Loopy multi-app audio mix
Using Loopy Pro's capabilities to do some level of interapp comms via Auv3, can I approximate some of what is shown here purely within LP (ie: without AUM or AudioBus), with iBassist running as an Auv3 effect within LP on one channel (basically going through a chord sequence) and sending input to other auv3 apps that might be running on other channels so they can react/follow the sequence while outputting their own sounds.

Your thoughts and pointers/urls much appreciated.
Thanks

Hi. You might want to change your title. "Interapp Audio" is the name Apple uses for the (deprecated) older method for music apps to communicate, before AUv3 was created.
That’s exactly what I thought from the title.
Done! Thanks @uncledave and @michael_m
@danm: fwiw, when an AUv3 is running, it is a plug-in. Apps are standalone entities whereas plugins are running as entities inside a host app.
What is it that you would like to know?
Was just wondering if I'd need to use Aum or Audiobus to accomplish similar to what's shown in the video or if I can accomplish similar entirely within Loopy Pro, having a plugin like iBassist, instantiated on a channel, push data to another plugin that might be in a different LP channel so it would play similar chords/notes...or would iBassist, when used as a plugin/auv3 w/in LP not provide the type of functionality shown in the video, but rather only support receiving input from my source inputs in LP or midi
@danm Does Chapter 5 of the Loopy Pro manual help answer your question? https://loopypro.com/manual/#mixer
Thanks @toneman88. I had read the manual end to end when I recently purchased LP. Re-reading that section just now was very helpful, thanks for the suggestion. To answer your question: It does help answer my question, as it makes me think (as I thought prior to my post) that I can do what I'm asking using audio unit inputs and midi inputs, but I'm just not entirely sure and don't have many plugins yet, so not that familiar with this area. Anyway, perhaps my question isn't clear enough but regardless I'll experiment at some point and see what's possible. Thanks
No problem @danm. Glad I’ve been some help. I don’t have iBassist or Loopy Pro (yet! It’s high on my wish list) so I can’t give a definitive answer, but I believe the answer should be “yes”, unless I’m misunderstanding your requirement. Michael (the dev of Loopy Pro) also developed Audiobus many years ago, long before Apple came up with AUv3 (and indeed Inter App Audio aka “IAA”). So, in this context Loopy Pro is like Audiobus +++ .
I think part of the problem in answering your original question still lies in your use of terminology - which is understandable if you’re new to all this. People on here will be very helpful.
You mention using iBassist as an “AUv3 effect”, but I think it can only be used as an AUv3 Source plugin. I haven’t sat through the 15 mins of Doug’s video, but I imagine that he has placed iBassist in the top “blob” of an AUM channel (i.e. a “source”) and then either routed the AUDIO data from iBassist through AUv3 EFFECTS in the blobs underneath in the same channel (e.g. EQs, Reverbs, Compressors etc.) and/or sent MIDI data sequences from iBassist to other AUv3 Source plugins on other channels WHICH ARE CAPABLE OF RECEIVING MIDI INPUT DATA in order to generate audio which can then be further processed by AUv3 effects in those channels. I’m guessing the latter situation is what you’re trying to recreate. As I say, I don’t have either app, but I’m pretty sure Loopy Pro will do that - provided that the target AUv3 source can accept MIDI input.
If you can give a timestamp in Doug’s video where he does what you’re asking for, people may be able to give you a better answer. I hope I haven’t confused you!
Yes, I think you're following exactly what I was asking about and I agree that my terminology was incorrect...should not have said "AUv3 effect", rather should have said "Audio Unit plugin".
The timestamp in the video I'm talking about is from 2:22 to the 3:00 minute mark. Here is just that snippet:

Your discussion around having other plugins that are capable of receiving midi input data is indeed what I was thinking will be the key to setting up the scenario I'm asking about. As I said, I'll do some exploring, but appreciate your sharing your thoughts!
Great. It’ll be even easier if you think in terms of AUv3 Sources & AUv3 Effects, rather than just AU Plugins. AU Plugins can be one or the other, or sometimes both, and it helps to be aware of the context you’re trying to use them in.
Anyway, it’s 04:30 here in the UK and I was having trouble sleeping, but I think I’m ready for another try now! I’m sure there’ll be better answers following me - good luck with your experiments.
And welcome to the forum.
@danm : the sort of thing you want to do can be done in Loopy Pro. I recommend spending some time watching some of the many videos people have posted about using Loopy Pro. There are some comprehensive video series that walk through all aspects of Loopy Pro and also various other tutorials and demonstrations people have posted of their setups.
The overall concepts are straightforward but figuring out what plugins you want to use and they work may take some time if you aren’t already familiar with them.
Basically, add anything that will send midi to Loopy’s mixer using Add MIDI. Add audio instruments to be controlled by MIDI using Add Audio Unit. Tap on the destination slot of MIDI sources to choose the destination for the MIDI,
What if it's an instrument, like iBassist, that also sends MIDI. Do you still need to use Add MIDI, or can you route the MIDI output directly from the instrument instance?
Yes. You can add midi and add the same instance of the audio AU. It is how the midi routing works for anything that sends midi
For example, if you want to use GeoShred as an instrument snd s controller, you load GeoShred as an AU then use Add Midi and choose the instance of GeoShred you already created.
