RHYTHM DESIGNER RD-9 User Manual

9. Wave Designer

Wave Designer is a powerful tool for adjusting signal transients and dynamics,

such as attack and sustain. Use the Wave Designer to make a snare drum really

“crack” in the mix, or to expand the bass drum to be even more devastating.

With both ATTACK and SUSTAIN controls set to 12 o’clock the Wave Designer

is essentially in bypass and will not affect any voices being sent to the Wave

Designer via the bus.
Adjusting the ATTACK knob will make the opening transient of the voice sound

punchier. Increasing the SUSTAIN control acts in a similar way as a compressor,

allowing the peaks to carry on longer before decay. The effect can also be used to

reduce the sustain for a more staccato sound.

NOTE:

Using a long sustain on naturally staccato sounds (i.e., Rim Shot) may

cause noise. Dial this noise out by reducing the sustain amount.
All voices sent to the Wave Designer as described will then pass into the Analog

Filter section to be processed.
The SIG LED shows that a signal is present in the Analog Filter/Wave Designer bus.
The SEND button activates the Wave Designer circuit.
How to assign voices to the FX bus:

Press SEND in the FX sections (flashes orange).

Use SELECT to assign which voices go to the bus (solid pink LED

indicates voice sent to the FX bus).

Press SEND in the FX section to exit. SEND button will be

solid white to show voices are assigned to the FX bus.

TIP:

Hold TAP/HOLD while pressing SEND to clear all voice from the FX bus.

The diagram below shows the audio routing of the voices as they pass through

the RD-9. Only one voice is shown in this example, but the same process applies

to all voices.

10. Analog Filter

The Analog Filter (VCF) section works on selected sounds routed via an audio bus

fed from the Wave Designer circuit.
The CUTOFF control sets the frequency where the filter is applied. The filter cut off

can be programmed and automated (when the ON button is flashing, automation

is active).
When the HPF (High Pass Filter) button is engaged the filter cuts the the low

frequency cutoff point as you turn the control CW. When the HPF button is not

engaged, the CUTOFF knob defaults to a low-pass filter (LPF), which gradually

cuts the high frequencies as you turn the control CCW.
Press the ON button to activate the filter circuit.
The RESONANCE control adjusts the resonance of the filter. Turning CW adds a

peak at the cutoff frequency that accents the surrounding frequencies.
The filter CUTOFF control setting can be recorded as automation. After

programming a pattern, add the voice or voices you wish to be processed by the

Analog Filter and Wave Designer bus as described earlier in this manual. Next,

while the pattern is playing and in Record Mode, rotate the CUTOFF knob and

listen to the results. Once you are happy with your filter sweep exit Record Mode.

Next time you play the pattern, the recorded filter sweep will play back.
Live Filter Mode can be toggled on and off, and this toggling action gives you

either manual control of the filter frequency or automated Filter Mode, which

uses the stored filter automation data. The live Filter Mode can be toggled on and

off by holding the TAP/HOLD button and pressing the filter ON button to activate

different states:

• •

Flashing filter ON button= Filter plays stored automation data

• •

Solid filter ON button = Filter in live control mode

At any time, you can drop into Record Mode and adjust the filter settings that will

be stored with the current pattern, as long as the filter settings are set to Pattern

(see SETTINGS 11.5 below).
It is also possible to manually program the filter per step or to edit a recorded

filter sweep.
