Filtering External Sound Sources

External sound sources, such as vocals, guitars, mixer sends, samplers, etc. can be sent through the filter
for extra treatment. Note, mic's and guitars may need pre-amping use if the signal is too quiet.

Simply plug the sound source into the front panel EXT4 socket.

Turn the mixer control Noise/EXT4 to EXT4, and up to a suitable level.

You may wish to return the VCO1 and VCO2 mixer controls to their centre positions so the VCOs cannot be
heard.

Turn the VCA mode switch to ON. This will leave the VCA open so a constant signal can be heard.
Finally, play around with the filter and modulation settings as necessary.

The VCO signals can also be introduced, and use the various VCA modes and envelopes if you wish to
contour the sound level and add additional effects.

Note; The rear panel input sockets are wired direct to the mixer input.

- Filter Type rotary switch

This selects the modulation source that will affect
the filter cut-off

LP

Low Pass: signals above the cut-off
frequency are attenuated 12dB/octave

BP

Band Pass: signals above and below the
cut-off

frequency

are

attenuated

12dB/octave.

HP

High Pass: signals below the cut-off
frequency are attenuated 12dB/octave.

Notch

Notch: signals at the cut-off frequency
are attenuated 12dB/octave

 - MIDI1/MIDI2 MOD amount

Turning the control clockwise will increase the
amount that MIDI2 (CV2 MIDI controller/ velocity)
will modulate the cut-off frequency.

Turning the control anti-clockwise will increase
the amount that MIDI1 (CV1 MIDI note/pitch) will
modulate the cut-off frequency.

In a central position MIDI1/2 will not affect cut-off
modulation
