Auv3 virtual Mac Audio Unit host

I know that this is probably for many reasons an idiotic idea and a non starter or it wouldn’t be so difficult to rebuild apps for auv3… but I was just wondering what would prevent an iOS auv3 app that ran as a virtual Mac audio unit type host? So you could run Mac AU vsts in the virtual host and then the host app as an auv3 in iOS logic etc

why do I have the sense I’m suggesting something idiotic 😂

I mean we have emulators for consoles and gaming

  • It’s not an idiotic idea at all. I think we all pray for something like this to happen, that somewhere a developer builds a loophole so we can run vsts in our hosts. That would be the day and I predict that developer is going to earn some good money with that. I will be the first buyer!

    Unfortunately it doesn't work that way. You can't have wrapper plugins like you can desktop. This is an Apple limitation. Just like you can't host an AUv3 in Drambo and then host Drambo with another AUv3 host like AUM. You can only go 1 layer deep.

    Also, desktop AUs have licensing and installers, those are obviously not available on iOS.

  • There are people working on similar things. Not sure if this works for any audio apps https://github.com/PlayCover/PlayCover

  • Don’t forget, they said it was impossible to escape from Alcatraz.

  • I think something like that would be great but I think desktop plugin developers wouldn’t want their apps ported to iOS thru a third party plugin and not be financially compensated.

  • It's not an idiotic idea at all. It's a perfectly reasonable thing to hope for.

    But it's also not possible. As mentioned, an AUv3 plugins can't host other AUv3 plugins. The capability is just specifically not there in the way AUv3 is architected.

    (btw - VST isn't a generic term for plugins. There's no such thing as a "Mac AU VST". There are Mac AU plugins and Mac VST plugins. The terms refer to the different ways audio apps can be "wrapped" (not a very accurate term) to work inside hosts.)

  • I’m still struggling to understand, what exactly does @wingwizard want?

    To run Mac AU/VST binaries in an AUV3 wrapper on the iPad…

  • Isn’t the Mac format of Audio Unit plug-ins AUv2?? In theory, it could be possible some way or another. Only AU on Mac use installers (like dmg files) and different licensing compared to iOS counterparts. It’s kinda complicated and a mess, but I do think Apple deprecate IAA not for nothing.. And Apple themselves bringing Logic Pro to the iPad and even advertising some well known plug-in makers that are also available for iPad lefts me wonder..

    Interesting, with what neo8 said about logic. I mean, if we couldn’t have auv3 hosting a plug-in (it wouldn’t be auv3 hosting an uv3 though, rather auv3 hosting a vst/mac au, probably no différence but thought I’d mention), would that mean that a daw could still host, or be the viable way of hosting vsts? I mean, a wrapper needn’t be an auv3 itself, if it’s just a bunch of code, and could be built into a daws handling of plugins. Or…

    Thanks re vst meaning - I think I’d got used to hearing it contextually, so good to know.

    I do see the vested interests being the more significant factor. I mean, I can’t really see why vst etc devs would object to ot, it would be more sales of the same product. But Apple as always will render unusable anything they think might present the slightest shadow of a chance of interfering with their absolute control of every possibile avenue of potential nano-profit/giving users a better experience

    But if for example, Drambo hosted the vst, contained teh wrapper code allowing it to do so? I realise not the initial way I phrased it as I didn’t understand this limitation. Uhhh. Haha. My head hurts.

    I suppose now all I’m talking about is coding to allow vsts on iOS, and the practical reasons thsi isn’t possible, which is probably something very complex and to do with so code, or related to everything being controlled by Apple run through the AppStore.

  • The CTO of Reason (Propellerheads) gave a presentation showing that they had created “stubs” for the Reason Store to be able to download Reason Exchange “Products” to run on IOS and even webpages. It would have created a new market for Reason and all Exchange developers to benefit from this strategy but quickly Reason hired and new CEO and the idea never got wings.
    So, sad. Imagine of we could purchase all that Reason Exchange content for re-purposing on IOS. There could be Reasons that it would be a nightmare for support but still the idea was a “game changier” (typo is intentional for long time members with good memories).

    Thanks... Can you post the link to Stubs?
    Was thinking of an AUV3 hosting IAA apps. I think Steinberg had such a product for their early VST.
