How to have Cubasis input to tv? (Solved!)

LinearLineman

Probably simple but I figured I’d just ask and save some time. My eyesight has deteriorated to the point it has taken the fun out of it. Trying to see the numerals tries my patience. Kim hoping this will solve the problem. Thx!

You could use any hub with a HDMI connection to you tv. Apple sells a dongle for it too. You can add a wireless mouse and keyboard for more fun.

Lighting iPad or USB-C ?

Alternatively, if you want cable free you could get a Apple Tv and screen share with the tv. But that leaves black bar on each side of the tv since the iPad screen size is not as wide as tv 16:9 ratio. Most tv anyway.

If you have a 2018 pro or newer I would recommend option 1. Stage manager on the tv is pretty sweet

If the cable-free option you are mentioning is Airplay, it has pretty significant latency, I think.

You really need a mouse and keyboard too. It's no help if you have to continually look up at the screen, then squint down at the iPad to figure out where to put your finger, adjust something, then look back up at the TV to see what you just did, then find that your finger is no longer on the control, over and over and over.

Get the Apple version. There’s a Video Converter chip in the white plastic adapter that justifies the expense:

It also has a Lightning Power port so the iPad won’t shut down.

An alternative, is to use a wireless connection called “AirPlay” to an Apple TV and the Apple TV does the HDMI conversion. The main benefit might be Dolby Atmos 7.1 channel audio output if your target TV system has high end audio features that you can’t drive from the iPad. I’m not sure what it might do with 2 channel iPad music files other than spread them across the channels in some manner.

Airplay might be fine for watching movies or doing slide shows, but I find the time lag too big for anything kind music creation.

Yes thank you it's called Airplay.

Their is no significant latency on my network. I used to play game on my tv using Airplay and a wireless game controller in my old iPad 2017 Pro. I have not tried with my M2 pro.

But it is a good point. I don't do live jamming so latency is not a concern for me

I read on another Reddit site that the Apple TV has lower latency than the HDMI adapter because either way one of these options has to convert Airplay video to HDMI and the Apple TV has a more powerful processor to satisfy the gaming crowd. The HDMI adapter has a low power ARM chip embedded in it.

@TheAudioDabbler raised this question about latency on this thread:

https://forum.audiob.us/discussion/58009/lightning-to-hdmi-adaptor#latest

I think he settled on a Roku device Airplay support.

@wim, I’m afraid you’ve put your finger (so to speak) on the problem. But I dislike the thought of a mouse and computer. What I need is a 50” touch screen.

@McD @ecou i have Airplay on my Samsung tv but as has been said, the latency,

I have both Apple tv and the Apple dongle with HDMI out. I will test that out tomorrow morning.

You could get away with just a Bluetooth mouse, probably, unless you would do any typing keyboard input. All you need is something to keep you from having to adjust things on the iPad screen with your finger. The mouse would give you a visual indicator and save you having to look up and down all the time. I think you'd be surprised how intuitive using a wireless mouse would be.

Latency - that's a problem. I can't imagine playing as you do with that level of latency - unless there would be some way to monitor the iPad audio not through the TV.

LinearLineman

@McD, of course I have to buy an hdmi cable, too. Nothing particular, I assume.
@wim, I think a Bluetooth mouse might work. I would be using it for mixing down if that isn’t obvious.

Then audio latency probably isn't a big deal. 👍🏼

I just did a quick test with screen mirroring to AppleTV using Loopy, the latency was fine. His is different from AirPlay which does have latency. With the screen mirroring, there was no delay between pressing the play button and the audio playback starting.

For my latency test. How is your midi keyboard plugged to the iPad ? Bluetooth or wired ?

How would you listen to the sound ? iPad speaker, speakers or tv speaker ?

espiegel123

I was surprised because using airplay to stream audio from my iPad has. 2 second delay between the play button being pressed and the audio coming from the stereo.

LinearLineman

Thx @espiegel123. Screen mirroring!
@ecou, hard wired. I’ll listen on hardwired phones or jbl monitors.

It took me a little bit to remember how to do it. You use the circled icon in Control Center once you are in the app you want to mirror.

That's what I did when I played Genshin Impact. Latency was not noticeable. But I do have a gaming wifi router.

