This version fixes the following issues:

Viewing the sequencer area by pressing F7 would always reset keyboard focus to the track list, with confusing results. Now the keyboard focus setting is properly remembered.
If you changed settings in the Tool window when there was no open song document, the program could crash.
The output of the RV-7 "Large Hall" algorithm was in mono.
Copy command (Copy to clipboard) could cause an "Unknown Exception" error message.
A few remote codecs (including Behringer BCR/BCF, Korg Kontrol49 and mikroKontrol) were not properly replaced when Reason 6 was installed over an existing Reason 5 installation, which made them stop working under Windows 64. Now they are replaced by the new version at installation.
Some audio hardware models (that worked fine in Record) stopped working with Reason 6 under Mac OS X.
If Reason received MIDI Clock while in ReWire mode, the program could crash.
With some HID devices (e.g. Tablet input devices of certain brands) connected, Reason couldn't launch properly.
Bounce Mixer Channels would cause Reason to hang if the program was in MIDI Clock Sync mode.
Using the Speaker tool repeatedly in the audio editor could occasionally make the program hang.
When the scratch disk became full, Reason 6 could crash.
Old non-unicode keyboard layouts (Mac only) could cause Reason 32-bit to crash at startup
On a Mac with a two-monitor setup and the SecondBar tool running, some actions could cause Reason to crash.
Loading samples, opening and saving songs could take a very long time in some situations.
General performance has been improved in many areas.
The Novation Automap Control remotemap has been updated
Remote support for Teenage Engineering OP-1 has been added.

In rare cases, the Save and Optimize could destroy the song file. This would happen if the operating system reported a problem to Reason at a bad (very specific) moment during save and optimize.
Using the context menu on text fields in the tool window that could cause a crash.
If some actions were performed in the browser while the name of a Favorite was being edited, this could cause a crash.
Tempo map information embedded in audio files within ReFills couldn't be read properly. Now it can.
The program now includes Line 6 TWXY 5.26.0. This allows access to computer authorized Line 6 models in Reason and makes the program compatible with Pod Farm 2.5.
Zooming with the scroll wheel has been made smoother.
The vertical navigator in the mixer did not reappear correctly (after being automatically hidden).
The previous version accidentally included a beta version of ReWire. Now, the deployment version is included instead.
Removed some misplaced text from the context menu in mixer (when running the program in French).

- More sounds
The included Factory Sound Bank has been expanded with thousands of new patches and loops for Reason's instruments, and hundreds of patches for the new Pulveriser, The Echo and Alligator effects. Finding your sound has never been easier.

* The handling of bad sound drivers has been improved, lessening the risk of a crash due to faulty drivers.
* Added Remote support for M-Audio Oxygen 88.
* Added localized help and documentation in German, Japanese and French. Note: The localized help and documentation files are automatically included when Reason or Record are installed from the DVD. When downloading Reason or Record, you need to download and install localized help and documentation separately.
* During certain circumstances, if a MIDI control surface was locked to a device and the user deleted any device from that song, the program could crash. This would happen if there was another song open and that song was playing back in the background.
* The "Arpeggio Notes to Track" function on the RPG-8 could cause the program to crash if some of the RPG-8 parameters had been automated.
* Saving a patch could in rare cases cause the program to crash. This happened if the user loaded a patch from a folder containing a huge number of patches, then moved the patch file to another folder and finally attempted to resave the patch by Alt-clicking the Save Patch button on the device.
* In some cases, after copying and pasting a sample-based device from one song to another, the pasted device could refer to the wrong samples if the samples were self-contained.
* Cable drawing has been slightly improved.
* Thor's step sequencer in random mode triggered two voices. This could happen when the "Step" run mode was selected and the direction was set to "Random".
* The program will occasionally check the available hard disk space. On some systems, these checks could make the user interface temporarily unresponsive.
* Duplicating devices a large number of times could cause a graphical bug in the rack.
* A number of localized (translated) text strings were cut off.
* Voice handling for the NN-XT has been optimized slightly.
* Dr. OctoRex slice numbers were not shown correctly in Edit mode when using the application in German.
* If a song used SoundFonts under Windows Vista or Windows 7, the program could store the wrong path to the referenced samples. As a result, there would be missing sounds next time the song was opened.
* Switching from MIDI sync to internal sync could result in an "Unknown Exception" alert.
* The program could become very unresponsive when working with songs with a large number of self-contained samples.
* Songs or combi patches could load with incorrect settings. This happened if a Combi rotary or button had been programmed to control a certain device parameter, and this parameter had been changed "manually" so that its state conflicted with the Combi rotary/button. After saving and loading, the setting of the device parameter was reset to match the Combi settings.
* When stopping after recording in ReWire mode, the program could freeze for a few seconds.
* Updated some Japanese translations.
* The program could assert when changing to virtual MIDI input settings.
* Kong's Nurse Rex in Slice Trig mode within a Mute Group would not mute the voice when another pad was triggered.
* A crash could be caused by dragging one or more half width devices and hovering over a Disk Channel device that doesn't show inserts.
* The function of bouncing several audio clips to new samples or to a new recording could take longer than expected.
* The remote override mode was not completely blocked while the program tried to quit.
* Muted audio clips in Blocks while adjusting the Block Clip offset could look a bit peculiar.
* Sample Editor now handles samples with a sampling frequency below 8000 HZ correctly.
* Names of Mix Channels could become blank in certain cases.
* Bug in the Mix/Disk-channel, which could occur whenever a device was added or removed in the combi of a channel device (insert effects). This bug might show itself by some short clicking sound, artifact or short freeze when adding or removing devices in a channel device. The Combinator was not affected, and also not the master section.
* There was a bug when the user tried to move the notes that were being recorded either by scaling the tempo in the tool window or nudging them with Ctrl-left/right.
* Handling of ReGrooved blocks has been improved.
* NN-Nano now uses High Quality Interpolation when pitching samples.
* Converting pattern automation to notes disregarded pattern offsets incorrectly.
* Automation of aftertouch, expression and breath are now smoothed in Thor.

