    IAA though defecated, would also allow recording in hosts.
    I’m I right to assume that since it is sort of the basic routing architecture used by apple, that it should be simpler to implement?

    I’m sorry but I can’t just ignore “defecated”. :)

    I took this one from an Haq attack episode, I confess.

    However I mentioned many times before is that the main reason why I don't rush to add IAA/AudioBus support is any potential performance issues.

    miRack's excellent performance is achieved by using two audio processing threads working at high priority. So both cores on non-Pro iPads are taken and not too much CPU resources are left for other audio apps.

    I understand that 1. iPad Pros have 4 cores, so this should not be a problem at all, 2. recording and other simple audio processing should be fine even on 2-core devices, and 3. it's up to users to not create patches and IAA configurations that their hardware can not support. However, people will still complain about it. I can not limit IAA to audio recording only or to Pro models only or to small patches only, so I do not want to add it until I make sure that the user experience will be good in all usage scenarios. Please understand.

    Good points, no arguing with that.
    As for recording: What about a module that can record to different files and be controlled by different gate inputs?
    One to toggle record/stop/record&append/stop/record&append/...,
    one to create a new file,
    one to toggle play/stop.
    Why this way?
    In order to make beat-synced and slice-able recordings (by use of appended recording) which would allow for direct import of the resulting files into other apps. The module would need something like an "Open in / Share" button too.
    Would this be possible?

    Yes, this is a cool idea that I'm ready to implement.

    @mifki I keep accidentally moving modules that I don't want to move... then it gets kinda fiddly to move them back. Once I get them were I want them... wish I could sorta temporarily lock them down or something.

    There's a Lock Modules option in the Tools menu.

    Is that coming soon or something? I don’t see any Lock Modules in the Tools menu.

    Uh-oh... looks like App Store is having a problem. Version 1.02 that I've released 10 hours ago is still not live.

    This got my full attention. There is overall consensus (at least it was till yet) that iOS is limited to single realtime audio thread.

    So this sounds like you managed to do something impossible :-)

    Version 1.02 seems to be available now.

    No, hosts can do it fairly easily. Instead of calculating the output of several discrete plugins sequentially, you can also do them simultaneously (if they don't have interdependencies). Same probably goes for "modules" in this rack setup. It's when you want to do it inside a single plugin that it becomes really difficult/impossible to manage.

    Although using GCD is unsafe.

  • mifkimifki

    Yes, since there's a lot of modules, they theoretically can simply work in parallel. In practice, though, it's not that straightforward because modules need to pass data between themselves each sample, and normal means of thread synchronisation do not work at 44kHz rate. But there are some ways around it.

    at what sample rate does the modules run at?

I'm not expert in DSP coding, my knowledge is just rough (still learning, one day i want to move to this highest level of coding art :))), but as far as my understanding goes, sample accurate mixing is needed also for output of individual plugins ..

    Sorry if i wrote something totally wrong, i'm hungry to learn so feel free to go deep :)

    Not sure how sample-accuracy fits into this story? At least with AUv3 you don’t process plugins sample-by-sample but buffer-by-buffer. The mixing happens after that. B)

    Are there any other music apps that use multitouch gestures for UI actions? All the apps I'm aware of use multiple touches strictly for performance, such as playing keyboard or custom controller or kaos pad. Looking ahead to AUv3 hosting (or being hosted), I think it may be wise to avoid reliance on multitouch gestures to drive the UI. (And of course I keep harping on pencil compatibility -- sorry! But speaking of breaking the flow...)

    Yes, iVCS3 allows both scrolling and multitouch gestures so you can turn multiple knobs and play the keyboard as well simultaneously. To scroll you use one finger in a blank portion of the panel. @mifki should definitely check this out as a well executed solution. Perhaps set pinch and some to ignore knob, slider, switches and other UI control areas. iVCS3 by apeSoft

    It seems ok. I hacked together some garbage patch pre update, re-downloaded it (had removed it) and opened it up, my patch was still in the cloud and opened right back up. So I think it's ok.

    Working good here on an iPad Air 2. In fact, I’m actually surprised how well the OS is working in general. Nothing got totally broken from the update. A few apps working a little sketchy, but that probably gets fix with an update from the devs themselves. But yes, miRack working good on iPadOS 13.1 for me*

    *results may vary

    In this case, there's no "mixing". Modules process a single sample (or in general perform a single step of whatever they're doing) at a time, then outputs are sent to connected inputs. Audio output module is just a normal module that writes to an audio buffer which is then returned to the OS.

    The problem with multithreading is how to implement modules pausing and waiting on their inputs to become available so that whatever mechanism is used for this, doesn't use more CPU than modules themselves.

    I’ve got a simple question. Is there UNDO?
    Thanks for a double tap to reset.
    Also wanted to ask, would be there anything like core audio?

  • [Deleted User][Deleted User]

    Undo would be a good feature for this app.

    Great news. I just got email that Floats (Maths clone) avaiable in VCV 1.0. And dev says it was released under GPL v3 license so everybody allowed to use his code with custom panel design.

    Any plans to add the Bidoo modules? Love the dTroy and bordL sequencers, based on the Intellijel Metropolis.

  • david_2017david_2017

    Wow the possibility of maths and entropia... 😮 looking really good !!!

  • mifkimifki

    GPL will not do.

    Bidoo developer requires explicit permission to use their panel graphics, I need to talk to them.

    I can not comment on the possibility of adding Entropia or other Geodesics modules at the moment.

    Not sure what he meant by core audio, but a way to set buffer size/sample rate/bit depth would be welcome.
    While I'm amazed by the amount of modules I can run on my Air2, once another app is running in background it glitches regardless of patch complexity, which could be because of audio settings mismatch.

    While you are at it - audio recorder -, an audio playback module would be nice too :)
