iPadOS 16.1 (20B82), iPad Pro, 3rd generation, MTFR2FD/A.
Cubasis 3.4.3
Syntronic, SynthMaster 2 and other up to date stereo synth audio units are mono, if the host is Cubasis 3. If the host is AUM, the synth are stereo, as expected.
Not tested with an external USB audio device. I did not test audio tracks. IOW tested with internal speakers only and the only audio sources were those audio units.
We are unable to reproduce the problem, same as Bulent from KV331:
“I just tested with both SynthMaster One and 2, in both plugins the output was stereo. I changed the panning of the oscillators to left and right and it was fine.”
In my testing, the project reloaded fine as well…
If the problem persists, please get in touch with Bulent directly.
you seem to misunderstand, this happens with many tested synth plugins, not just those of one vendor. The plugins are full stereo when using them with e.g. AUM or Auria Pro. They are most of the times mono, when using Cubasis 3. It’s probably related to the iPadOS update. However, from the hosts I tested only Cubasis 3 is affected.
Please share a clip with me which shows the exact steps leading to the issue.
Ideally, a simple project setup would be great to allow the team reproducing the problem.
Please upload the video via Dropbox or similar and provide me with the download link via private message or here.
As already pointed out by my first post, the issue was noticed with iPadOS 16.1 (20B82), iPad Pro, 3rd generation, MTFR2FD/A, Cubasis 3.4.3 using the iPad speakers.
In the meantime the iPadOS version and Cubasis 3 were updated to iPadOS 16.2 (20C65) and Cubasis 3.5. When adding the audio units the output was stereo after closing and opening Cubasis 3 the signals are mono. Restarting the iPad gains nothing.
The issue is still the same whatever AU synth is used. By the internal speakers the audio output is mono, if I connect an USB audio to headphone thingy from Delock with a Realtek ALC4040, the audio output is mono, too. If I connect an USB audio interface Scarlett 18i20 2nd generation and listen by channels 7+8 or channels 1+2 the output is stereo.
IOW if internal audio is involved either by the build-in speakers or by an USB thingy there’s an issue with the only available channels 1+2. If I connect a complete external audio interface channels 1+2 work as expected, as well as 7+8. I didn’t test the other channels.
Just curious but…
…Is ‘Studio Quality’ (ie. Measurement Mode) enabled in Cubasis?
If it is that would explain the mono output when using internal speakers or headphones on a stereo capable device as stereo only works when iOS processing is enabled.
