audio) for blaming your Hi-Fi products for inconsistent music reproduction from day to day, and for being boring to listen to and in no way engaging. I APOLOGIZE!!
Back to “WHAT ON EARTH JUST HAPPENED THERE?” Then it appeared for the second time on my journey. I can now confidently state that it wasn’t the PS Audio equipment. Now with Maestro, the system delivers rock-solid sonically stable performance hour after hour, day after day…… You could also describe it by saying that everything, and yes, I mean everything - has simply fallen into place as if by magic, and I’m 100% back to just listening to the music and everything it holds.
I used to be forced to listen to my equipment. I’m past that stage now. I’m happy, and it’s just so awesome.
Can now write, that it is very thought-provoking what “software” can do - both negatively and positively - to an audio file from the same provider, such as Qobuz!! Thanks, PMG, for your mindset regarding audio. Maestro works so well for me that I only want to use this one—even though the PC platform performs very, very poorly; yes truly, very, very poorly!! I am so firmly sold on Maestro - based on the sound quality - that I am forced to turn a blind eye to how the Maestro interface performs.
PMG, I know you are working hard to fix the poor interface. I’m really looking forward to an interface for Apple and Android! I know you say Apple is the one causing the delay, so perhaps you could look into Android instead? I would appreciate that. All in the hope that the interface will work better here!!
Best regards and MUSIC/SOUND to all you great Hi-Fi enthusiasts

Apparently, apple has broken things (again).
This is from the roon forum
macOS 27: Roon Server can no longer see your network audio devices
If your Roon Server runs on a Mac and your endpoints disappeared after updating to macOS 27, please read below to find out what to do while our team addresses the issue.
What is happening
macOS 27 blocks Roon Server from making outgoing connections to other devices on your network. The block happens inside the system’s network stack, before anything leaves the Mac, so Roon reports it as “No route to host”.
Incoming connections are not affected. That is why Roon itself still runs and your remotes still connect, while your speakers and streamers vanish.
Toggling the Local Network permissions or reinstalling Roon will not clear this, as they will not reset the state on macOS at all (confirmed by Apple).
Step 1: find your network address
Open Terminal. You will find it in Applications > Utilities, or press Command and Space and type Terminal.
Paste this and press Return. It only reads, it changes nothing:
ifconfig | grep "inet " | grep -v 127.0.0.1
You will see one or more lines like this:
inet 192.168.1.42 netmask 0xffffff00 broadcast 192.168.1.255
Take the address after inet, replace the last number with 0, and add /24. So 192.168.1.42 becomes 192.168.1.0/24. If yours reads 10.0.0.37, it becomes 10.0.0.0/24.
If your line shows a netmask other than 0xffffff00, please post the output in a reply and we will give you the right value. That is uncommon on a home network.
Step 2: apply it
Paste both blocks below into Terminal, one at a time, pressing Return after each. Replace 192.168.1.0/24 with your own value from step 1, and leave 224.0.0.0/4 exactly as it is. Terminal will ask for your Mac password. Nothing appears as you type it, which is normal.
sudo defaults write com.apple.network.local-network AllowedEthernetLocalNetworkAddresses -array "192.168.1.0/24" "224.0.0.0/4"
sudo defaults write com.apple.network.local-network AllowedWiFiLocalNetworkAddresses -array "192.168.1.0/24" "224.0.0.0/4"
Run both even if you only use Wi-Fi, or only Ethernet. They are separate settings and the unused one does no harm.
The 224.0.0.0/4 entry is not optional if you use Roon ARC. macOS treats multicast as local network traffic whatever else you exempt, and without it ARC cannot set up its connection.
Step 3: restart the Mac
Nothing changes until you do. After the restart, open Roon and go to Settings > Audio. Your devices should be listed again.
To check it applied
defaults read com.apple.network.local-network
No password needed, changes nothing. You should see both lists with your network and 224.0.0.0/4 in them.
Trade offs and undoing
It is worth knowing that this process tells macOS to stop treating your network as a local network for every app on that Mac, not just Roon. This is the mechanism Apple provided for exactly this situation, but it is broader than Roon.
To remove it later:
sudo defaults delete com.apple.network.local-network AllowedEthernetLocalNetworkAddresses
sudo defaults delete com.apple.network.local-network AllowedWiFiLocalNetworkAddresses
Then restart the Mac again.
