Deprecated HAL apis don’t mean they no longer wrk, just new features won’t be supported in the old driver model. They should still continue to function as they did (given there weren’t any bugs or regressions), so I do think it’s a problem elsewhere perhaps in usb and communicating to the hardware somehow
Tried it out on my machine running 10.15, definitely is an issue with the audio driver, midi seems to be okay.
Starting IO to the Virus audio device seems to be timing out by not getting the first zero time stamp. So definitely something up with the usb/audio driver, perhaps something incompatible with the 32->64 bit transition?
I wouldn't think this would be a difficult problem to solve if someone looked into it.
I have a TI2 that I haven’t used in years. I actually work at Apple in CoreAudio and will try this out on 10.15 and see how it goes.
but aside from that, is there any plans to open source the driver code if there is t going to be any future support going forward?
