Studiomux and Bluetooth question
I managed - after some trial and error and a bit of help from @aleyas to get Studiomux to send audio from Ableton to AUM. The audio sounded fine coming through the ipad speaker but when I routed the audio to my Bluetooth headphones it was badly distorted. What could cause this? Cheers
Comments
Distortion usually appears when CPU can’t handle the demand any longer. Increasing buffer might help.
I stopped using SM because of reliability issues, but from my memory, you are dealing with 3 separate buffers here added together. AUM, Live, SM... and you, need to find a usable balance between these buffers. Do you notice CPU spikes in AUM or Live before switching to BT?
@Gavinski Not very helpful I’m afraid, but I’m wondering why you want to monitor from the iPad when you’ve achieved the miracle of getting the iPad audio in and out of Ableton?
More helpful I hope is a link to my previous post about Studiomux / AB / AUM setup. I had a lot of success and stability with this setup, so you might find it useful? That was iOS 13 a few months ago. I’m about to go back in on iOS 14 and the new Studiomux beta, so bracing myself for some pain - that’s why I found myself reviewing my previous happy time

Thanks Steve, will take a look at this. About audio in and out, true that I could maybe send just send the ipad audio into ableton, haven't tried that yet, was enough hassle getting it from studiomux into the ipad lol. I'm just used to doing my screen recording and making the vids on my ipad. I want to start using some desktop apps but want to change my existing workflow as little as possible, as I am used to it already.
@Gavinski Of course - the videos, very good reason - could definitely have used some of them from you when I was trying to get my head around Studiomux. I'm currently migrating from desktop and/or iPad to laptop and/or iPad for a forthcoming recording session, really glad I'd posted those screen shots to remind me how I set it all up. Audiobus was definitely the rock it was built on, much more reliable with Studiomux than AUM on its own.
I just now had an unpleasant discovery about idam by the way. On my ipad Pro 3rd gen it will only work if I go directly from ipad USB C to laptop USB A. If I try to use a USB hub, I then need to go USB A to USB A, and this no longer works. This means, for example, that I can't connect my audio interface to the ipad at the same time as I connect to the laptop via idam. Why is this and is there a workaround?
Well, I noticed massive cpu spike in live while using idam to send midi to live and then trying to screen record on the laptop. Ughh, I hate this kind of shit, why so messy and complex....
There is a very new, totally different workaround if all you want is to record from the laptop with audio interface connected:

@rs2000 will look into it, thanks!
I believe that's inherent in the idam protocol. Both iPad and computer are configured as USB masters. They normally connect to USB slaves, keyboards, mice, audio interfaces, etc. For idam to work one of the devices (probably the iPad) has to act like a slave to the other. So, iPadOS fudges the USB-C interface to act like a USB slave. Once you bring other gear into the picture, the iPad behaves as a normal USB master, and the computer can't talk to it any more. This master/slave issue is why standard USB cables have different connectors on each end. A USB-A to USB-A cable would be a "cheater".
@uncledave ah, that makes sense i guess, still a hell of a pity, cheers though
Could you get around the IDAM issue by connecting the MacBook to the hub and the iPad directly to the MacBook?
I haven’t tried it, but know that both work separately.
A> @Gavinski said:
Perhaps in addition to the inherent latency of audio over bluetooth there is some jitter that causes problems. I’d avoid Bluetooth audio for anything where real-time performance matters.
@Gavinski At the risk of asking the same stupid question twice, why not use the audio interface on the laptop? Then send audio to the iPad from DAW using Studiomux? That’s what I do for mic and guitar. I’m still amazed with what can be done with Studiomux and IDAM, pretty phenomenal to be able to bring the two ecosystems together over a lightning (in my case) cable.
Alternatively, have you considered an iconnectaudio2+ or 4+ interface? I was stalking them on eBay until I discovered Studiomux.
SonoBus is very cool AND performance over WiFi can be somewhat variable due to the nature of WiFi (wired network connections aren’t recommended by the devs). It worked well for me with full-fidelity audio (at the cost of a fair amount of latency) when I was the only person on my network. Otherwise, there where occasional clicks and pops die to lost network packets (which are out of SonoBus’ control...networks can lose packets)
My WiFi isn't great so I'd be surprised if it works well, but I have downloaded it and will try it for sure, nice that it is free
I'm sure an ad-hoc WiFi connection will work better.