- Kong Drum Designer
Analog synthesis, physical modeling, sampling, REX loops, support sound generators, effects, flexible routing, multiple hit types and more. The Kong Drum Designer is not your regular drum module. It's the drum module focused on letting you get exactly that drum sound you're after. Kong has 16 pads and 16 drums. Build your drum sounds based on any of the nine different drum modules. Flavor the sound with 11 support generators and effects. Program automation, create alternating groups and let Reason's powerful sequencer control the beat. Reason 5 ships with a sound bank with a generous supply of kits for Kong across a wide variety of styles.

- Live Sampling
Remember the time when samples were something you sampled and not loaded from your hard drive? When a sampler was a machine that could record samples, not just play them back. As samplers became software instead of machines, they came to rely on external sample editing software for recording and editing the samples and the art of spur-of-the-moment creative sampling was pretty much lost. Now we are bringing it back to Reason 5 with its live sampling input. All sample players in Reason are now samplers. Just hook up a sound source to the rack's sampling input and you are ready to start sampling. Use a mic, a turntable, an instrument or the entire Reason mix. Sampling in Reason is simple and straightforward. Hit the sample button and Reason starts sampling. Reason will detect the sample start automatically. You can sample when Reason is running too if you like - no need to stop the music. If needed, bring up the built-in sample editor to set start and end points, loop points and more. This is possible for all loaded samples by the way - not only the ones you have sampled.
As always, Reason lets you focus on music making - and sampling in this case. All samples are neatly stored in our song file and accessible in the new samples pane in the tool window. Here you can easily see what samples are loaded into what machine and delete and export samples as you wish.
Live sampling together with pitch detection of root key and automatic zone mapping makes it dead easy to sample an instrument and map the samples across the keyboard. This way you'll create your own multi-sampled instruments for NN-XT and NN-19 in an instant.

- Neptune
Getting a vocal performance right means so much more than hitting the right notes at the right time. Sometimes you get that almost perfect performance with perfect feel and presence, but the singer might have missed a few notes. That's when Neptune can save the day. Neptune is an advanced pitch adjuster, audio transposer and voice synth for Record 1.5.

As a pitch adjuster, Neptune will fine tune the pitch of an audio track to help getting your vocal performances just right. Neptune will fix the flat notes with an unbelievable audio quality . You can select a root key and a scale that you want the adjuster to use, or create a scale that fits your song. And, yes. By cranking the pitch adjustment settings to the max, you can get that effect sound too.

Neptune is also a natural sounding audio transposer. This is a great help if you ever needed to change the key of a song that's already been recorded.

Perhaps the most creative-sparking function in Neptune is the voice synth. Play your MIDI keyboard and Neptune will create new harmonies from your vocal tracks in real time, or use it without the original voice to completely change the melody of the song. Endless creative options!


