Hey there,
we are sorry you are having this issue but it seems like it is a communication issue between the two devices in tempo, the Aeros is receiving what it believes to be a much faster tempo than what it is meant to be. The Aeros must read MIDI Sync ON to work correctly when receiving clock.
It’s very interesting you say it is a new issue
Because we do not have a Maschine on hand to test this, we cannot say exactly what is happening, but I would be interested to know (if you still have the device) if you have better behavior on version 5.0.0 which is now in beta.
Thanks for reporting, we will look into this more as we have more time to ensure 3rd party devices are acting as expected.
