Using both inputs, more complex envelopes are possible. For example,
during the sustain time set up by a GATE pulse, a trigger received at the
[TRIGGER] will cause a new attack to start.
While in the sustain mode of an envelope, the
will respond to changing
control voltages at it’s [SUSTAIN] input. This makes complicated sustains
possible.

. The
can be thought of
as two separate but interconnected modules: the Sequencer and the
Keyboard. The sequencer can be used by itself by removing the
and its
umbilical cord.
The
provides the user with four voltage outputs [A], [B], [C] & [D], and
[VC TOUCH] which output a voltage depending on which keypad was last
pressed. Each keypad can be assigned a voltage such that keypad [1] has
the lowest voltage, keypad [2] the second lowest and so on up to keypad [8]
which has the highest voltage. Setting the voltage increase between any two
adjacent keys to an equal voltage, allows the
to be used as an equal-
tempered scale keyboard. A processor or processing input can be used to
calibrate an oscillator to produce any desired equal-tempered scale including
the western 12 divisions to the octave.
