MASCHINE as a Plug-in
If MASCHINE is loaded as a plugin in a host sequencer, the PLAY button in MASCHINE is disabled. All transport functions in MASCHINE are controlled by the sequencer in order to synchronize the playback.

If the PLAY button does not work when using MASCHINE 2 in standalone mode, a MIDI Sync Mode may be active. Open the MIDI tab in Preferences and choose Off from the dropdown menu next to Mode, to enable the PLAY button again.
MASCHINE 1 Software
If the PLAY button does not work when using MASCHINE 1 in standalone mode, the function Sync to External MIDI Clock in the File menu may be active. This is indicated by a dot or check in front of the menu entry. Deactivate the function by clicking the menu entry.
