Have successfully installed CuBase LE5 onto an ASUS laptop.
When importing a MIDI file (which has been successfully played on WIndows Media Player), the MIDI commands can be seen in the Project Window, music in the editor, but nothing can be heard on playback.
The metronome can be heard, audio can be recorded and heard on playback.
In Device Setup VST Audio System 3 choices are available:
ASIO DirectX Full Duplex Driver
Generic Low Latency ASIO Driver
Audio Playback and hearing of the metronome tick only occurs in the ASIO4ALL v2.
