Ableton has updated Live to v4.1.3.

Changes:
.Bugfix: Audio effects in MIDI track – Live would behave strange when loading a document with two or more audio effect device in a MIDI track but no instrument.
.Bugfix: MIDI editor velocity selection – When selecting MIDI velocities using a selection frame all MIDI velocities along the horizontal size of the selection frame would be selected, also if they are not inside the selection frame.
.Bugfix: Too many automatable parameters – Under special circumstances Live would deny to open large Live Sets containing too many automatable parameters because an internal limitation. This limitation value is now increased.
.Bugfix: Potential crash with MIDI or Audio devices – To detect if a MIDI or Audio device caused a crash Live creates and files to mark such a crashed device. If it is not possible to remove such a file Live would crash.
.Bugfix [WIN]: Key handling after VST close – For some VSTs (like z3ta+) Live would not get computer keyboard input after closing the VST. This problem is fixed but Ableton had to change the way the VST is closed so it is important to get feedback about related problems with other VSTs.
