7-fold Manual Ribbon Gate
The right picture shows an application of the A-152 in
combination with the ribbon controller A-198. The posi-
tion control voltage of the A-198 is used to address the
A-152. If the manual address control and the CV at-
tenuator are adjusted in the right way the position sensor
of the A-198 covers the complete address range of the
A-152 and a small share of the position range is assi-
gned to one of the eight addresses of the A-152.
If the hold switch of the A-198 is set "off" the A-152
jumps to address 1 as soon as the finger is removed
from the position sensor. As soon as the sensor is
touched, one of the stages in the range 2...8 is addres-
sed and the corresponding digital output turns to "high" -
displayed by the corresponding LED. This leads to a
7-fold manual gate generator that can be operated like a
percussion set. According to the position of the finger,
that touches the position sensor of the A-198 one of the
gate outputs of the A-152 is active. The gate outputs
may be used to trigger percussive sounds stored in an
A-112 sampler module or percussive patches based on
other A-100 modules.
In principle the gate outputs can be used for any gate/
trigger/clock function in the A-100.
In the example the position CV is also patched to the
common T&H input. At the T&H outputs control voltages
are available that follow the position CV of the A-198 in a
certain range. As soon as the finger leaves the corre-
sponding range the last voltage is stored.
The multiplexer unit can be used for additional switching
functions (e.g. to connect different modulation or audio
sources to a module).
