Ableton has updated Live to v7.0.12.

Improvements:

• MIDI surface controller support for the Alesis Master Control.
• MIDI controller support for Vestax VCM 600.

Bug fixes:

• Operator's voice stealing would not work properly.
• Under certain conditions an empty MIDI effect Rack could lead to audio drop-outs.
• The 'Rename' command for an Impulse slot would not be available via the context menu.
• A copied or moved Reverb would not properly show the correct curve with Diffusion Network enabled.
• After installing content packages, a dialog could show a message about a failed installation although the installation was successful.
• A copied or moved Tension instrument would not show the correct filter curve.
• Dragging a particular chain from a Drum Rack into 'empty' Arranger space could crash Live.
• On Windows Vista, resizing the main window would heavily flicker if AERO was enabled.
• On Windows Vista, locking the computer or coming back from a screen saver would temporarily disable AERO.
• Moving a clip in a track with an External Instrument and routed to a multi-timbral plug-in could crash Live.
• Moving zones in the the Sampler could lead to hard disk dropouts.
• Live's search index would not properly handle version 2.3 ID3 tags.
• Dragging in a clip containing an Audio Unit plug-in could cause a message box to appear, canceling the drag.
• Some memory leaks could appear under Vista when resizing windows.
• Tighter MIDI timing when looping in the Arranger.
• Files would incorrectly be dated as "Yesterday" during a few hours around midnight.
• The macro settings of a rack containing certain third party plug-ins would not properly restored when loading the rack.
• Having multiple automation lanes on an audio track and removing one lane would not properly display the audio waveform on the remaining lanes.
• Doing the the Capture and Insert Scene command could create a memory leak.
• When running as MIDI clock slave, Live would only display a rounded to the nearest integer tempo.
• On Mac OS X, the functionality to ask the AU plug-in for its supported formats would not work properly.
• If Live would run as ReWire slave but would not get called from the ReWire master for some time, a message box would appear to inform about that problem. This message box again could lead to a crash of Live and the ReWire master. Now, the the message about the inactive ReWire master is displayed on the status bar.
• Sending a MIDI program change message from an external MIDI source into Live would lead to a crash.
• Depending on the structure of the current Live set, arming a track could be extremely slow.
• Unlock offline would not work properly.
