So its all good.

I think, latency is great on my iPad and iPhone - as long as there is no second app accessing the audio output as well. Maybe there is an internal mixer involved which is bypassed otherwise ?
I‘ve tried to play along to a song from Apple Music when I noticed a bigger latency than before. My score reader Newzik sometimes has an influence, and sometimes not. Maybe because of its metronome (even when off)?

Sorry for the late commnet as I am catching up on this forum. Did you find a solution? There seems to be something really odd in the transmission chain. Like hezits said you might want to check that you are indeed using bluetooth midi over a "short" distance. Electromagnetic activity can create a lot of problems so I would try a wired connection if possible. But there is hope:while away from my studio on summer vacation, I made some test with an iphone 11 using RTP midi over a dedicated wifi connection with a surprisingly low latency (around 10~15ms). My iphone 11 handled the CPU load without any problem even at 128 voices. I was even practicing an accompaniment over a pre-recorded flute solo playing from another app!

ps: I do not recommend using wifi RTP midi, as it adds timing randomness.

I just tried a Roland FP-30x at Guitar Center and connected it to my pianoteq 8 iPhone app, through bluetooth.  I have an iPhone 12. Sample rate of 48000 Hz and buffer of 128 samples. The latency was too high for live playing. Does anybody know how the iPhone latency will compare to a computer latency, if I connect through wired USB midi?

Are you sure you were connecting via Bluetooth midi and not Bluetooth audio?  The FP-30x allows both types of connections but they're for different purposes.  Bluetooth audio has lots of latency, but it's not a problem for the usual uses (e.g., to play background music into the FP-30x's speakers).  Bluetooth midi is pretty low latency, certainly most people are happy with it for live playing.  iPhone 12 is perfectly capable for running Pianoteq, faster and with lower latency than many laptop PC's that people use for Pianoteq.

Anyway. The iPhone app ui is really really hard to use, isn’t it? It’d be great if they made it follow normal iPhone design guidelines.

Does anyone know how to delete a preset on ios?

Go to Options /General/Folders  and you have access to the presets folder and can rename , delete, etc… like on the computer version. The advantage of the current  IOS UI is that the navigation is quasi identical to the computer version's one which makes it very intuitive for long time Pianoteq users.

Thank you!

I think Pianoteq and a modern iPhone or iPad are a great combination. Now if only the controllers would get better...

That adapter plugs into your phone, and you can then connect your digital piano via USB to the camera adapter, typically with a USB-A to USB-B cable (printer cable). Some of the camera adapters also have 3.5 mm headphone jacks (only necessary if you're not using an audio interface, and I believe the FP-30x has an integrated audio interface).

Latency isn't noticeable to me (wired) at all, I've played it on the iPhone 13. Playing experience is really similar to the PC.

How do you have a wired connection from a digital piano to an iphone?
