Control ST3 on ipad from iphone
- Edited
howifeel I made a video that may address this.
THANK YOU FOR SHARING 
it, hereās my IPhone remote and it works perfectly, I just need to place volume up and down on it which will fit nicely because I can afford to reduce the icon sizes, this will basically give me 12 button control on iPhone, there is no such remote available I know that gives you that power.
Well done!
Thanks again 
Damir Nice looking surface! Yes, I use network, as well. 5g is cleaner and faster but not good for distance, 2.4 is good for distance but is a little slower and it is a busy WiFi frequency. I am so glad you got it going so quickly. I donāt understand why I got thumbs down on my vid other than I blow through it pretty fast or I use another app in addition to ST3. Nevertheless, it feels good to help! You seem very tech savvy.
howifeel above all, thank you for the video!
Now unfortunately I do not have the acces to see the iPad when I use the iPhone so this is not solving my issue. I'm looking rather mirroring the ST3 somehow.
Your idea is super nice, but I cannot see the playlist on my iPhone or scroll thru the songs, I mean I could with the next/previous but I have 100 songs in one list..
Do you have maybe any ideas on how can I see the list I have on my iPad, but looking on the phone?
Thx and again, congrats for the idea!

howifeel I would need to dig into that as I have no idea what an IEM is. But this week end I will try with bluetooth, to see how the latency is behaving...
Thx a lot for the input and ideas ideas

howifeel I have used IEM for many years, and every now and then I get disturbances, spikes of noise or white noise. I would never trust reversing the intended signal flow, going to my mix and PA. And no, they have not been cheap systems. Shure and Sennheiser.
howifeel hahaha, of course I know what in ear monitor is and how its working, but abbreviated was just not clinking in my mind. ahaha. super funny.
And funny enough, I was looking at exactly the same topic when opening this forum. I'm looking now at NUX b-7 psm, but honestly it would be nice to have more ideas. Is there any other option that is stereo and you know about it?
I would pay, it does not matter is is expensive, just to be sure that the signal is not dropping!
Lets see, maybe we find other ideas!
Cheers,

royandreno that is good to know... I had the same feeling somehow, I used a shure years ago, playing some gigs on big stage, never had issues with that, but somehow i don't trust it..
Thx

Tavilazar I came across a Sennheiser device for home use that runs on RF signal and is virtually zero latency (almost).

I have used this and it works well though I went with another systemā¦

Well, ive been thinking of the same.
Right now iām using my 11āā iPad Pro on the floor for lyrics, while the phone is my main source for stereo backing tracks via airplay. Not quite ideal.
If there only was an app extention for the phone that contained only the song list that would trigger the ipad remotly (like the ipad being the main unit with the phone being the Ā«control surfaceĀ» for Stage Traxx on the ipad).
That would fix everything for me!!
This solution would make a more solid playback solution possible from the wired iPad Pro as well as being my lyrics prompter. Controlled only by the phone barely visible for the audience
Version 4 will have remote control capabilities.
peter no disrespect, but how long do we still have to wait? I know itās a lot of work to implement all the stuff you want to do, and it takes time, but for those that need certain functionality now, I would encourage to keep looking for ways to get things accomplished, until that glorious day when ST4 is released. I am certainly looking forward to the day!