I’m Googling around seeking some latency specs for various options. So far, I have found this:

These adapters are just USB 2.0 display interfaces with a little bit of special sauce. The pricing is actually quite reasonable compared to other such devices on the market.

Menneisyys2 did a bunch of testing and posted some results over at the MacRumors thread on this topic.

1. Video mirroring happens at 60 fps, not 30 fps as it does when streaming via an Apple TV.

2. The lag is around 83 ms (5 frames), as opposed to 50 ms (3 frames) when compared to an iPad (3rd gen) using the 30-pin Digital AV Adapter, or 150 ms (9 frames) in a best case scenario streaming to an Apple TV (3rd gen).

3. Video out mode works without transcoding, at full quality 1080p and supports Apple’s closed captioning. Furthermore, 1080p60 decode is supported when using third party video apps (Apple’s Videos app only allows syncing of up to 1080p30 content).

Menneisyys2 is working on more tests of 1080p60 playback and to see how high bitrate (28-40 Mbit/s) content is handled.
The artifacts that occur when mirroring are a totally normal result of H.264 encoding, which is a very lossy process. This happens with any USB display adapter, and is one of the major reasons why a native display interface is preferable.
Apple’s choice of 1600×900 as the rendering target for mirroring mode makes a lot of sense when you think about the native resolutions of the devices which can use this adapter and the amount of scaling required:

iPhone 5 and iPod touch (5th gen): 1136×640 (16:9)
iPad mini: 1024×768 (4:3)
iPad (4th gen): 2048×1536 (4:3)

Also keep in mind that when you’re mirroring, auto-rotation is still supported. No matter how you slice it, you’re going to have to deal with letterboxing and scaling if you want to mirror these devices to a 1920×1080 display.

Yes. That cable will carry video and audio to the TV.

I’m trying to imagine your actual use case. Will you bring up Cubasis connected to your Kawaii keyboard? I think you use
a Camera Kit Adpater for that connection so will you want to do this another way like Bluetooth?

Latency becomes an issue typically when you press the keyboard and want to hear the sound from speakers and I guess in
this case those speakers are in your TV or connected to the TV.

So Mirroring over WiFi leaves that Lightning port open for the CCK adapter but you need an Apple TV (or I have heard a Roku works).

I expect the 83 ms will drive you crazy. Maybe the Wi-Fi mirroring would be better. The Wi-Fi goes from iPad to your Wi-Fi gateway to the Apple TV with HDMI encoding processing to the TV.

Another option is to use your current speaker set up and just mirror the video to the TV and NOT use ‘its speakers. The visual latency for music apps is less of a problem than video gaming.

Be careful here. When you mirror the iPad screen, the sound is also sent to the TV. Switching audio output back to iPad turns off Mirroring. Using an audio interface may preempt this. I believe that's also the case with the HDMI adapter.

He did say the use case was fir mixing.

Here’s my test report :

I first tried my tried screen mirroring and I did see a small latency with a wired mouse plugged thru the USB-C port. But that was totally usable especially for mixing. When i switched to my Bluetooth mouse that latency was significantly higher and on the annoying side.

Then I tried using Apple dongle thru HDMI and that was definitively the best option. The latency was not noticeable at all.

In your case I believe you have a Lightning iPad and I don’t know what the latency will me. Maybe you can buy the Apple lightning/hdmi dongle at a store that let you return it and give it a try if it works for you.

@ecou @wim @McD @espiegel123 and everyone else. Simple mirroring does the trick. No perceived latency for me. Wim, there’s no problem keeping my finger on the slider. That’s mostly where I need to see the readouts and see I do!

My UpLift desk is serving an additional purpose here so I can stand without craning my neck and, of course, I can do it, sitting, from across the room with headphones.

I had to mute the tv speaker as it was breaking up now and again. Now the sound is perfect.

So simple. On balance, Apple is my friend. Not to mention 21st century technology.

THANKS, EVERYONE!

(Lol, the Seaboard is still beyond me but I like to look at it! I’d consider selling it to someone on the forum for a good price. Let me know if you’re interested.)

Such a letdown. What possible worth is an Audiobus Forum assisted solution if it doesn't involve cobbled together apps, expensive hardware, chewing gum, and duct tape?? And solved within 30 posts, without a single insult or argument?

This place is going downhill.
