Overview
Well, it's a joystick, isn't it? A basic joystick is used to provide an
easily-varied control voltage (CV) to other modules, often allowing the input
of a DC CV that is then either amplified or attenuated by the joystick before
being sent out to other modules.
The Choices joystick is designed to have as much utility as possible
while keeping the price down. Offering only DC control seemed improper,
so the Choices was configured to operate with AC input as well as DC. A
brief rundown of the features:
It can be oriented with joystick at the top or the bottom to best suit
•
its location in your system.
Separate Gate and Trigger outputs
•
Two trigger buttons for ease of ambidextrous access, regardless of
•
orientation.
Toggle switches to select optimal reference level for either AC or
•
DC inputs.
Usage Details
Supply: This design has been tested from ±9V up to ±15V and
works well in this range, although performance specifics will vary with
supply voltage. All measurements, unless stated otherwise, assume V
supply
= ±12V. All units have a polarized or shrouded power header to ensure
proper connection. Supply polarity symbols are also silkscreened on the
PCB in case of non-standard cables or supply bus.
Orientation: Choices is configured to operate with the joystick at the
top by default. If you wish to rotate the unit, the output will be reversed in
respect to the operation of the joystick - up will decrease, down increase, left
increase, right decrease. To correct this, simply unplug the green connectors
that are connected to the joystick, rotate them 180° and plug them back
in.
Joystick tension/mobility: All joysticks have a clear silicon lubricant
applied to the ball joint during assembly for ease of motion. If the motion
becomes "dry" over time, lube it up baby. Electronic control lubricant is
recommended.
Each joystick assembly is slightly different in its physical
