Introduction

The SY02 is a multimode filter with a difference. There are separate cut-off and resonance controls for both the hpf and the LPF. This means you can use the SY02 as a LPF, a HPF, or by combining the two you get a BPF. When used as a BPF, it has the advantage over others in that you have control over the band width and the added advantage of two separate resonance controls.

The SY02 can be used on its own as a filter (by turning up the Initial Level0, but it includes a VCA, this means straight away it can be used with envelopes, without the need of a separate VCA.

 

Controls

Input Level

This sets the input level of the audio signal into the filters.

HPF CV

This sets the level of external CV that affects the HPF cut-off. Set at minimum, the external CV has no effect, set at maximum, the external CV has full effect.

LPF CV

This sets the level of external CV that affects the HPF cut-off. Set at minimum, the external CV has no effect, set at maximum, the external CV has full effect.

Initial Level

This sets the initial level of the VCA. It applies a voltage to the VCA that opens it up. Set to maximum, the VCA will pass signals through at full volume. This would be the normal way of using this control. As the control is turned to minimum, the level of the VCA decrease finally to zero. In this case, an external CV is used to control the VCA level (such as an envelope signal).

HPF Cut-Off

This control sets the cut-off frequency of the HPF. As the controls is increased, more lower frequencies are filtered out (only high frequencies are allowed to pass through).

HPF Resonance

This alters the resonance of the HPF. Set to maximum it will self-oscillate producing a continuous sinewave. In this way the SY02 can be used as a VCO.

LPF Cut-Off

This control sets the cut-off frequency of the LPF. As the controls is increased, more higher frequencies are filtered out (only low frequencies are allowed to pass through).

LPF Resonance

This alters the resonance of the LPF. Set to maximum it will self-oscillate producing a continuous sinewave. In this way the SY02 can be used as a VCO.

Volume

This sets the final output volume of the SY02.