Thanks for posting this. I went through it carefully, because if it applied to Maestro it would be a big deal. It doesn’t, and here’s why.
Roon Server is a background server program. The new macOS is quietly refusing to let that kind of program reach other devices on your network, and it never asks your permission first. Maestro is built differently. The Maestro app itself talks to your streamers and network players, and macOS treats it like any other app. The first time you open it after upgrading, the Mac asks whether Maestro may find devices on your local network. Say yes and you’re done.
I’ve now read logs from Maestro users who are already on macOS 27. Their streamers and network players are found and they play. You do not need the Terminal commands from the Roon post for Maestro. I’d leave them alone unless you need them for Roon, because they loosen that privacy guard for every app on the Mac.
If your players went missing after the upgrade, the likely cause is a wrong click on that permission question. On the Mac, open System Settings, go to Privacy & Security, then Local Network, and make sure Maestro is switched on. Then quit Maestro and open it again.
Golden Gate did break one thing for us, and it’s a different thing. Bit-perfect playback to a USB DAC can hang on macOS 27. The Mac never answers when Maestro asks to take the DAC over, so you get silence. Dang. That one is on the bench now. The workaround until it’s fixed is to pick your DAC as the output in the Mac’s Sound settings, then choose System Audio as your zone in Maestro. It isn’t bit-perfect, but it plays.
So if you run a USB DAC in bit-perfect mode, that’s the one reason to hold off on the upgrade for now. Everyone else should be fine, and today’s 11.0.323 is a good one to have either way.
Allan,
What a note. Forty-three years at this and only two of those moments. I know the one you mean. You aren’t even in the chair yet, and your head starts nodding before you’ve decided anything. Thank you for taking the time to write it all down. Your English is just fine.
No apology needed, not to me and not to the gear. Your AirLens, the Stellar Golds and the M1200s were telling you the truth about what they were being fed. That’s the whole reason Maestro exists. The player upstream matters far more than anyone expects. When it gets out of the way, the system you spent eight years building finally gets to show you what it can do.
You’re right about the Windows side. The sound came first and the interface is still catching up. Today’s update, 11.0.323, carries a handful of Windows fixes. One is the false network error that kept stopping playback. Another is settings that used to vanish after every update. It won’t let you stop turning that blind eye just yet, but it’s a step, and there are more on the bench.
The iPad app is in development now. I’m aiming for roughly the next couple of months, though I won’t put a firm date on it. The good news is that Android is a piece of cake after IOS is finished and they don’t put you through the wringer like Apple so expect an Android version soon after.
Now go put that playlist back on.
Welcome, Allan
Hi @Paul - Presume the iPad app will also work on iPhones?
Well done on everything Maestro - it sounds superb!!!
Welcome Allan,
I thoroughly enjoyed your 43 history. I appreciated your noting Apple as I cannot decide whether to update to iOS27 as I am currently on iOS26. I will wait awhile.
Yes, of course!
Hi Poul,
Thank you, and Thank you for Maestro, PS Audio equipment. 
Everything is rock solid and I can now enjoy music in a way I have never experienced before. I am back where I hear a song completely finished every time. (There is definitely something in the music I have not experienced before! and of course I have to include that) I got and have goosebumps over this and they just won’t go away again
BR. Allan J.
MacOS 27, Maestro 323
- clicking Stop at bottom does not stop music, stops timeline advance
- while playing a track, clicking the timeline stops music but will not play when clicking play button on bottom. to get sound, must click a track
- closing Maestro during a track play does not stop music playing through system until after about 12 seconds
Thanks and glad it’s working! We’ll keep improving it on a daily basis, some behind the scenes, others through updates.
@aspire, thanks for the clear description. Both of those point to the same thing: the controls on screen are changing but the command isn’t reaching the player. Another user reported something similar this morning, so it’s on the bench today.
Two questions. Which output are you playing to? That’s the zone name at the bottom of the window. And could you send me a log right after it happens?
- In Maestro, click Settings in the left sidebar under Tools.
- Click Export Logs.
- A file lands on your Desktop. Email it to support@maestroaudio.net and mention “aspire” so I can match it up.
wait til you try Bacch4Mac…
Baby steps!
Not a universal issue I think. I have Maestro and Roon installed on my Mac and Roon is working normally - streamers and speakers all there and playable. Not to say that a deeper fix from them isn’t necessary and sometimes the case with a major OS update.
