OPTIMIZING PERFORMANCE

141

General procedure

The basic procedure for optimizing the latency is the following:

1. Open a song and start playback.

You want to choose a song that is reasonably demanding, i.e. with more than just

a few tracks and devices.

2. Open the Preferences dialog.

Under Mac OS X, this is found on the Reason menu; under Windows it’s found on

the Edit menu.

3. Select the Audio page and locate the buffer settings.

If you are using an ASIO driver, you need to click the ASIO Control Panel button,

for Mac OS X/Built-in audio, Windows/MME or DirectX you should use the Buffer

Size slider.

! If you are making adjustments in the ASIO Control Panel for hardware

with an ASIO driver, you should make a note of the current buffer set-

tings before changing them.

4. While the song is playing, listen closely for pops and clicks and try lowering

the latency (buffer size/number).

5. When you get pops and clicks, raise the latency value a bit.

6. Close the Preferences dialog (and ASIO Control Panel, if open).

About Latency Compensation

In the lower right corner of the Preferences-Audio dialog, you will find a setting called

Latency Compensation. This value is used internally in Reason to compensate for the

latency when synchronizing Reason to another MIDI sequencer or similar. Usually, La-

tency Compensation is set to the same value as the Output Latency, but it is possible

to increase it (see page 131). Normally however, you shouldn’t need to touch this pa-

rameter.

Optimizing Your Computer

System

In this manual we do not have the possibility to give you detailed procedures for opti-

mizing your computer for maximum power. This is a subject that we could write com-

plete books on! However, we’d like to share a couple of important tips:

D Quit other programs that are running at the same time as Reason.

D Remove background tasks on your computer.

This might be any background utilities you have installed as well as networking,

background internet activities etc.

D Under Windows, make sure you use the latest and most efficient driver

for your audio card.

Generally, ASIO drivers are the most efficient, followed by DirectX and last MME.

D Only work on one Reason document at a time.

Songs that are open in the background do consume some processing power even

though they’re not playing.

D Lower the sample rate setting in the Preferences dialog.

While this also reduces sound quality, it is a very quick and convenient way to try

to play a song that your computer otherwise can’t handle.
