Polyphonic Devices – Subtractor, NN19, Dr. Rex
and Redrum
➜ 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.
➜ Try the Low Bandwidth (Low BW) setting.
This will remove some high frequency content from the sound of this par-
ticular device, but often this is not noticeable (this is especially true for
bass sounds).
Subtractor
➜ Try avoiding using Oscillator 2 altogether.
If you can create the sound you need with only one oscillator, this saves
considerable amounts of processing power.
➜ 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 “–”.
➜ Do no activate Noise unless required.
➜ Do not activate Filter 2 unless required.
➜ Do not use FM unless required.
In other words, set the oscillator FM knob to “0” and make sure no modu-
lation source is routed to FM.
Redrum
➜ Do not use the Tone feature available on channel 1, 2 and 9.
In other words, make sure the Tone controls and their accompanying Vel
knobs are set to “0” (“twelve o’ clock”).
Mixer
➜ Avoid using stereo inputs when not required.
For example, if your sampler or Dr. Rex player is playing mono material,
only connect it to the Left input on a mixer channel. Leave the Right input
unconnected.
➜ Do not activate EQ unless required.
If a channel doesn’t make use of EQ, make sure it’s EQ button is deacti-
vated.
Reverb
➜ If you are running out of processing power, try the Low Density al-
gorithm.
This uses up much less power than other algorithms.
Send Effects
➜ When you are using mono effects as send effects, you can connect
the effect returns in mono as well (disconnect the cable to Aux Re-
turn Right on the Mixer).
This is true for the following effects:
• D-11 Distortion.
• ECF-42 Envelope Controlled Filter.
• COMP-01 Compressor.
• PEQ-2 Parametric EQ.
• DDL-1 Delay (provided the Pan parameter is set to center position).
