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 hardware:
DD
DD
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 addi-
tional hardware features such as multiple outputs.
DD
DD
If there is no specific ASIO driver, you should select the Direct
Sound driver for the audio hardware.
This makes Reason communicate with the hardware via Direct Sound (a part
of the Microsoft DirectX package). For this to be possible, you need to have
DirectX installed on your computer, and there must be a Direct Sound driver
for the audio hardware.
DD
DD
If the audio hardware doesn’t support Direct Sound (i.e. there is no
Direct Sound driver for the audio hardware), select the MME driver
for the audio hardware.