- Blocks
Many musicians tend to think of music in terms like intro, verse, chorus, breakdown, buildup and so on. With the new Blocks mode in Reason 5 and Record 1.5, your sequencer does too. Blocks lets you sequence your songs using a more pattern-based approach, with the segments of your song as individual building blocks to be laid out in your arrangement.
Start by creating the discrete parts of your song in blocks mode. When you are ready to start building your song, just switch back to song mode and draw in what blocks should play in the dedicated pattern lane. Use one block for the verse and one for the chorus — or build your song around a single 8-bar loop.
Blocks provide a very fast way of creating a musical structure for your song. But the options don't end there. With the basic arrangement laid out, you can see the contents of the blocks and create variations and mute individual parts, or add further musical elements in song mode.
A typical use for Blocks is to create your backing track in blocks and then use the song mode sequencer to record vocals or instrumental performances. For music based around a single looped section, one repeated block with automation and mutes of individual tracks added in song mode makes arranging a breeze.
You never have to commit to using either mode - you are free to move back and forth between Blocks and Song mode, and any changes you make in your Blocks will instantly be manifested in all instances of that Block. Need some tambourine on that chorus? Add it, and there will be tambourine whenever the chorus block is playing.

- upgraded Dr. Octo Rex
The upgraded Dr. Octo Rex loop player loads eight REX loops into one player and lets you switch between them on the fly. This makes arranging a breeze - load the drum loops into one player, the guitars into another and use the sequencer to select what loop to play in a pattern-like fashion.
With eight loops to switch between, the new loop player also comes ready for the experimental minded. Set the player to retrig the loops on the beat, on the bar or on the 16th note. Or program the loops manually like in the original rex player.
For each of the eight loops, the new rex player also comes with an expanded set of per-slice settings. Set pan, pitch, filter frequency and level, reverse slices, use multiple outputs, create alternating groups of slices and much more.

- Automatic Self-Contain of Samples (incl from ReFills)
Make your songs self-contained by embedding samples and even ReFill sounds in your file. Reason 5's self-contained song format makes collaborating with your friends a breeze. Even breezier than before actually.

- Record Notes on Multiple Tracks
Reason 5 and Record 1.5 lets you use multiple MIDI keyboards, pads, and controllers for playing and recording your instruments. Lock a 16-pad controller to a Kong, and use a keyboard to play your synths. Or use two keyboards on stage for controlling different Reason instruments.

- Scale Clips by Resizing
By pressing the alt or option key, Record 1.5 lets you timestretch individual clips. Now you can stretch loops to match your song's tempo, or expand samples to eight times the length for completely new sounds.

- Mute Tool
The new Mute tool lets you click to mute and unmute clips. Use it to mute sections, or create variations in your Blocks.

- Set and move loop functions
Select a clip and press L to immediately set the loop points to the selection. Use the new Remote parameters for real-time control of the loop points from your MIDI controller.

- Tap Tempo
New in the transport panel is the Tap Tempo button.

- Improved key commands for laptop use
Reason 5 and Record 1.5 works even better on your laptop – or any keyboard missing a numeric pad. The new key commands lets you control play, loop, record and more from your keyboard.

- Hierarchical menus in Combinator programmer
A sound designer favorite, the Combinator's programmer window is now even easier to use with hierarchical menus for fast patching.

- Additional CV inputs on Combinator
The Combinator in Reason 5 is expanded with new CV inputs on the back. The four new CV inputs can be used to control any parameter on the contained devices, providing even more options and possibilities for sound designers.

- Updated Help system (incl Help on Mac)
Reason 5 and Record 1.5 comes with a new and better built-in help system, on both Mac and Windows.

- Normalize and reverse audio clips
In Record 1.5 you can normalize and reverse your recorded audio clips.

- Bounce clip to sample
When using Reason & Record, you can now bounce audio recordings to samples, so you can use them in Reason devices such as Kong, Redrum, NN-XT and NN-19.

- Reason 5 updates
In Reason 5 there are tons of changes to bring Reason up to speed with Record. These changes include advanced multi core support, improved cable management in the rack, faster sample loading, on-screen piano keyboard, sequencer usability improvements and much much more.

A maintenance update that resolves a few minor issues and, as a response to user feedback received for Reason version 4, brings some small workflow changing alterations.

new patches
Tool Window
Combinator & NN-XT updates

This is the new Intel Mac compatible version that also packs some serious ReWire performance gains for owners of older macs.

