DOEPFER / A-174-4 3D Joystick

Variations

A-174-4 Joy Stick II is a controller module that generates multiple CVs and Gates with joystick tilt and rotation.

In addition to “tilting” the joystick in the X/Y directions, as with most spring-loaded joysticks, a third CV, Z, is generated by rotating the joystick itself like a knob. In addition, pressing the button at the top center of the joystick generates a gate signal. An additional function is to generate four CVs assigned to four quadrants separated by X and Y lines. These quadrant CVs are derived from the X and Y voltages by a special algorithm.

Normal (X+OX, Y+OY, Z+OZ) and inverted (-X+OX, -Y+OY, -Z+OZ) outputs with offset control
Normal (X+OX, Y+OY, Z+OZ) and inverted (-X+OX, -Y+OY, -Z+OZ) outputs are available for the joystick. The joystick outputs are bipolar, ranging from a normal CV of -5V (lowest position) through 0V (middle position) to +5V (highest position).

To this CV, three small offset control knobs OX, OY, and OZ can be used to add a variable voltage of up to 5V to the normal CV. The maximum offset control can be used to change the normal CV output range (-5V ~ 0V ~ +5V) to 0V ~ +10V. If the OX, OY, or OZ knob is turned fully counterclockwise, no offset voltage is added and “pure” CV is output; turning the OX, OY, or OZ knob clockwise will add up to 5 V of offset voltage to the normal voltage. V is added to the normal voltage when the OX, OY, or OZ knob is turned clockwise. Offset voltages are also added to the inverted outputs (-X, -Y, -Z), so setting the offset control to maximum will change the CV output range from normal (+5V ~ 0V ~ -5V) to +10V ~ 0V.

Dual color LEDs (red/yellow) are provided for each output to indicate the current voltage and to distinguish between positive (red) and negative (yellow) voltages.

Overlapable quadrant outputs (Q1, Q2, Q3, Q4)
An additional quadrant output (Q1, Q2, Q3, Q4) is provided to generate CV with a different algorithm than the six outputs. When the joystick is tilted toward one of the four quadrants separated by the X and Y lines of the joystick, a positive value of CV is output from the quadrant output corresponding to that direction. The Quadrant Overlap control allows the CVs between the quadrants to overlap. When the overlap is set to 0, CV is output only from the quadrant in the direction in which the joystick is currently tilted, while the other quadrant outputs remain at 0V. As the overlap control is increased, the voltages will gradually overlap. For example, as the overlap control is increased, CV is output from both Q1 and Q2 when the joystick is tilted toward 12 o'clock. Increasing the overlap control increases the amount of overlap. A single-color LED is provided for each quadrant output to indicate the current voltage. The quadrant outputs output only positive values of CV.

IMPORTANT NOTE
Because the joystick is 7 cm long from the panel to the tip, the lid cannot be closed when mounted in a portable case (A-100P6, A-100P9, A-100PMS6, A-100PMS9, A-100PMS12) that can be carried with a lid. It can be mounted on portable base cases (A-100PB, A-100PMB) and all cases without lids without any problem.
