Sound Input question

[JJHP3]

Hi Folks

Up against a problem of getting input from my MOTU Ultra lite interface. Capture audio works OK. I can see the green meters moving and it is showing my 8 inputs. Sound Freq Watcher ++ works OK. Sound Freq Watcher and Sound Level Watcher don't work. What I would like to have happen is Sound Input provides 8 chls of sound to the AUMixer or AUMixer3D. Here's what tried and what warning sign shows up every time.  Any advice appreciated!  - John

Dear @JJHP3,

I can't test this myself right now because my MOTU is packed away. But I think the AUMixer3D has a channel limit. Disconnect the link between the Sound Input actor and the AUMixer3D. Try changing the SoundInput actor to 2, and then reconnect. Then try the same with 4 channels and 6 channels and see if that is possible. Somehow I think it only does 2 or 4 channels of input.

If that doesn't help, change the output configuration to Quadrophonic in Audio Midi Setup and try again.

Best Wishes,

Mark

Thanks Mark for taking the time! Some audio things work and some do not. Stripped down to the basics, I can't get any sound input from the MOTU using Sound Input. What am I doing wrong here?

Thanks, John

Hi John,
Sorry if this seems too obvious, but did you already check the settings from Isadora's menu bar under Output/Sound Output Setup? I know these are outputs, not inputs, but it may help to set up 8 dedicated output channels for the MOTU... or it may make no difference. But is worth a try. Core Audio actors sometimes need functioning outputs in order for the stream of audio to run.
Cheers,

ps.. mini disclaimer... I am more experienced with video.. not audio!  ;)

Valued fellow users -

For some reason, Sound Input started working this morning after almost a week of fiddling. Not sure why which makes me a bit worried about an installation I'm working on, but sometimes stuff happens in a positive direction. Go figure...

Thanks for you ideas - I'm sure one of them made it function!

Dear @JJHP3,

I'm glad you got it working. And for @primaldivine (and everyone else) the Sound Output Setup option only affects the Sound Player actor. It has not effect on Core Audio.

Best Wishes,

Mark

thanks mark.
@JJHP3 Since the solution you found remains still a bit mysterious ;) I thought I'd mention incase you have trouble again, that the Audio-MIDI set up info is on page 140 in the Isadora Manual, which you can grab from the troikatronix downloads page.

Thanks primaldivine. I've read the manual many times...  Still investigating reason for difficulties and will let the community know if i discover something of use.