These are the issues that were fixed in the 3.0.4 update:

- MIDI import
The MIDI import functionality in Reason 2.5 accepted some MIDI file data that the Reason sequencer could not handle. This could for example be bad controller data outside the sequencer timeline. Saving this bad data to a song made that song unloadable, causing a "Bad Format" alert. In Reason 3.0 we made MIDI import stricter and also changed song loading so that bad data was skipped instead of showing the alert. Unfortunately there were some problems with this handling, which we have now taken care of.

- Loading old songs
Some songs produced in Reason 2.5 could not be loaded in Reason 3.0 or 3.0.3. We have addressed some issues regarding NNXT patch data created by some patch conversion utilities, where Reason 3.0 is stricter than Reason 2.5 was.

- Cross-browsing
There were some situations with cross-browsing (replacing a device by loading a patch of a different device type) that caused "Unknown Exception" alerts in Reason 3.0 and 3.0.3. This has now been fixed.

- Combined note handling
Sending overlapping notes from the sequencer to a Combinator that contained a Malström in Legato mode could cause hanging notes in Reason 3.0 and 3.0.3. For example, drawing two C4 notes where the second note starts before the first ends, and setting the track target to the Combinator produced different results than setting the track target to the Malström. This has now been fixed.

- Missing icons in Mac OS X 10.4 (Tiger)
After installing Reason 3.0.3 in Mac OS X 10.4 refills icons could change appearance and turn blank. Also all wave and aiff files were wrongly associated to Reason. Both of these issues were a result of new handling of file types in Mac OS X 10.4. This has now been fixed.

Additions in Reason 3.0.3 :
Added Remote support for the Frontier Design Group TranzPort wireless controller
Added Remote support for the M-Audio Ozonic
Track mute and solo for selected track now controllable from Remote

Fixes in Reason 3.0.3
- Keyboard Control
There was a problem with Keyboard Control in 3.0 that could get Reason to crash, now fixed. Therefore, loading songs produced in 3.0 in version 3.0.3 will clear any Keyboard Control mappings.

- Pattern Change Automation
There were some issues with automating pattern changes in 3.0 that made some songs play back differently than in Reason 2.5. Since we now have fixed this, some songs produced in Reason 3.0 will now play back differently in 3.0.3.

- Triggering the RV7000 Gate
The function that triggers the RV7000 Gate via MIDI didn't work at all.

- "Bad Format" when opening NN-XT patches or songs
If an NN-XT patch references samples with names (or folder names) that include exotic characters, the patch may not load properly in Reason 3.0. This is fixed in 3.0.3.

- Remote Override of Dr.REX Preview
Remote Override mappings for the Dr.REX Preview button were lost when opening a song. This is fixed in 3.0.3.

- Replace mode recording
Recording in Replace mode played back the notes being overwritten. This is now fixed. Note that replace recording is only activated for automation data after the automated controller is modified.

- Loud noise when playing back in Loop mode
When playing back an NN-XT patch with Loop activated on the transport bar, the NN-XT could in Reason 3.0 produce a loud transient noise at the loop end position. Fixed.

- Automation of Combinator controls
When you automated a Combinator control (button or rotary) and played back the automation in Reason 3.0, there was a tiny delay before the Combinator passed on the information to the devices within it. Fixed.

- Pattern device Resolution can no longer be remoted
The Resolution parameter on the Redrum and Matrix could not be controlled remotely. Fixed.

- Hard to edit sequencer data during playback
In Reason 2.5, "Follow Song" was temporarily disabled when you pressed the mouse button. This feature did not work properly in Reason 3.0, but is now fixed.

- Program continues to draw or move data just after I release the mouse button
The program was slow to react when the user released the mouse button. This has been addressed and is much better in 3.0.3. This can unfortunately still be noticeable on lower performing computers.

- Remote issues
For some users with M-Audio Radium keyboards, the Remote implementation doesn't work properly in Reason 3.0. It turns out there are two different Radium models, with different settings in factory preset 1 (just like Oxygen 8). Reason 3.0.3 includes support for both the old and the new Radium models.

- Performance problems
Several performance and CPU usage issues with Reason 3.0 have been found. There were for example problems with certain settings on the MClass Equalizer, the DLL-1 delay and the Subtractor's noise generator, which could all cause occasional high loads on the CPU. All these issues and many more have been isolated and fixed in 3.0.3.

- Overall performance optimizations
All components of the audio engine and the user interface have gone through extensive profiling which has significantly increased performance of Reason 3.0.3 compared to 3.0.
We have also been able to optimize sample loading performance so that loading times for samples have decreased further in Reason 3.0.3.
