Here is what Catalina's System Report says about the MIDI interface connected through the Apple Pro Keyboard (which came with G4 Cube): Hub in Apple Pro Keyboard: Product ID: 0x1002 Vendor ID: 0x05ac (Apple Inc.) Version: 1.00 Speed: Up to 12 Mb/s Manufacturer: Mitsumi Electric Location ID: 0x143214...

Oops, my bad.
Runs happily when launched by the sudo command under Terminal at Folder.

Thank you Cat_7 for the command details!

Hi, According to the Host's Sys report under Catalina, the USB port on the older MacBook Pro says 'USB 3.0 Bus', and the MIDI interface's Speed is 'Up to 12 Mb/s' and 500mA power. The interface is connected to host without using a hub. I also experimented with the MIDI interface connected through an...

I pulled out my older MacBook Pro with USB-A ports and tried connecting the USB device directly to it.
But the behavior was all the same with OS9.2.2.

It worked once I removed the "-netdev" line from the command file. I guess its default values are not accepted. I also tried replacing this line with 'shared' and 'host' variations, but for those I get: -netdev vmnet-macos,id=vm,mode=host: Device 'vmnet-macos' could not be initialized Wher...

I tried the new build but I get this error:

qemu-system-ppc-vmnet: disk: drive with bus=0, unit=0 (index=0) exists

Also, shouldn't there be a line:
xattr -d com.apple.quarantine ./qemu-img

in the allow_qemu_to_run.command?

Please verify.

It's OK, it's not something I depend on (for now anyway), and besides I think it's cool enough that I came across and had the opportunity to dig into OS9@QEMU when I did.

I will hopefully wait for a future release that would resolve this issue, and thank you so much for raising that chance!

Thank you for your tips, Cat_7. I don't have convenient access to 10.3, although device driver is available. Nevertheless, my interested app is only compatible with OS8 and 9. Furthermore, the "Classic" environment under OSX does not support MIDI time management needed for playback (wherea...

Hi,

Sounds like we're getting warmer nontheless, thanks for your efforts!
I look forward to the day when my MIDI interface's activity indicator lamp ignites upon QEMU launch!

I tried the experimental build on Catalina (with sudo ./qemu.command under New Termial at Folder), but I get these errors: dyld: lazy symbol binding failed: Symbol not found: _pthread_jit_write_protect_np Referenced from: /Applications/Qemu-OSX-6.0pre-vmnet-05-02-2021/./qemu-system-ppc (which was bu...

pmj, Looks like we are on the same boat as far as getting the device recognized but unable to get it to do something. I am not familiar with Tascam units, but does it appear differently on a real OS9 machine? Perhaps the QEMU OMS thinks it is both a MIDI synth and an interface. Anyways, if you haven...

First, thank you Cat_7 for taking time to explain the filename dilemma. I understand and once experienced, I for one have no problems dealing with it. As for USB passthrough with my MIDI interface, The UM-880 USB MIDI interface has 2 driver modes: 1. "Original" (uses a device-specific driv...

Bravo Cat_7. Your Qemu-5.2-OSX-USB-Screamer-26-01-2021 build works for me! Now I can use QuickTime instruments with OMS. (there's a bit of a lag but can't complain!) If I were to be picky, "allow_qemu_to_run.command" mentionned in Readme should be fixed as "allow_qemu_to_run_screamer....

Dear Cat_7, Greetings, and my sincere respects and thanks to you for your contributions! Until a couple of days ago when I came across QEMU, I didn’t think I’d ever come so close to emulating my OS9 work environment on my MacBook Pro 16-inch running Catalina. I am confronting a situation somewhat si...
