Hi @bvg73

thanks for your answer.

The system audio output is set to the MOTU as default. 

i am not familiar with using Qlab, just opening it, it offers a 14 Channel MOTU but I wouldn’t know how to route it.

Reaper recognises the channels too and I can address each speaker individually.

Hi @juriaan 

thanks for your reply.

1. No other Audio Software is in use.

2. Attached the screenshots

3. In Isadora 4 everything works as expected, it recognises the 10 channels of my MOTU Sound card.

@Juriaan asked all the right questions.

There were fixes implemented in Isadora 4, so checking how things look in that version is an important suggestion to follow and report back on.

But Google's AI brought up several points about MOTU CueMix FX software. So while you've likely seen the same response, here is what it said:

If your MOTU UltraLite MK3 is only showing two channels when more are available, it's likely due to incorrect routing settings within your software or the MOTU CueMix FX software. Here's how to troubleshoot and fix this: 

[SKIP TO CUE MIX RELATED TIP]

2. Verify MOTU CueMix FX Configuration: 

• Mono/Stereo: Make sure you haven't accidentally set all inputs to mono, effectively reducing the number of visible channels.
• Mixer Settings: In CueMix FX, check the "Mixes" tab and ensure the correct mix buses are assigned to the desired outputs. MOTU tech support notes
• Muting: Verify that all input channel faders are unmuted and that you haven't accidentally muted any channels.
• Advanced Mode: Some users have found that switching CueMix FX's monitor mixers to "advanced" mode reveals all channels, Reddit so try this if necessary.

Hi, don’t have the unit myself but these quick things to check have helped me at times across various devices: (in no particular order)

Set the system audio output to the MOTU as default. Then restart Isadora.

Try launching Isadora using Rosetta.

Test the audio routing in QLab. Just make sure the MOTU is set as the default output in macOS, if you’re not using a licensed version.

QLab and Isadora are pretty different beasts, but they both rely on CoreAudio under the hood (if I’m not mistaken), so it’s a good way to rule out OS or hardware issues.

Hope one of these helps!

Best

Could you try to install Isadora 4.x in Demo mode? And report back to us or that resolves your issue?

 Yeah, this is the only thing I can think of besides checking if there's any sort of configuration that can be done on your hardware using the hardware itself or via a dedicated app.

Unfortunately, we can't test Isadora with every piece of external hardware, so there are some oddballs out there that may not work.

Hi!

I asked our technical support team to look at this forum thread and get back to you.

A few troubleshooting steps that you could try:

1) Are you sure that no other audio application is still open, and just Isadora 3?

2) Could you provide us with a screenshot of the MIDI / Audio setup in MacOS? So that we can see how many channels are detected by the OS?

3) Could you try to install Isadora 4.x in Demo mode? And report back to us or that resolves your issue?

Hi,

I'm setting up an installation using 6 speakers — two of them split left and right — for a total of 8 audio channels. I have an issue with multichannel sound output in Isadora. 

I'm working on a Mac M1 Max running Ventura, and Isadora 3 (latest version). My sound interface is a MOTU UltraLite MK3, which has 10 analog output channels. In the Audio/MIDI settings, all speakers are correctly recognised and output sound as expected. Reaper also routes sound to all channels without issues. 

In Isadora, I get a yellow warning stating that the interface only supports 2 channels, which isn’t accurate — the system itself detects all outputs. Isadora only allows me to select 2 channels for output. I tried the sound player, AU Player and Movie Player.

Is there a way to enable multichannel audio output in Isadora with this setup? I thought it should be possible, but since the software doesn't seem to recognize the full range of my interface, I’m unsure how to proceed.

Any help would be greatly appreciated — the opening is this Friday, so it’s quite urgent.

Thanks in advance!

I might try installing ISADORA 4 and see what happens.

 4 includes a fix or two that address a stage freeze that was occurring on Windows in specific cases, so it may help.

@dusx Thanks for coming back to me.

So The PhysX is set to the NVIDIA.

The stage is sent to a 4K Dell monitor, which seems to be the only one seen by the  NVIDIA GPU. The integrated laptop screen is not listed. I also set ISADORA to use the NVIDIA card in the general windows settings.

I've also detected other issues.

I have a slightly intensive 6" transition (that works fine on my old 2070). It involves a 3D object being displayed on both scenes, different, not very intensive shaders, one at each scene, as well as 3D particles on the second one. More often than not the stage freezes during this transition, even without switching to any other application.

I'm leaving today for the Gig and I'm not taking the new computer with me. But saturday night I'll be back. If there's any test you want me to try, just tell me and I'll  be happy to do so.

I guess it is indeed related to the handling of the graphic cards rather than an ISADORA issue. I tried disabling the Intel graphic card but it dit not help. I then uninstalled it. For some reason Isadora refused to start after that, saying that it only had OPEN GL 1.1. I reinstalled the NVIDIA drivers... but the intel card was also installed automatically installed at startup.Did not insist any further.

I might try installing ISADORA 4 and see what happens.

Cheers

i used this keyboards as a button can be reprogrammed as a midi device with the arduino ide
