CPU Usage Limit
Reason is a powerful program but also demanding in terms of processing power. The
more devices you add to your rack, the more of your computer’s resources it will use.
Furthermore, as you use more and more of your computer resources for creating au-
dio, less will be available for the user interface, resulting in slower performance in
terms of graphics and overall responsiveness.
The CPU Usage Limit setting allows you to set a limit on how much of the CPU (com-
puter processor) that can be used for creating audio. The remaining capacity is re-
served for the user interface and the graphics.
Set this so that you feel comfortable using the program, even when a very demanding
song document is played back.
Use High Resolution Samples
Reason has the capability to play back samples with practically any resolution. This
means that if for instance 24-bit samples are loaded in a sampler or the Redrum, play-
back of the samples can be in 24-bit resolution as well. If you are using such samples
and want Reason to play them back in their original high resolution, make sure that
this checkbox is ticked.
If this is activated, and if your audio card supports it, Reason will play back high reso-
lution samples in their original resolution. If this option is not activated, Reason will
play back all samples in 16-bit resolution, regardless of their original resolution.
Preferences – Audio
Master Tune
This lets you adjust the global tuning in Reason. Standard tuning is “middle A” at 440
Hz. You can adjust this by +/- 100 cents.
Audio Card Driver – Windows
This menu lists all the available Audio Card Drivers on your system, and lets you select
which one Reason should use. Which option to select depends on the audio hard-
ware:
D If you are using audio hardware for which there is a specific ASIO driver,
you should select this.
With an ASIO driver written specifically for the audio hardware you will get lower
latency (see below), support for higher sampling frequencies (up to 96 kHz in 24
bit/32 bit float resolution), and possibly better support for additional hardware fea-
tures such as multiple outputs.
