Simply plug the sound source into the rear panel EXT1 socket.
Turn the mixer control EXT/NOISE to EXT, 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 THRU (ON). This will leave the VCA open so a constant
signal can be heard.
Finally, play around with the filter and modulation settings as neccessary.
The VCO signals can also be introduced, and use the various VCA modes and enve-
lopes if you wish to contour the sound level and add additional effects.
ENVELOPE GENERATORS
LED indicators
These will turn on each time the EGs
are triggered.
EG1/2 ASR
EG1 and EG2 are identical. They are
ASR (attack / sustain / release) envelope
generators. Use to modulate various param-
eters of the synthesiser.
ATTACK
Controls the Attack time. This is the rate
at which the envelope signal will take to reach
full level when the MIDI note/key pressed.
DECAY / REL
Controls the Decay or the Release time
- the time it take the envelope signal to return
to zero when the key is released.
SUSTAIN
If this switch is on, then the DECAY /
REL control becomes Release. If a key is
held down, the EG is sustained at full level.
If this switch is off, then the DECAY /
REL control becomes Decay. There will be
no sustain.
Note: this switch has 4 positions. The left 2 positions turn SUSTAIN off, and the right
2 on. We are unable to get 2 way switches for the series of potentiometers/switches that
we use.
