Reason is a computer program for creating and editing music developed by Swedish software developers Propellerhead Software. It emulates a rack of hardware synthesizers, samplers, signal processors, sequencers, and mixers, all of which can be freely interconnected in an arbitrary manner. Reason can be used either as a complete virtual music studio or as a collection of virtual instruments to be used with other sequencing software in a fashion that mimics "live" performance.

For Mac OS 8.6 to 9.2.2

A note about the downloadable files:

v1.0 serial: RSN100-0000-000158-ALNC-998J-Y2HP
v1.0.1 serial: RSN100-0000-000116-7QUV-FWPC-JSPQ

If installing the 1.0.1 update, after previously installing v1.0 you most likely will have to erase the extensions from the system folder as these files dont seem to be removed or overwritten properly when installing the 1.0.1 update.

Reason 1.0 was released in December 2000. The program's design mimics a studio rack into which users can insert virtual devices such as instruments, effects processors, and mixers. These modules can be controlled from Reason's built-in MIDI sequencer or from other sequencing applications such as Pro Tools, Logic, FL Studio, Reaper, Digital Performer, Cubase.

is there a way to run reason without the cd?

"an easier approach would be to encode to macbinary (.bin)
thats what macbinary format is for..

  • Easiest is not always the best (for me).
    1. MacBinary does not compress.
    2. The larger the file the more the online cost, in both upping & downloading.
    3. It costs personally in both time & money- Especially to those of us who also upload to here, gratis.
    4. Some of us are on a tight budget, with limited resources and slow internet connections.
    5. If a 700 MB ".toast" image gets compressed to a 400 or 500 MB ".sit" archive before upping - All the speedier for both up & downloading.
    6. If a downloaded 700 MB ".bin" file gets unwrapped to a 700 MB ".toast" image, there's 1400 MB's of disk space I need to find temporarily.
    7. And as far as some of the old Macs I run go, disk space is also at a premium.
    8. ".bin" is fine for small archives but for large CD sized archives, compress as ".sit", ".zip", etc, please.

thats what macbinary format is for.. and its alot faster then stuffing or unstuffing a stuffit file
try it;)

--->is it really neccessary to place an iso/toast inside a .sit stuffit archive?<----

Not really, in the sense that a naked iso or toast file will still work OK with Toast. However, by not compressing (whether with sit or zip or other) the file size can be much larger than it might be (but not always true). Another reason I like to use Stuffit is that I make my images in a classic environment with a corresponding file type and icon, and these are retained if you uncompress the sit file back in a classic environment.

Thanks for talking, TheMacMeister, I've created a new d/l mirror for Program disc now. Smile

I have the Sound Bank CD, but the Program Disc mirrors all seem to be gone. Any chance of a reupload?

Phew, last mirror still works, disregard previous comment.

No need to apologize, don't worry. I didn't mean to sound indifferent or negative about it, but i find it very distracting, that's it.

**reason 1.0.1 update is now posted **

Reason 1.0.1 is the first update to Reason, the virtual studio package from Propellerhead Software. This release is focused on perfecting the application before adding new features.

The biggest change in Reason 1.0.1 is the completely rewritten ASIO implementation that will sort the large number of problems with ASIO drivers in Reason 1.0. The new ASIO implementation also features support for external WordClock and S/PDIF sync that wasn't available in Reason 1.0.

Other than that, we have worked on a large number of details to make Reason easier to work with.

Changes in Reason 1.0.1.

* The Audio Preferences settings have been redesigned and now contains some new options. This is due to a thorough audio driver update, including completely rewritten ASIO implementation. New options include enable disable of channels for multi output audio drivers.

* The ReFill packer is now included in the Reason package. This is an application with which to create ReFills for Reason. These can contain patches, samples, Rex files and song files.

* If a cable is dragged to a folded device in order to make a connection, the device will now automatically unfold if the cable is held over the device for a moment.

* The following Transport functions can now be controlled via MIDI or Keyboard Remote Mapping: Stop, Play, FF, Rewind, Record, Loop On/ Off and Automation Override Reset.

* When auditioning a slice in Dr. Rex by holding down [Option] (Mac) or [Alt] (Windows) and clicking on the slice, the pointer now takes on the shape of a speaker symbol.

* It is now possible to audition a sample patch or sample in the NN19 sampler by holding down [Option] (Mac) or [Alt] (Windows) and clicking on a key in the keyboard display.

* There is now an orientation line in the Matrix grid display when clicking and/ or dragging, to make it easier to find the correct note.

* The status of the 'Quantize Notes During Recording' button in the sequencer is now saved in a song.

* It is now possible to cancel any drag and drop operation in Reason by pressing [Esc].

* A problem with Logitech drivers has been resolved. Simply update to the latest drivers (available at if Reason crashes when clicking in the rack.

* In order to protect any copyrighted material that a Published Song may contain, it is not possible to perform Export Song/ Loop as Audio File if a Song has been modified in any way.

* Reason will now not run at all if Virtual Memory is activated under MacOS.

* Published Songs created with Reason 1.0.1 can not be opened in Reason 1.0.

* Changed the alert message that appears if an improper web page address has been entered prior to clicking the 'Launch Browser' button in the Song Information dialog.

* A problem with AudioWerk 2 + 8 ASIO drivers has been resolved.

* The problem where it was sometimes impossible to load a song if it contained samples located on a network disk has been resolved.

* The registration dialog no longer appears if the Reason preferences are missing or corrupt.

* The MIDI Preferences settings have been split up into two sections; MIDI and Advanced MIDI.

* When Reason is used as a ReWire slave together with a ReWire compatible application (such as Cubase, Logic etc.), the Reason Engine now detects if the host application is running low on memory, and Reason then removes unused samples to free up memory.

* If a sample played by the NN19 sampler has its loop endpoint set outside of the actual waveform, NN19 will only play the waveform, ignoring the loop endpoint.

* The Song position and the status of the Loop On/ Off button will no longer sometimes change after executing 'Export Loop as Audio File'.

* The problem with the sequencer where, if the End marker was moved to Song position '0', the End marker would sometimes disappear and Tooltips would pop up has been fixed.

* Reason will no longer occasionally crash if you change the Sample Rate in the Preferences- Audio dialog.

* The voice allocation problem in the Redrum device has been resolved.

* The different lanes in sequencer Edit Mode are now sorted properly.

* The pop-up menus for the MIDI Channel buttons in the Hardware interface have been moved down. This is to reduce the risk of accidentally selecting something from the menus when clicking the buttons.

* If a song contains a sample that for some reason can not be read (bad format, corrupt file etc.), it was previously impossible to load the song. This has been fixed. Reason now shows an alert about the faulty file, and continues to load the song.

* The Reason browser now by default start in the application folder rather than the desktop.
When a song is saved or published, Reason will now perform a verification process to assure that the song was saved properly. This will prevent situations where files go corrupt due to media failures.

* There was a problem with Dr. Rex, where a song could not be loaded if a Rex file was changed or incorrectly identified. This has been fixed. Reason will now show an alert stating that the Rex file can not be loaded, but continues to load the song.

* MIDI Remote Controller Mapping now handles On/ Off controls (such as Mute and Solo buttons) by toggling the control when the MIDI Controller value reaches 127.

* Upon startup, Reason checks and verifies which version of the Reason Engine is present in the system. Running Reason 1.0.1 with a Reason Engine from version 1.0 might cause the program to crash.

* Some minor problems with file type definitions have been fixed.
