Ableton has updated Live to v4.0.4.

Bug fixes:

• Select clip crash - Under special circumstances Live would crash when an audio clip was selected with the mouse.
• Automatic creation of audio tracks - Live would be crashed when dragging an audio file into the "empty" space in the arranger
• Play scene using KEY or MIDI Remote - Assuming you have so much scenes that the vertical scroller appears. If you had then fired a "hided" scene using KEY or MIDI Remote, the scene would not be selected.
• Hanging Notes - Sometimes it was possible to create hanging notes when switching the OVR button.
• Impulse Instrument - Under special circumstances there were MIDI drop outs when many voices were requested at nearly the same time.
• VST preset - Some VST plug-ins are not VST conform in their parameter range like GMedia M-Tron, IK Multimedia Sampletank 1LE. When loading a song with such VSTs Live would correct the parameter range.

Improvements:

• LinPlug RM IV - Better performance with LinPlug RM IV when triggering a pad in the GUI
• Improvement: MIDI files with invalid data - Better support for MIDI files with invalid data. Now it is possible to open such files by correcting the data.
