MIDI support in Sierra

Hey, just wanted to update here since I solved this problem for Roland A500S, if you take a look at the side where all the connectors are there are also two switches (luckily). One of them is for power, the other one is for "Advanced Driver". I solved this problem by setting it to OFF on the power switch then flipping it to OFF for the Advanced Driver and then back to USB for the power. Then it just started working 🙂

I'm having the same problem. Once I upgraded to OS X Sierra, the iMac no longer recognizes my Edirol PCR-50 MIDI controller (keyboard), even with the latest drivers installed. It can't even tell when it's connected via USB.

I'm extremely outraged! Have you found a solution?

The same thing's happened to me too, since upgrading to Sierra!

The IAC driver in the Midi studio is greyed out for some reason!

If Apple are aware of the problem then they're certainly taking their time sorting out a midi driver that works in Sierra!

I just installed Sierra update Ver 10.12.4 (16E195) and the issue still hasn't been dealt with!

I wish I'd seen this thread before I upgraded to Sierra. I use an Edirol PCR-800 for live work with Mainstage and my MacBook now won't recognise it. I've just found this on the Roland support site (https://www.rolandus.com/support/knowledge_base/205113475), but if it doesn't work I'm going to dump the Sierra update.

Just wanted to put this out there.

PCR M-30 Midi controller keyboard (PCRM30 PCR-M30).

I got this to work with Sierra 10.12.5 and Logic Pro 10.3.1 by switching to the GENERIC DRIVER on the keyboard itself. The process is described in the manual, but just in case anyone doesn't have it :

PRESS EDIT button

Press SYS key

Press '6' key

Press 'ENTER' button

Use the 'dec' and 'inc' buttons to toggle between ORG and GEN drivers . You want GEN.

Press ENTER button.

Switch off and on again.

DONE!

Same problem!! I upgraded to Sierra. Now my Miditech Midiface (little device that connect midi to usb) does not work!!

On an older macbook it works properly.

Please, Apple Support... Anyone is listening?? Update with solution is needed!! 😠

I also have this problem and I'm surprised there is no outrage on the boards.

My MIDI function is not working on Sierra - and neither am I - 😠

Roland A-88 here. Luckily I have a MacBook on El Capitan that I can use instead.

PS. Roland has its Sierra Compatibility page up. Appears to be a partial list. I expect they will add information over time.

I have same issue, but with a generic midi adaptor that worked perfectly till now. Opening the AUDIO MIDI Setup/ MIDI Studio, when i click on re-explore MIDI, it appears, and the number of entries change to plus 2, but doesn't work and don't let me check the device enabled. If again I re-explore MIDI, the number of entries change to minus 2

So it seems the only solution will be downgrade to el capitan and wait for better times. BTW siri on my computer has proven to be pretty useless, so no worries about downgrading (except that is time consuming)

As soon as I upgraded to Siena all my midi devices have horrible latency. Everything worked great before. MacBook early 2015.

A partial compatibility list is not good enough for those of us who invested in Apple & Roland products.

As a professional user, I am losing time and $$ - and how about you?

This driver didn't work at all ~~~~~ my RD-700GX is a professional keyboard. Where is the professional support?

I had to restore back to the old os and everything worked again. It took about 3 hours to restore and luckily I backed up before I upgraded as it would have been a disaster. On another site some recommended to install the new os on a separate partition so you can test it with your gig setup and it will not mess up what you have in the old os. I feel it is something with the os core midi rather than a third party issue as everything was screwed up, not just one software.
