AUv3 Effects Bypass When Recording Starts
The effects work correctly while monitoring, but as soon as I press Record, the processing appears to be bypassed or reset and the audio starts recording dry.
If I open the FX chain while the recording is already running and reactivate the effect, it immediately starts working again and is recorded correctly from that point onward.
I was able to reproduce this several times using Apple AUReverb2, including with a very high wet mix to make the difference obvious. The audio input and routing are correct; the issue specifically happens when recording starts.
I also tested this on both an iPhone 14 Pro Max and an iPad 9th generation, and the exact same issue occurred on both devices.
Steps to reproduce:
1. Add and enable an AUv3 effect.
2. Confirm the effect is audible while monitoring.
3. Press Record.
4. The effect disappears and the recording is dry.
5. While still recording, reopen the FX chain and reactivate the effect.
6. The effect immediately returns and is recorded correctly.
It seems that starting a recording may be restarting the audio engine or route without properly re-enabling the AUv3 effects.

Olá! Obrigado pelo relato detalhado. A nova versão provavelmente já corrigiu esse problema. Se o problema persistir após a atualização, por favor entre em contato comigo por e-mail para que possamos aprofundar a investigação. Interfaces de áudio podem se comportar de maneiras diferentes, então é possível que seja algum caso específico que eu ainda não tenha tratado. Nos meus testes aqui, usando efeitos com uma Audient EVO 16 e uma Focusrite Scarlett 2i2, consegui monitorar e gravar o áudio com os efeitos normalmente. Obrigado novamente por reportar o problema!

Honest Feedback for Developer + Feature Request
1) You can’t exit the mixer in horizontal orientation on iPhone unless you restart the app entirely. Normally orientation turning is how you exit, but when your phone is mounted somewhere, you can’t always change its orientation. Please fix this! 🙏
2) External file save locations. I was surprised to find I am unable to save recordings to external drives. Please add support for external drives! 🙏
3) AppleLog / uncompressed recording! Please add support for it 🙏
4) Additional frame rate options would be nice! Notably missing is 24fps.
extra info: I was able to get my Arturia AudioFuse Studio interface hooked up to record my instruments + my mics. It merged the output file perfectly!
I hope to see this app receive continual updates- good luck devs!
Response from developer
Thanks so much for the detailed review and feedback! Really glad to hear Studio Camera is working well with your AudioFuse Studio setup! 1. Unfortunately, on iPhone the full interface with the tab bar simply doesn’t fit properly in landscape mode, which is why the mixer currently behaves that way. I understand that rotating the phone isn’t practical when it’s mounted, though, so I’ll figure out a better solution for exiting the mixer. 2. Saving directly to external drives is already on my roadmap. 3. Apple Log/uncompressed recording is something I’d like to support. I don’t currently own a device that supports Apple Log, so testing it will be a little difficult for me, but I’ll figure something out. 4. Additional frame rates, especially 24 fps, should be relatively easy to add. I’ll add that to the roadmap as well. Thanks again for taking the time to leave such a detailed review and for the suggestions! 🙏
Underrated app for AUV3 plugins
Response from developer
Thank you so much for the review! That's an awesome signal chain you've put together! It's great to hear the host is handling eight AUv3 plugins without any issues and that the built-in NAM app fits so well into your guitar rig. One of my main goals was to make it easy to build complete guitar setups on the iPad without compromising performance, so it's really rewarding to hear it's working well for you. Thanks again for your support, and happy playing!
Polished app, but work in progress
A steal!
I use NAM files for my live electric tone and this seems to have less of a DSP spike than NAM XT and Gigfast light when switching NAM files. Both great apps, but I have a stacked AUM project and a fairly cheap iPad. I can’t recommend this app enough!
Response from developer
Thank you so much for the kind words. I'm really glad it's working well for your live setup. Keeping DSP usage low and making model switching as smooth as possible were major goals during development, so it's great to hear that it's making a difference, especially in a large AUM project on a more affordable iPad. I really appreciate you taking the time to share your experience and recommend the app. Feedback like this motivates me to keep improving it. Thanks again!

Response from developer
Thank you! I'm glad it's working well for you in Loopy Pro and other AUv3 hosts. The Tone3000 integration was something I was really excited to add, and it's great to hear you're finding it useful. Thanks for taking the time to share your experience!
If you play guitar on iOS you need this
Response from developer
Thank you so much for the amazing review and support! It really means a lot—especially as an indie developer working on this in my spare time. I’m glad you’re enjoying the Tone3000 integration and getting great results with it. More features and improvements are on the way!
Can’t wait to see what other plug-ins you add to this app
Response from developer
Thank you so much for the 5 stars and for the kind words—it really means a lot! I’m glad you’re enjoying the app. “Fresh Air” is a great suggestion, I love that plugin too. I can’t promise anything specific, but I’m always exploring new ideas and integrations to expand what’s possible. Stay tuned—there’s more coming!
Neural Amp Modeler!!!
Response from developer
Thank you so much for the 5 stars and for highlighting that—it really means a lot. I agree, the AUv3 version of Neural Amp Modeler is a big part of what makes the app special, and I’m glad you’re putting it to good use in apps like Loopy Pro, AUM, and Cubasis. Hearing that it’s delivering great tones on your setup is exactly what I was hoping for when building it. There’s still a lot more I’d like to improve and expand, so feedback like this helps a lot. Thanks again for the support.
