Introduction
The SY02 is a multimode filter with a dif fer ence.
There are separate cut-off and res o nance con trols
for both the HPF and the LPF. This means you can
use the SY02 as a LPF, a HPF, or by com bin ing 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 ad van tage of two
sep a rate resonance controls.
The SY02 can be used on its own as a filter (by
turning up the Initial Level), but it in cludes a VCA, this
means straight away it can be used with en ve lopes,
with out the need of a sep a rate VCA.
The filter types used in the SY02 are 12dB roll-
off filters very similar to those used in the classic
Korg MS20.
General Use
Overdrive
The controls have not been limited, so with
certain level settings, especially Resonance, over-
driven sounds are possible. This is great for a nice
dirty distorted sound. If overdriven sounds are not
required, simply decrease the Input level or Reso-
nance level.
No Sounds
There are certain settings that will result in no audio output. Apart from the obvious (initial, input or output level at
zero), this may occur when HPF cut-off is set very high and LPF cut-off set very low. This is basically due to ALL the
audio being filtered out!
