Question about Propellerhead Reason 4.0 - Windows and Mac Upgrade Version for PC, Mac

Launching problem Reason 4

I installed a reduced version of Windows to increase speed on my operationg system. When I installed reason 4 (that worked perfectly on my old, "full" windows) I can't start it. The installation seems to do ok, but when I try to launch the program I get the error "File not found" "The operation could not be completed because a file could not be found"

I guess there's some process or service missing in my windows installation, but I'm unable to figure out which one.

When i click on the reason 3.0 icon it says unable to open because of an unexpected error plz help

Reason 3.0 is quite old now and may not be supported by some current OS configurations. Your best bet would be to uninstall it, reinstall and before launching the program, update it to the latest revision release from:
You may also have to right click the icon and select compatibility mode and set it to windows XP if running it on a PC. If you are using the MAC version, about all you can do is make sure you are running the latest revision.
Being you have an older version, you should be able to get a discount when ordering the latest online. Version 5 is packed with new features, I love it!

    b. Select "Properties"
    c. Find where it says "Theme:" Underneath this, click the drop-down arrow, and select "Windows Classic"

    c. Double-click the "System" icon
    d. Click the "Advanced" tab

    j. Click "OK"
    k. Click "OK"
    l. Click "OK"

    Reason: Hard drive is accessed less often, making it faster (note this comes with the price of making file searches slower. If you use the search box frequently, you may want to leave this checked. Otherwise, uncheck it.)
  8. Step 7Determine What Version of Internet Explorer You Have:
    a. Open Internet Explorer
    b. Select "Help," and then "About"

Reason 4 install prob

If you installed Reason 4 and the first time it asked for the DVD and you did not have it, you may need to re-install it and then have the disc ready. This happened to me the first time, and I had to re-install the program. It's just part of the copy-protection.

Hope this helps!

Notes don't stop even after I release the key

The keyboard  is not sending a note off instruction after the key is released. Try checking midi preferences in reason.If your using a Mac check that the edirol is present by launching Audio MIDI Setup utility located in the utilities folder. You can download the latest Mac driver from Roland below: EDIROL PCR-300 32-key MIDI Keyboard Controller :: Download

Midi Trouble with Reason

It is possible that your PC is too slow, but there may
(of course) be other causes

I have experienced a situation with Adobe Audition, causing
recording drop-outs when my PC got too busy.

To test this theory:

1) Shut down all unnecessary applications.

2) Go to the command prompt and disable the internet:

type: IPCONFIG /release.

to restart it later, reboot the machine or type:

3) Go to the task manager and stop all unnecessary

press: control-alt-del at the same time and then

choose the "processes" tab

right click on each process you don't need
and stop the process

4) You should be able to reduce the number of processes
into the low 20's, but you need to keep the following:

a) Your midi application (Reason etc) of course

b) alg.exe
svchost.exe (all of them)
system idle process

5) Now go into the control panel --> administrative tools ->
services and stop all unneeded services

(the system will not let you stop anything essential)

6) Don't worry about stopping tasks and services,
they will all restart to normal when you reboot the

7) Go back into the task manager and right-click your
midi-application. Increase its priority to HIGH,

but NOT real time, because this may cause windows
to hang.

8) If your midi acquisition improves, then speed is the problem,
otherwise, look elsewhere:

a) re-install audio and midi drivers
b) make sure the mixer and control applets are correctly
configured, i.e make sure the midi is not muted.
e) make sure the midi application is allocated the
max amount of memory, if it has a setting for it.


9) I am assuming that you are running Windows XP.

If your PC is too slow do NOT use Vista !!!!,
which makes things much worse, at least
by a factor of 4 to 1

Do not install XP service pack 3 either,
its bloated with anti-piracy **** and DRM.

10) Finally, for audio work, I would recommend
a minimum system with:

a) Pentium III 800 MHz or better yet a Pentium IV
at 1.5 GHz or faster.

b) One Gbyte of RAM to make sure your machine is not
disk bound. This is much more important than a fast

Disk is approx. 10 million times slower than RAM,
so this can become a very significant bottle neck.

c) Windows XP pro, SP2 (not 3)

d) Depending on your video card, i.e. the amount of
workload it handles for the CPU, you may also reduce
the screen resolution, and disable desktop effects
to speed thing up.

Adobe audition, for example will perform more reliably
on slower CPU's when the GUI window is kept small
in waveform or spectrum display during recording.

Good luck,


P.S. I use Adobe Audition for most of my recording and
audio processing. System = Core 2 Duo /2.4 Ghz,
4 Gigs of RAM (only 3 Gigs are accessible from 32 bit
windows XP), 1300 Mhz front side bus, 3.5 Terra Bytes
of hard disk, of which 1.5 Terabytes are configured as

Speed and storage is no longer an issue :)
not even for HD video processing.
