Yes. I have actually recently switched my ID44 to standalone mode.
I basically just wanted a portable 4 ch analog preamp without bringing 19" rack gear with me.
I am recording to a digital recorder at the moment (Tascam Studio Bridge -Dawless). So this was a neat solution for me to stay out of the box.
Many thanks to Audient's support. I didn't know how to set up the ID44 to do this. I sent them one email and they sent back pics and instructions right away! Thanks again, Tom!
From Audient:
"Hi Paul,
No problem!
In that case, first, open the iD mixer go to "view" > "show system panel" and set the 1/2, and 3/4 outputs to CUE MIX A and B respectively as seen below;
Now open close the system panel and select CUE A from the right hand side. Raise the CUE master output to 0dB, and raise the fader for mic 1 and 2, pan them hard left and right as seen below;
Now Open Cue B and repeat these steps, but swapping the mic channels for 3 and 4 as seen below;
Once this is complete TRS output 1-4 on the back of the iD44 will send out mic preamps 1-4.
Now go to "setup" > "store standalone state" to save that for using standalone!"
