FLIGHT OF HARMONY CHOICES JOYSTICK EURORACK MODULAR MODULE

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 regular control potentiometer has 310° of rotation, while the standard joystick has only a 60° arc of travel to cover the same amount of resistance, that’s 1/5th of the resolution! But we can do better than that: Choices uses a joystick assembly that has 90° arc of travel, and is the smoothest-feeling joystick I have ever found.

The Choices joystick module was designed to pack as much utility as possible in as little space as possible while keeping the price as low as possible, keeping with the design philosophy of f(h). 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 Joystick

Moving the joystick operates two 100k potentiometers simultaneously, providing a buffered DC Control Voltage (CV) to the outputs; the X output varies with horizontal motion, the Y with vertical motion.

Control

Switched phone jacks disconnect the internal control connection from the power supply to the jack when an external signal is connected to an input. It can handle both DC and AC signals: Each axis has a toggle switch to set the reference calibration for either type.

The Functions

Use Scale control to adjust output magnitude, from 0 to 200%, and Offset control – A.K.A. Bias – to shift signal DC level by up to ±5V.

Trigger Action

Separate Gate and Trigger outputs are employed as well as Dual trigger buttons, so that one is in easy reach no matter what orientation the panel is in or whether you are left- or right-handed.
