Hey, just tried the op1f (fw1.5.0) and op1(2.4.6) with s23ultra as you described, recorded with the preinstalled Voice Recorder app, and both work great as a stereo usb mic, tried with master mixer on op1f/op1og to mute left and then to mute right channel. Then it replayed on the phone with the same stero effect.
Just make sure you switch the recording mode to stereo mic on the app (default is mono).
What I am sad about though is the mono FM Radio RX/TX even on the op1f, where I had high hopes for stereo, not sure if some futurefw might help there.
I used the Field’s USB C cord into my iPhone (Animoog app). Midi is working, audio scoming in fine when I press orange mic button. Problem… I can heard the synth or drum audio under the app audio.
Universal audio volt 2 doesn’t work. I read on a reddit page that the Roland Go Mixr should work as an audio interface for the OP1. I am considering trying out arturia minifuse 2 , but will have to buy it first. Anyone tested it already?
For me no problem with audio and MIDI in and out with Ipad
Since the last update UA Volt 2 works! Seamlessly. Monitoring works, input work. Only downside is you cannot force the input to be mono/stereo. So recording input 1 puts it left. Now that they have their AMP engine connecting a guitar directly in the OP-1 seems to be just as good as putting an interface in between. But in theory I could hook up my phantom powered mic to the op-1 field.
