relay with a controlled duration of stay in the active state, and some additional functions
which will be described later.
Let’s compare ORNAMENT to a mechanical system in which pulses are transmitted, such
as in billiards. A billiard ball rolls in the free state for a certain amount of time until it hits
another ball, and transfers the pulse to that ball. In ORNAMENT, each cell is like a billiard
ball, and the capacitor charge time is the time of free movement of the ball from the mo‑
ment a pulse was transmitted to it until it encounters the next ball, transmitting the pulse
to it. Looking at the ORNAMENT as a system in which pulses are transmitted with a certain
delay will help to master it faster and more fully, therefore we will return to this analogy in
further explanations.
What if the trigger pulse arrives at an already active cell?
To prevent such a pulse being "wasted in vain" we added an additional output PASS , to
which this pulse is transmitted if the cell is already active. Aside from saving the pulse, this
output also allows you to branch ORNAMENT behavior algorithms by sending pulses to the
TRIG or PASS outputs, depending on whether these cells are active or not.
In order to provide an additional option for discrete control of the cell delay time, we added
an input
X2
. When a voltage is applied to it of more than 1 volt, it connects an additional
capacitor of the same capacity in parallel with the main capacitor of the cell. Thus, the charge
time and, accordingly, the cell activity and pulse delay times are doubled.
This function has one feature that makes its effect on the operation of the ORNAMENT
more complex: at the time of removing the voltage from X2 and disconnecting the addi‑
tional capacitor from the main capacitor, some voltage may remain on it if the disconnection
occurred during the phase of cell activity. At the time of the next supply of voltage to X2
and the connection of an additional capacitor, the charges of both capacitors will equalize
and will be equal to the sum of their charges divided by two. Thus, the cell activity time may
be less than TIME x 2. We can say that the function X2 remembers the state of the cell at
the last moment of the function’s activity.
The result of the cell activity can be obtained at its three outputs:
CV output — the voltage on it is equal to the voltage on the capacitor and can vary from
0 to 10 volts.
LYRA
output — during cell activity is connected to the ground (GND pin).
PULSAR output — in the active state, the output voltage is 10 volts, in the inactive state,
the output is 0 volts.
The phase switch allows you to invert the state of the cell outputs (lower position) or turn
them off completely and make the cell in the musical sense a pause generator (middle position).
The SET button activates the cell, as does a negative pulse at the TRIG input. These but‑
tons are used for bringing the ORNAMENT patch you created into motion. Pressing them
is the equivalent of cue strikes on selected billiard balls in our mechanical model. Thus, by
using the SET buttons, you can add pulses to the ORNAMENT system.
While you hold the SET button, the cell will be active, even if the capacitor is already
fully charged (i.e longer than set by the TIME knob).
The RESET button puts the cell in an inactive state from any phase of activity. Using these
buttons you can reduce the number of pulses in the ORNAMENT system.
