Technical Support

Blake, I turned it on and it is available in Logic and in EMU - I see it. I just don't have "Midi out port" in Logic like you have. Added pictures to show what I've said.

BTW guys, I've got a new alpha, devs said new protection not to damage EMU applied. You may want to use it - go ahead: 23.02.15.3. 

Hi Andre, 

IAC Bus Driver is something that has to be turned on in the computer settings. I don't remember the exact steps, but there are videos on youtube outlining what to do if you search "IAC Bus Driver Logic".

Guys thank you all for the help, you made great effort to figure out the issue. Especially Blake. As for me I fall back from you and like Robbie don't see Midi out port to make it IAC driver bus 1. However my Logic is 10.7.5. Will try tomorrow to make video, may be you will be able to help me to pair Logic midi with EMU. As I am lusting to reproduce the issue you faced.

Andrei - That's also probably some good information for others, that this feature that fixes the issue is a relatively new addition to Logic. Versions from before late 2021 cannot utilize this fix. 

Thanks Christopher :D

Robbie - This was added in Logic 10.7 which came out in late 2021. Check to see what version you're running as it won't be there for any version prior to 10.7. 

Everyone - after some additional testing, I believe I have figured out what exactly fixed the issue! I tried to replicate what I was doing in a fresh session. At first, I had the same issue with crashing EMU. Here's what you have to do in the official release of EMU to solve the problem. On your external midi channels you have to select OFF for the Midi port in setting. Having this set to ALL, which is the default, will crash EMU pretty much every single time you send midi out. Setting it to off resolves the issue and EMU will act as expected. Based on the info that Andrei has provided, I'm assuming this set to all is creating some kind of midi feedback loop that is overwhelming EMU with 600k requests per second as Andrei said he saw in the logs. 

Andrei - I have uploaded a shorter video just showing what fixes the issue, see below. I am going to opt to stay on the current official release of EMU for now as it is working and stable. As much as I appreciate the work that went into creating all of these alpha versions, and I don't think we would have figured this out without them, I believe the fix is just the one I have outlined above, and no actual change in EMU is needed to resolve the issue. I might suggest having this step included in some instructions somewhere for Logic users as I'm sure many others have had a similar issue since the default external midi setting in Logic is what is causing the crashes. https://www.dropbox.com/s/hp3256f4fk7hzv5/ISSUE%20RESOLVED.MOV?dl=0

CHRIS AND ROBBIE, 

I HAVE UPLOADED A VIDEO TO THE DROPBOX LINK THAT I SENT BEFORE SHOWING EVERYTHING I HAVE GOING ON IN LOGIC AND EMU. CHECK THERE. IT WILL PROBABLY TAKE A LITTLE BIT TO UPLOAD, SO IF YOU DON'T SEE IT, CHECK BACK IN A LITTLE BIT. Sorry for caps locks, I started typing without looking at the screen. 

Hi Chris, and Robbie,

In a little bit, I'll take a full video detailing exactly what I'm doing, and all of the settings I've got going on and post it here.
