Optimizing Songs
Below follows things you can check and change to make sure your song uses as
little computer processing power as possible:
Global
D Delete unused devices.
If a device isn’t actually doing anything, delete it from the rack.
D Use fewer devices.
For example, instead of using several reverbs as insert effects, replace them
all with one, set up as a send effect. By the same token, try to use one sam-
pler playing several different samples instead of numerous samplers playing
one sample each.
D Don’t use stereo unless it is required.
For example, if a sampler or Dr. Rex player is playing mono material, only
connect the Left output and leave the Right output unconnected.
Sample Players – NN19, NNXT, Dr. Rex and
Redrum
D 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. However, note that on a Macintosh G4, High Quality
Interpolation does not require any more processing power.
D If you are playing back a sample at a much higher pitch than it was
recorded at, consider sample rate converting the actual sample file
to a lower sample rate.
This will require an external sample editor with good sample rate conversion
facilities.
D Try to refrain from using stereo samples.
Filters – Subtractor, Malström, NN19, NNXT and
Dr. Rex
D 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.
D 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, Malström,
NN19, NNXT, Dr. Rex and Redrum
D Try making the device play fewer voices.
This can be done for example by lowering the release and setting the Po-
lyphony setting to exactly the maximum number of notes played simulta-
neously by this device.
✪ Please note that just lowering the polyphony setting has no effect.
Unused voices do not consume processing power.
D Where applicable, try the Low Bandwidth (Low BW) setting.
This will remove some high frequency content from the sound of this partic-
ular device, but often this is not noticeable (this is especially true for bass
sounds).
Subtractor
D Try avoiding using Oscillator 2 altogether.
If you can create the sound you need with only one oscillator, this saves con-
siderable amounts of processing power.
D Do not use the oscillator Phase mode if you don’t need it.
In other words, set the Oscillator Mode switches to “o”, not “
*
” or “–”.
D Do no activate Noise unless required.
D Do not activate Filter 2 unless required.
D Do not use FM unless required.
In other words, set the oscillator FM knob to “0” and make sure no modula-
tion source is routed to FM.
Malström
D If it isn’t necessary, refrain from using Osc B at all.
If you can produce the desired sound by using Osc A only, this will save a lot
of processing power.
D If one or both Oscillators are routed to one Filter only, and/or the
Spread parameter is set to “0”, only connect one of the outputs (the
one to which the filter is connected) to the mixer, and leave the
other one unconnected.
D Try to see if you can achieve the desired effect by using only one of
the filters, and without using the shaper.
Using both of the filters and the shaper in conjunction requires considerably
more processing power than using just one of the filters and/or the shaper.
