Stronger, swifter, and smoother to work with, Reason 4 music production software will alter the way you create your music. It comes in the familiar shape of a classic studio rack, packed with all the gear you could possibly need: samplers, analog synths, graintable synth, vocoder, mixer, step-time drum machine, arpeggiator, compressors, EQ, and effects. A realtime multitrack sequencer provides full control over every detail, letting you create and edit your music quickly and intuitively. Reason 4.0 also has a massive sound bank full of sounds, loops, and patches for all possible styles of music. The devices and features added to Reason 4 software will not only inspire you to produce great tracks, they will provide you with new ways of doing so.


Dedicated to turning your ideas into great music, Reason 4's sequencer is swifter, stronger, and more intuitive than ever with a whole new look, tons of fresh features and a completely new way of handling sequencer data. The key word here is workflow. A sequencer device or instrument now gets its own dedicated track, with separate lanes for note, performance, and automation data, opting for a better overview and less clutter. All sequencer data”notes, automation, the works”is now housed in clips, musical building blocks that can be opened, sliced, or moved. When a clip is moved to a new location, all its internal data follows right along with it, ending up exactly where you intended for safe, speedy sequencing. The Tool window is an ever-present floating window that provides lightning fast access to those detailed editing functions you use all the time; quantize, transpose, note velocity, note length, and legato.

RG-8 Arpeggiator

Reason 4 ships with RPG-8, a unit dedicated to the art of arpeggiation. Some arpeggiators are quite content with simply transforming chords into wandering, rhythmic melody lines. The RPG-8 monophonic arpeggiator isn't. With a range of on-panel controls and mode selectors, a pattern section for muting selected notes in an arpeggio, and a large display showing values and positions, this device gives you full creative control over your arpeggios.

Although very hands-on and user friendly, the RPG-8 boasts some very advanced features under the surface that will change how you play Reason's instruments. The Single Note Repeat function engages the arpeggiator only when two or more simultaneous notes are held down”letting you add sudden bursts of arpeggio to your melody lines. The Manual mode will arpeggiate notes strictly in the order they were input, for realtime arpeggio control. Try arpeggiating your breakbeats, orchestra samples, or ReCycled vocals for more dramatic flair.

ReGroove Mixer

If you want your tracks to flow with a less rigid, less programmed feel, a regular shuffle control just doesn't cut it. The ReGroove mixer, Reason 4's realtime groove management device gives you more than just a set of sequencer swing parameters, you can apply its timing magic nondestructively, giving you freedom to adjust its settings and fine-tune your groove as your music is playing.

Lock all your tracks together into one unified feel, or apply different settings to up to 32 musical elements in your song for ultimate control. Each of the groove channels features controls for groove amount, slide, and shuffle, plus more detailed settings. The Reason 4 sound bank comes with a great selection of groove patches, many of them created from analyzed recordings of real musicians, as well as classic groovy tracks.

Thor Polysonic Synthesizer

Thor has the amazing ability to sound like every synthesizer imaginable and like none you've ever heard before too. Where other synths use one specific form of synthesis and one single filter, the Thor polysonic synthesizer features six different oscillator types and four unique filters. This gives you an unstoppable monster of a sound generator that utilizes synthesizer technology from the last 40 years.

Six open filter and oscillator slots let you load up three different synth filters and three separate oscillators simultaneously, allowing you to dial in synth sounds that are completely original. An all-powerful modulation matrix gives you complete control over your signal flow, letting you modulate anything within Thor with anything within Thor.

At the bottom of this synth sits an analog style step sequencer with more than one twist. Being every bit as modular as the rest of Thor's components, this step sequencer does more than just play melodies. It can be used as a modulation tool, to trigger phrases from specific keys, create intense arpeggios, and generate piercing percussion lines. With its unique selection of oscillator types and synth filters, the Thor polysonic synthesizer is a veritable synth museum. It may have one foot in history, but its sound is pure future.


When you install Reason 4, you can now choose between four different language versions: English, French, German, or Japanese. The entire application, from installer to menus and help files, will speak the chosen language.

Factory Sound Bank

Reason 4 wouldn't be a true Reason product without its huge Factory Sound Bank. The Sound Bank holds patches for all devices in Reason to help you get going instantly including Thor patches; more Combinator patches, including arpeggio-driven patches using the RPG-8 arpeggiator; groove files for ReGroove; new ReDrum drum patches; and song starters.

Signature patches

Having the best sounding synth on earth is a lot more fun if you have a set of great patches to play with. Propellerhead invited some of the world's leading synthesists and sound developers to add their own Thor patches to the Reason Sound Bank, including Daniel Wang, Morgan Geist, Pascal Gabriel, Plaid, Richard Barbieri, Richard Devine, Sonic Boom, Tipper, Two Lone Swordsmen, Gordon Reid, and Vengeance.

