ISCONNECTING A CABLE
An Oscillator gives a continuous output and needs something extra to give it a loudness contour or
envelope, to cause a Patch to only make sound when a key is pressed on the keyboard. For this you need
an extra module inbetween the Oscillator output and the Output module input. First disconnect the
cables. Do this by doubleclicking on one of the circular input connectors on the 2-Out module and
keeping the mousebutton pressed on the second click. Now slowly drag the mouse away from the circular
input connector onto the grey background of the Patch and release the mousebutton. If all went well the
cable has disappeared. Disconnect the cable on the other circular input connector in the same way.

Select the Module Group selector named E
the Voice Area inbetween the OscDual module and the 2-Out module. Notice that the new module will
'push' the other modules away if there seems not enough space between the already placed modules. This
is to prevent that modules would overlap and maybe become invisible. In fact it is impossible for modules
to overlap, the Editor will not allow this.
Now make connections from the E
blue output connector that is in the lower righthand corner of
the module to both circular input connectors of the 2-Out
module. Next step is to connect the squared red output of
the OscDual module to the circular blue input at the top
righthand corner of the EnvADSR module. Notice that
when you connect a red output to a blue input the blue
input changes to a red color and the blue output on the
same module changes to red as well. This red color
indicates that this module will now process signals at
the highest audio quality.
At this point the patch should look like the illustration. Notice that you don't hear any sound, as the
E
ADSR isolates the OscDual from the outputs. However, when you now press a key on the keyboard
NV
you will hear a note play as long as you hold the key.
This shows one of the basics of modular synthesis, the OscDual module and the EnvADSR module work
together to do a musically sensible thing, each doing its own thing in the sound: the Oscillator defines
the pitch and the Envelope defines the loudness contour.
Have a closer look at the E
knobs define the form of the loudness contour. Click and hold the mouse on the rightmost knob named
R and try to turn it so the display reads 1.60s. Again play some notes on the keyboard. You hear how the
played notes die out more slowly after you released the key.

At this point the patch plays monophonic. With the Voice Mode setting you can easily
assign more voices to this Patch. Click on the upper triangle button next to the Voice
mode display until it shows eight voices.
When playing the keyboard you will notice that now you can play chords and the dying
out of the voices will overlap new notes.
The actual polyphony of a Patch is displayed in the Voice Mode display box. The requested number of
voices is displayed within parenthesis. The system assigns the highest possible amount of voices to the
Patch when your request for polyphony exceed the actual capacity of the Sound engine. In practice many
traditional polyphonic synthesizer sounds can be played with six to eight voices of polyphony, the
amount of voices one would typically find on a traditional analog polysynth.
