Optimizing Songs
Below follows things you can check and change to make sure your song uses as little computer processing power
and memory as possible:
Global
• Delete unused devices.
If a device isn’t actually doing anything, delete it from the rack.
• Use fewer devices.
For example, instead of using several similar reverbs as separate insert effects, replace them all with one, set up as
a send effect in the Mixer. By the same token, try to use one sampler playing several different samples instead of
numerous samplers playing one sample each.
• Don’t use stereo unless it is required.
For example, if a sampler or Dr. Octo Rex loop player is playing mono material, only connect the Left output and
leave the Right output unconnected.
Sample Players – NN19, NNXT, Dr. Octo Rex and Redrum
• Only activate High Quality Interpolation when it is required.
Listen to the sound in a context and determine whether you think this setting makes any difference.
• If you are playing back a sample at a much higher pitch than it was recorded at, consider sample rate convert-
ing the actual sample file to a lower sample rate.
This will require an external sample editor with good sample rate conversion facilities.
• Try to refrain from using stereo samples.
Filters – Subtractor, Thor, Malström, NN19, NNXT and Dr. Octo Rex
• Deactivate filters that are not used.
Observe that if the Cutoff is all the way up or the envelope is set to open the filter fully, then the filter doesn’t affect
the sound. Conserve processing power by disabling the filter altogether.
• Where applicable, use the 12dB lowpass filter instead of the 24dB lowpass filter.
See if you can get the same sonic result by using the 12dB filter, since it uses up less processing power.
Polyphonic Devices – Subtractor, Thor, Malström, NN19, NNXT, Dr. Octo Rex and
Redrum
• Try making the device play fewer voices.
This can be done for example by lowering the release and setting the Polyphony setting to exactly the maximum
number of notes played simultaneously by this device.
! Note that just lowering the polyphony setting has no effect. Unused voices do not consume processing power.
• Where applicable, try the Low Bandwidth (Low BW) setting.
This will remove some high frequency content from the sound of this particular device, but often this is not notice-
able (this is especially true for bass sounds).