Tool Window

The new Tools Window is a floating window containing all your most frequently used tools. With it, you can create new devices by choosing from a device palette, fine tune your sequencer data from the Tools pane, or set groove parameters using the groove pane. The device palette lets you drag and drop instruments and effects directly to the rack, placing them just where you want them. The Tools pane contains all of Reason's sequencer editing tools, allowing for quick access to everything from quantization to vector automation cleanup and legato adjustments. When you hit a channel's Edit button in the ReGroove mixer, the selected groove's parameters show up here for instant editing. It's also where you can save your own groove files.

Combinator and NN-XT updates

If you're into making your own sounds, the Combinator and NN-XT devices have both had minor revisions to make programming patches easier and more powerful.

The Combinator now has a function that transposes notes sent to a device which is very handy to create splits. Other additions include performance data filters to stop certain types of data from being sent to a device, more flexible choice of sources in the programmer, and a function to automate the receive notes option, making it possible to switch between instruments in a Combinator patch.

The NN-XT has been given features to edit multiple samples simultaneously, to chromatically auto-map samples, and a Group Mono function to let samples play polyphonically, but still be silenced by other samples in the same sample group.

Best beat making program out..

By Half Dead

from Colorado

Comments about Propellerhead REASON 4.0 Music Production Software:

I have used many programs on the computer and none of them are as easy and filled with so many high quaility sounds as this. I didn't even read the directions, I downloaded it and went right to work. This is all you need to make beats, forget the Korgs, Fantom, and eanything else this has everything you need.

Hands down the best


from Atlanta

Comments about Propellerhead REASON 4.0 Music Production Software:

Reason is the best beat making software available on the computer. I first bought Reason 3 and I fell in love. I was used to using FL Studio XXL but Reason soon made me forget FL. Its not as simple as FL Studio but Reason is more efficient and can help you create a more quality sound. When you use it with a MIDI keyboard, a lot of refills and use it with Pro Tools or something like that - you have a complete studio. If you know how to use it properly, then you can make beats that rival some of the hottest producers today (if you're good at making beats that is) To sum it up - Reason 4.0 is worth the money

Great for Synthetic Sounds.. not so much for naturals

By Mr. V12, Royal Mouf Records

from Atlanta, Ga

Comments about Propellerhead REASON 4.0 Music Production Software:

Reason 4.0 is definately the huge step up if your using on of those basic, yet sometimes effective, pattern sequencers. Reason allows the user to expand the sound of the music, and not be limited in scope and range of the track. Right out the box most of Reason sounds are for lack of a simpler term Wider than any other production software i have used, they dont need much eq'ing or panning. My only problem with Reason is, even though the sounds are good, out the box, Reasons isn't equip with (in my opinion) alot of natural sounding instruments. In my opinion and the opinions of those i am partnered with you cant just open up the brass section of the NN-Xt (for example) and expect a full deep rich and complete brass sound. The sounds are great and better sounding instruments can be made through the combinator and imported through other means. There are some that definately do more than the trick. But others more is desired. I love Reason i use it everyday. it literally is the Reason im where im at musically today. But i almost always use the Rewired feature of Reason so I can integrate my VSTs, Au's, and Rtas plugings especially when I dont feel like building an instrument from the ground up. Reason is definately worth the money I promise if your not using it already your not at your full potential as a producer.

You're missing out if you don't have it.

By T Loh

from Los Wages

Comments about Propellerhead REASON 4.0 Music Production Software:

I first started using Reason 3.0 in summer of 2007. One year later, i upgraded to Reason 4.0 and was completely blown away by how far Propellerhead raised the bar. I gotta say, the best part (at least for me) is the sequencer. Now in 4.0 you have the ability to put time signature changes and tempo changes at will with the click of a mouse. The sequencer's presentation also looks way more enticing than 3.0. While the "natural" sounds aren't really Reason's speciality, there's no denying the fullness of the refills. I have Abbey Roads, Reason Pianos, Reason Drum Kits 2... they're all absolutely amazing. Try the software, you won't be disappointed.


A powerful tool with so many options

By Jeremiah

from Haverhill, MA

Comments about Propellerhead REASON 4.0 Music Production Software:

I became aware of Reason back when it first came out, but stuck with my hardware synths. Once V4 came out, Thor had the power and capabilities to make me switch to software. The program is as deep as you want to make it. You have the power and flexibility of a modular analog synth system but with so many great presets and refills available, you can do a lot without every turning the rack around. The synths are very versatile, the samplers are robust, and the effects are great. If you are looking for an all in one sequencer or want a great add on sequencer/synth system for you DAW, this is a solid product.
