constant survivor Posted June 18, 2021 Share Posted June 18, 2021 Hello again, today suddenly a strange problem appeared. As soon as I open up Logic, my MIDI controller (SFC-60) stops sending MIDI data. Before I open up Logic, it does transmit MIDI (checked via SNOIZE). I have some other controllers and they all are working fine. Its just the one. I played with some hardware MIDI configurations before the problem appeared but it's unlikely I think that this influenced the whole thing. I did not change any MIDI settings in Logic or on my MAC. Any suggestions? Best Hannes Quote Link to comment Share on other sites More sharing options...
des99 Posted June 18, 2021 Share Posted June 18, 2021 Check your Control Surfaces window to see if you have the correct controllers listed there are they are set to the correct ports. It's possible Logic thinks your controller is now a control surface and therefore blocks it's MIDI from the sequencer... Quote Link to comment Share on other sites More sharing options...
constant survivor Posted June 18, 2021 Author Share Posted June 18, 2021 Hi, thanks for response. I did a reinstall of Logic. Now it works fine again. Unfortunately I am the most impatient guy in the world so I could not check your solution... Quote Link to comment Share on other sites More sharing options...
David Nahmani Posted June 18, 2021 Share Posted June 18, 2021 Sounds a bit overkill but hey, if it's fixed... good for you! Thanks for letting us know. Quote Link to comment Share on other sites More sharing options...
constant survivor Posted June 18, 2021 Author Share Posted June 18, 2021 Hey, the problem still appears now and then. I don't really know which action leads to this behavior. After I unplug the controller and plug it in again it works fine until something happens... There are no controllers in the controller surface setup window shown.

David Nahmani Posted June 18, 2021 Share Posted June 18, 2021 When the issue occurs, choose Logic Pro > Control Surfaces > Bypass All Control Surfaces and see if the controller resumes working as expected? Quote Link to comment Share on other sites More sharing options...
constant survivor Posted June 18, 2021 Author Share Posted June 18, 2021 Yeah I tried that already but no success. Until now the controller did not do it again. do you have any further suggestions what the problem could be? Quote Link to comment Share on other sites More sharing options...
David Nahmani Posted June 18, 2021 Share Posted June 18, 2021 Try a different USB cable? Are you using a USB hub? Quote Link to comment Share on other sites More sharing options...
constant survivor Posted June 18, 2021 Author Share Posted June 18, 2021 tried another usb cable already. yes, I am using a hub (electron over-hub with power-supply). off-topic: please consider my other thread of today. have a follow-up question there unfortunately. Big thanks! Guess I gotta buy your book... Quote Link to comment Share on other sites More sharing options...
David Nahmani Posted June 18, 2021 Share Posted June 18, 2021 The controller is most likely underpowered by the hub. Try to connect it directly to your Mac (for troubleshooting purposes) and see if the issue goes away. Quote Link to comment Share on other sites More sharing options...
constant survivor Posted June 18, 2021 Author Share Posted June 18, 2021 sorry should have mentioned that: already tried to avoid the hub. problem still remained... for now the controller worked like it should for almost 3 hours of usage. maybe the problem won't occur again. thank you so far I guess we could leave it for now and I may come back if the issue occurs again.

I'm not sure if you've tried every combination of troubleshooting steps we've suggested? I would try without the hub, control surfaces bypassed, and different USB cables, all at the same time.

constant survivor Posted June 18, 2021 Author Share Posted June 18, 2021 yeah I will try again as soon as the problem occurs again. Quote Link to comment Share on other sites More sharing options...
David Nahmani Posted June 18, 2021 Share Posted June 18, 2021 You may also want to download Snoize's MIDI Monitor to help troubleshoot the issue. It will let you see if your Mac is receiving any MIDI data, taking Logic out of the loop. https://www.snoize.com/midimonitor/ Quote Link to comment Share on other sites More sharing options...
constant survivor Posted June 18, 2021 Author Share Posted June 18, 2021 I also already did that. when the problem occurs, The controller sends no MIDI data independently of Logic open or closed or whatever. But Logic definitely is the trigger. Quote Link to comment Share on other sites More sharing options...
enossified Posted June 18, 2021 Share Posted June 18, 2021 The SFC-60 is an odd duck as controllers go. It's designed to only control software instruments, the TAL Uno in particular. If you are using it with that plugin, the manual states: In the menu of the plugin, you will need to turn on the option “SFC 60 MIDI controller”. With that option on, the plugin will now send MIDI messages to the controller when presets are changed and instances are switched. The controller will ingest that data and update all the LED-based switches on its interfaces. It wouldn't surprise me if the controller firmware gets confused when it recieves MIDI messages other than those sent by the plugin. Have you contacted the manufacturer about this problem yet?

constant survivor Posted June 18, 2021 Author Share Posted June 18, 2021 yes I did that but after I did, the controller started working again. so I wrote to him that everything's fine. I have to observe the problem a little longer I guess to be sure about what's going on. but as you said it actually "feels" like the controller is getting some wrong information at a certain moment and then refuses to send data. I'll keep you updated when there are news. Quote Link to comment Share on other sites More sharing options...
des99 Posted June 18, 2021 Share Posted June 18, 2021 (edited) This rings a bell of someone's semi-DIY controller here recently that was running some kind of open source firmware for MIDI control. When Logic ran, it sent some data to the device (a query for connected controllers, generally), which then completely killed the controller's MIDI output. It turned out the firmware for the device wasn't expecting to receive MIDI bytes, and then hung when it did so. A little extra handler in the MIDI routines to correctly handle incoming data gracefully and the controller then worked from that point. The problem as described seems similar. I'm sure a few searches will turn up the thread for the info, and perhaps forward this to the developer of that controller if it looks a likely possibility. It wouldn't surprise me if the controller firmware gets confused when it recieves MIDI messages other than those sent by the plugin. Yes, exactly.

I also think that it is some MIDI message "confusing" the controller. I forwarded this thread the developer who, by the way, already replied that some other user has the same issue. I have two other controllers of the same manufacturer and they work without problems so far. Quote Link to comment Share on other sites More sharing options...
enossified Posted June 18, 2021 Share Posted June 18, 2021 Definitely set up a MIDI Monitor and see what messages are coming out of Logic. Then pass that data along to the manufacturer. Quote Link to comment Share on other sites More sharing options...

Logic can not affect what your controller is sending to your Mac. It can affect only how it interprets what it’s receiving. If Snoize doesn’t show anything then Logic isn’t receiving anything.

What do you mean? After the problem occurs, the controller is not sending MIDI to the Mac at all anymore (monitored with SNOIZE). Definitely set up a MIDI Monitor and see what messages are coming out of Logic. Then pass that data along to the manufacturer. good suggestion!

enossified Posted June 19, 2021 Share Posted June 19, 2021 I noticed that the other SoundForce controllers don't offer the feedback from the plugin feature like the one for the Uno. My guess is they work fine with Logic because they ignore incoming MIDI. Good luck! Quote Link to comment Share on other sites More sharing options...
