Please suggestion on some AU instrument capable of sampling from HOST audio
I mean is there something like that ? I though when i load KOALA into AUM as isntrument and try sample audio - it will work.. but it does not work .. neither in Cubasis ..
Any combination of ANY AUv3 instrument and host where this works ? Or i am just doing something wrong ?
Comments
Koala can sample host audio, it just needs to be an FX AuV3 that is receiving the main audio stream. Put it pre-fader on the master track and you should be okay. Instruments cannot receive audio by themselves.
Oh, sure, that makes sense... I thought so too, but AI kept telling me that Instrument can also register the audio input :-)))) Thanks, I'm going to give her a good telling-off for hallucinating again

Instruments cannot get audio from the host in most hosts. AU need to be loaded as FX to get audio input in most hosts. Apparently, there is a way for audio instruments to get side-chain input but I don’t know of any hosts that support that. (I only know about it because Pianoteq 9 has that feature and Loopy Pro inadvertently sent audio to it.)
Instruments can receive audio from the host if it has the means to route audio to them which AUM can't.
(The AUv3 Instrument also has to support Audio Input which unfortunately many don't).
When using for example MorphWiz 2 on a Midi Track as a regular Instrument in LogicPro for iPad I can still 'side-chain' audio to the Instrument from directly from an external source or another track in LogicPro for iPad for sampling...
...the problem here is that GarageBand has issues (ie. hard crash) with AUv3 Instruments that support audio-input and thus it's not widely spread but is definitely technically doable...
As for sampling Koala, loading it to an FX slot works as mentioned...
...some day I do hope that the Koala AUV3 Instrument will get support for audio-input...
Been using Rob Jackson's simplooper on my instrument and bus chains. Super quick
I believe the new app choppy can do this as well. Actually there’s a bunch as long as you load the app as an audio fx to make sure the audio gets passed through it on its way out.
OK intereseting .. so it actually IS possible .. so MorphWiz2 positively can process input audio from host AND work as Instrument, yes ? It's a little costly but worst case i pay it .. i need somehing which 100% works somewhere, to test implementation in my little personal project
App choppy ? Can you give link to app ? Also - is Logic solid enviroment where it should work or you do use other HOST ?
That's right, I had a blast doing beta on it prior to its release...
...sure there are things I would have done differently but it is what it is.
You could shoot the developer an e-mail (He's a cool Dude) and ask?!
https://www.morphwiz2.com
(There's a contact e-mail at the bottom on the page).
You could try creating a 'Dummy Instrument AUv3' with Audio Inputs and test with that?
(Hosts like LogicPro for iPad expose the input options in the plug-in view when the Instrument has support Audio-Inputs).
Mela doesn't yet support Audio Input in the 'AUv3 Instrument' but passing audio to the AUv3 Effect definitely works.
That could be a 'free' plug-in to test audio-input with?
(I'm quite sure @Nikolozi knows how to add Audio-Input support to the AUv3 Instrument instance as well).
Cheers!
At one point, I added audio input support to Mela's instrument AUv3, because I liked how Logic Pro allowed side-chaining in instruments. And so it worked great in Logic, but Mela stopped loading in GarageBand for iOS. So had to revert it. Pretty sure, it was a bug in GB. Probably fixed by now, I should check.
But I wasn't too worried Instrument AUv3 not having audio input, because the Audio Effect AUv3, more precisely Music Effect AUv3 (that's what Apple calls it), allowed Mela to have not just 1 but 2 audio inputs, in addition to MIDI input. And Logic Pro and AUM handle the Music Effect type, and Mela users can use instrument presets fine in them.
well i can do that but i want avoid that i fucked something in that dummy instrumment lol :-) so i am searching for some 100% solid working solution where i am 100% sure if something is fucked it's on my side
I think that's a dilemma every single developer faces at some point...
...ie. being able to write 100% 'un-fucked' code
My mistake, it’s actually called Choppa, I don’t have it, but it’s a new app, and it specifically mentions recording audio directly into the pads/slicer.
sEGments would be another option, for a sample slicer with fx, etc…
I do remember tho that someone mentioned this doesn't currently work in the AUv3, they weren't sure whether it was a bug or what...
@dendy you'd best just use Koala loaded as an fx AUv3, you already have the app anyway, right?
Right on, thanks for the heads up.
... and after all that to Enshittify (re-Enshittify?) it.
Way more than two. Loopy Pro AUv3 FX allows 32 stereo inputs freely routable to 32 stereo FX outputs. miRack offers 16 mono / 8 stereo.
My problem solved, i made it work.. again publicly thanks to Nikolozy for a help !!
Awesome! This thread pushed me to bring back side-chain support to Mela's instrument AUv3, and GarageBand for iOS now seems to load it fine.
In theory, all AUv3 types (including Generator, Instrument and MIDI Processor) can support as many audio and MIDI inputs as they like, but not all hosts support all configs. e.g AUM doesn't allow audio input for instruments, and Logic Pro doesn't allow MIDI input for the Audio Effect type (it must be a Music Effect type).
Here is the full list of all types for those who might be interested in: https://developer.apple.com/documentation/audiotoolbox/1584142-audio_unit_types
And of course, Apple only documents these things in C header files, so here it is if interested: https://github.com/hexops/xcode-frameworks/blob/8a1cfb373587ea4c9bb1468b7c986462d8d4e10e/Frameworks/AudioToolbox.framework/Versions/Current/Headers/AUComponent.h#L140
You can see Apple tries to indicate which types can have which audio and MIDI I/O, but thankfully, iOS developers have been more flexible than that. e.g. allowing MIDI I/O for the Audio Effect type.
thanks, will check it and verify if my little experiment correctly support everythning of this
I’m pretty sure Pianoteq in Logic Pro allows for side audio input to produce sound as if the instrument is resonating from external audio. I know it works with Pianoteq 9 on Logic Pro but I don’t think I’ve checked on iPad. Still, I think that’s a really cool feature.
