We are seeing this randomly, so the more detail you can provide the better. It also seems to be isolated on OSX systems, correct?
- Did you update to latest driver & controller editor from the driver section?. There is a 1.4.5 update out.
- Did you download the update for the ableton template via service center?.
- Can you also reproduce the problem when ONLY having maschine connected directly to a USB port and not to a hub?. With Various cables?.
- Please disconnect any devices on the physical midi in/outputs of maschine and retry.
If any of you that are suffering this problem have xcode installed, and know how to produce a shark log, please send me a PM since this would be a great help in tracking the issue on your systems.
