(3rd Party Issue) AUv3 Resizing Issues

[fixitmania53]

Hi Lars,
I have just purchased the newly released OB-Xd synth app but there is an issue with it not resizing correctly when used in AUv3 mode. I have contacted the developer and shared photos of the issues I am experiencing, their response was as follows:

From your description, it appears that the DAW may not be fully recognizing the set size that OB-Xd outputs to the host, which could be causing the interface display issues you’ve encountered. Given this, I recommend reaching out to Steinberg support for further assistance in resolving this compatibility issue.

Please see my photos below, the top photo shows my 13” iPad Air M2 with OB-Xd expanded to full size, when the keyboard is closed the OB-Xd UI remains the same small size and cannot be expanded further.
When using the Air 4, the on-screen keyboard covers the bottom section of the UI, there is no access to the bank and preset window, also the bottom two rows of controls are hidden behind the keyboard. I am using iOS17.6.1. on both iPads. Cubasis v3.6.6
Any help would be very much appreciated.
Thanks.
Mike.

Hi Mike,

Thanks for your message, which I’ve discussed with our engineering with the following outcome:

What happens if you tap the full screen button in Cubasis (the 4th button from the right, next to the “R” button)? Is OB-Xd’s UI fully visible then, now that the keyboard has disappeared and OB-Xd has been informed by Cubasis to switch into full screen mode?

In general, most Audio Units have adaptive UI layouts that adapt to whatever size the host (DAW) constrains them to, given that the aspect ratio isn’t too crazy. Cubasis puts Audio Units into a view that has a wide aspect ratio and is about the size that Apple’s examples suggested, when AUv3 for iOS was introduced back in 2015. Audio Units that require a square or portrait aspect ratio need to either implement internal vertical scrolling (many do), or else they will only be fully visible in Cubasis’ full screen instrument mode.

Best,
Lars

Hi Lars,
I have attached the three different screen displays of OB-Xd open, this is the largest it will expand.

1. When first opened.
   

   

2. With the 4th from right button pressed.
   

   

3. Expanded view (list/brows button pressed)

Thanks @fixitmania53,
and shared with our engineering…

Worth to note here is that currently OB-Xd v3 (V3.5.7 at the moment) uses a ‘Fixed Size UI’ and thus doesn’t dynamically scale to any view-port size given by any host, this is not specific to Cubasis.

[fixitmania53]

Hi Samual,
The only problem with the fixed size UI is when using OB-Xd with iPads screens smaller than the 13” is you are not able to have both on-screen keyboard and OB-Xd displayed at the same time in Cubasis without the bottom three rows of controls and the preset bar completely covered.

That is something discoDSP has to fix as their AUv3 doesn’t adapt to a larger than normal view-port.

[fixitmania53]

This takes us back to the start of this topic where discoDSP states it is Steinberg that has the problem:
DAW may not be fully recognizing the set size that OB-Xd outputs to the host

[Samuel_Lindeman]

It’s a typical ‘blame the other party game’ (and it’s not their first time).

The AUv3 plug-in should adapt to the view port size the host gives it, not the other way around, that’s the way it works on iOS/iPadOS.

[fixitmania53]

@Samuel_Lindeman

that’s the way it works on iOS/iPadOS.

That makes perfect sense. Considering discoDSP are issuing daily updates hopefully they will put it right.

Hi @fixitmania53

I’m glad to send discoDSP a short message regarding the fix to be made on their end. However using their webform requires entering an order number which I do not have.

Best,
Lars

@LSlowak You could try directly sending them an e-mail at this address?

As I’m personally mostly using LogicPro for iPad as a host I’ve had to (on the 11" iPadPro) resort to increasing the iPad display size under Display settings to ‘more space’ so I can see the full plug-in UI and the on-screen keyboard at the same time.

In Cubasis I can NOT do this since it’s currently not possible to re-size the on-screen keyboard when a plug-in view is open (I know the Cubasis keyboard is re-sizable but the size is seeming locked when viewing a plug-in?).

If you mange to somehow reach the developer ask him to add a pan & scroll option to the plug-in when it doesn’t fit the current view-port. I know he can do this as his other apps already do (The OB-Xd previous version and OPL both can be scrolled when it doesn’t fit into the current view).

Personally I will not spend more time on troubleshooting this issue.

Take Care & Stay Safe

Hi @fixitmania53, Hi @Samuel_Lindeman

Thanks for your messages.

I’ve managed to use the web form, and shared the feedback from our lead engineer regarding how to fix the issue with discoDSP.

Best,
Lars

Hi @fixitmania53

I’ve shared the reply from discoDSP via PM with you, who are committed to resolving the problem as efficiently as possible.

Hi Lars,
Just to let you know that the OB-Xd GUI resizing issue has now been resolved by discoDSP.

Hi @fixitmania53

This is great news, thanks for the update!

Best,

[Samuel_Lindeman]

Well, it’s ‘almost’ solved!

When you bring up the on-screen keyboard the preset selector will be hidden behind it and there’s currently no way to re-size the on-screen keyboard when a plug-in is shown…

The on-screen keyboard can be vertically resized when no plug-in is shown.

@LSlowak If possible, please allow vertical resizing of the on-screen keyboard when a plug-in is shown! (It can already be re-sized when no plug-in is shown).

Cheers!

This looks like your suggestion is the only option unless discoDSP can add vertical scrolling to their GI.

[Samuel_Lindeman]

Yep! Many developers add vertical scrolling to their plug-in UIs when the plug-in doesn’t fully fit into the give view-port size and ironically the rest of the discoDSP plug-ins already offer vertical scrolling…

But I guess with all these ‘desktop ports’ popping up the developers simply don’t take enough time and care to adapt their stuff to mobile hosts limited view-ports and almost expect the host to have some kind of window management (Like AUM, apeMatrix, Drambo, LoopyPro, ZenBeats etc.).

Being able to re-size the keyboard in plug-in view in Cubasis is still a valid request as it can already be re-sized when no plug-in is shown.

Support for floating plug-in windows in Cubasis would be nice but I don’t see that happening in any near future…

[LSlowak]

Hi @fixitmania53

Does the OB-Xd presets show up in Cubasis’ preset list, as it is the case with many other 3rd party plug-ins?

Thanks
Lars
