General

• More tolerant error handling when loading custom fonts.
• Selected installer language was not used when upgrading from 3.0, this is now fixed.
• We have improved the error handling when copying Remote maps and codecs during start up.
• All sample players (NN-XT, NN-19, Dr Rex and Redrum) - High Quality Interpolation is now enabled by default.
• Improved handling of mono/stereo connections while auto-routing.
• Dragging devices to the rack from the tool window only worked with the top-most window, now it works with any window.
• More robust error handling during startup, avoiding certain timing problems in Windows.

Sequencer

• Automation type for Dr Rex transpose parameter was continuous - changed this to stepped.
• In certain situations Command-A did not work properly on Mac OS X.
• Notes with same Start or End position could change the play/stop order randomly. This could only be noticed while playing chords on a monophonic device. This is now fixed.
• Fixed note trig queuing for extremely short notes. This was causing phased effects when doubling clips exactly on two layers.
• "Reset automation override" could default to wrong value.
• Pressing Stop the second time moves the song position locator to previous start position, it could sometime move to song start if the locator had been repositioned during playback.
• MIDI import of file with redundant note information is now filtered.
• Uncombining a Combinator deleted the Combinator's sequencer track. This is now fixed.
• Reason could take a long time to respond when entering extreme numbers in position editors.
• Overriding parameter automation by loading a patch did not always indicate automation override. Now fixed.

Improved workflow in sequencer

• If a clip is selected in Arrange mode and you switch to Edit mode, the clip is automatically opened for editing. This only happens if the clip is on the current track.
• You can press [Esc] to close an open clip in Edit mode. If the clip was opened from Arrange mode, this will automatically switch the sequencer back to Arrange mode.
• Only one single clip is created in loop record mode. Before, a new clip was created for every new loop.
• Changed Zoom behavior: The program now zooms on the song position locator if it's in view. If not, it zooms towards the left edge of the current view.
• Drag and drop now also works in left-handed mouse configurations.
• Text-entry of a tempo with a decimal in the transport panel or when editing the static value was counter-intuitive: Typing something like '120.5' or '120.05' delivered 120.005. This is now fixed.
• Added label to velocity and pattern lanes.

Remote

Added Remote support for:

• Akai MPD24
• Akai MPD32
• Akai MPK49
• Edirol PCR-300/500/800
• Frontier Design Group Alpha Track
• Line 6 KB37
• M-audio ProjectMix I/O
• M-audio Axiom 25/49/61
• M-audio Oxygen 8 v2
• Fixed a performance problem with the Remote Override "learn" feature.

Browser

• Performance problem when having many ReFills installed.
• Reason could crash when saving if there was more than 300 ReFills installed -fixed.
• Better error handling while file searching in browser.
• Broken search for missing sounds in songs created with OS hide extensions enabled - fixed.
• Changed wording of memory usage in patch browser to avoid confusion.
• Saving patches in Reason version 4 and ReFill packer had a backward compatibility issue - fixed.
• Sometime the static value was not imported correctly when loading old songs - fixed.
• If an opened patch or sample had been moved or deleted while Reason was running this could prevent the user from saving the song - fixed.
• Reason could in certain cases unexpectedly quit when saving on Mac OS X - fixed.

Combinator

• If many devices in a Combinator were programmed to switch "Receive notes" on/off in the Combinator's programmer, some devices responded slower than other devices. This is now fixed.

Malström

• Increased the buffer size of Malström's Comb filter, this fixed problems with high sample rates.

RPG-8

• Fixed velocity CV and knob/automation lag when in random mode.
• Fixed broken velocity change of tied single note when in ON-mode.
• "Render Arpeggio To Track" was broken when pattern automation lane was enabled.
• New shortcuts:
  Shift pattern right: Ctrl + J (Win) or Cmd + J (Mac)
  Shift pattern left: Ctrl + K (Win) or Cmd + K (Mac)
  Random sequencer pattern: Ctrl +R (Win) or Cmd + R (Mac)
  Alter Pattern: Ctrl + T (Win) or Cmd + T (Mac)

Thor

• Thor's sequencer have new shortcuts:
  Shift sequencer pattern right: Ctrl + J (Win) or Cmd + J (Mac)
  Shift sequencer pattern left: Ctrl + K (Win) or Cmd + K (Mac)
  Randomize pattern: Ctrl +R (Win) or Cmd + R (Mac)

Audio Card

• Reason could go silent if the sample rate was changed in Windows Vista or on an aggregated audio card driver in Mac OS X. This is now fixed.

ReWire

• Fixed a ReWire problem with FL Studio, making it more robust.
• Made Ableton Live and Reason ReWire connection more robust.
