CPU Usage Limit
Reason is a very powerful program which was designed to be as light on processing power as possible - without
compromising on sound quality. Nevertheless, the more devices you use in your song, the more of your computer’s
resources it will use.
The CPU Usage Limit setting allows you to set a limit on how much of the CPU (computer processor) that should be
used for creating audio. The remaining capacity is reserved 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.
Load Default Sound in New Devices
When this is activated and you create a new device (of a device type that supports patches), a default patch will be
loaded. This way you can be sure that a new device generates sound right away. The default sound will also deter-
mine the default location in the Factory Sound Bank when you browse for patches for the new device.
If you turn this off, new devices will be initialized - parameters are reset to their default values and no samples are
loaded in sample-based devices.
! Note that “Sound” also implies patches for effect devices such as the RV7000 and Scream 4.
Use MultiCore Audio Rendering
Reason fully supports MultiCore Audio Rendering. This means that if your computer has multiple CPU cores (dual-
core or quad-core, for example), or multiple CPUs, Reason takes advantage of this to significantly enhance the per-
formance. If your computer has a multi-core CPU, or multiple CPUs, MultiCore Audio Rendering is active by default.
See “Audio Basics” for more information on how Reason handles audio.
Self-contain Samples When Loading From Disk
When this is activated, any samples you load into a sampler device from disk will automatically become self-contained
and saved together with the rest of the song data when you save your Song.
