I’d like to run LFOs out a couple of the outputs of my ES-8 from iOS Audulus into my Eurorack, while at the same time using output 1 for a piano sound coming from either Garage Band or another app.
I have no problem getting an LFO out from Audulus, but every time I move away from it to another app, it stops communicating with the ES-8. What am I doing wrong?
I tried running it as an IAA in AUM. No problem getting VCOs out via a stereo out into the channel (which is then routed into the ES-8), but the same setup does not seem to work for an LFO.
When Audulus is running as an IAA or Audiobus app, it has no direct connection to the ES-8. The host app e.g. AUM has the connection to the audio hardware. It’s possible that AUM won’t pass very low frequency audio. I don’t have an ES-8 so I have no way to test. @robertsyrett has a couple and can probably give us a definitive answer. You might try Audiobus as an alternative. I believe that even if you have Audulus configured for background audio that a foreground app that is competing for the audio out will take priority over the background app.
