The JOYSTICK allows for altering two bipolar control voltages simultaneously. These
control voltages can be applied to the control parameters on other “modules” e.g.
Oscillator pitch, Filter cutoff frequency, VCA gain and others. The X and Y level
controls define the range of the control voltages where maximum range is -5V to
+5V. The joystick is connected to pins 15 and 16 on the patch matrix, and there’s a
hidden feature – the control voltage from user-defined MIDI CC messages is added
to the Joystick’s voltage. For even more extensive control over parameters on the
instrument, the RECORDING of joystick movements has been implemented. To
record a joystick movement, push and hold the REC/CLEAR button and move the
joystick. You can record up to 8” of motion. Playback starts half a second after the
REC button is released, and the bicolour LEDs will give visual feedback on the CVs
going the output. If you move the joystick during playback, the recorded CV is
overdubbed, and playback resumes in half a second after no motion is detected. To
clear the recording, double tap the REC/CLEAR button. The Joystick module also
features a manual GATE button that controls the TRAPEZOID generator described
above. You also can record a GATE PATTERN – push and hold the REC/CLEAR
button and push the GATE button to record a gate pattern. You can record up to 8”
of gate patterns. To clear the recording, double tap the REC/CLEAR button.
The SYNTRX II has two external audio signal inputs and you can use the instrument
as an FX unit for external signal treatment or to inject the external signal into
advanced patches and generate completely new sounds.
INPUT 1 comes with an input LEVEL attenuator and an ENVELOPE FOLLOWER
(E.F.). The envelope follower will do two things: 1) extract a gate from the incoming
signal, 2) extract the envelope or, in other words, control voltage that follows the
change of the amplitude of the incoming signal. The basics of the envelope follower
operation are shown in the image below. The envelope follower works the best with
audio signals that have beats and it has four controls. The gate THRESHOLD knob
sets the threshold (upper level) of gate detection. A signal below the threshold will be
interpreted as a gate and the LED will turn on to indicate the presence of the gate.
The switch TO GATE sends an extracted gate to the gate ORing circuit, and it’s
added to other incoming gates (one from an external keyboard, internal sequencer
or GATE button). The DECAY knob adjusts the decay time of the envelope – at 0
setting it’s sharp and follows the amplitude of the incoming signal, at more clockwise
settings, the decay time is extended. The EF LEVEL knob is the envelope follower
output CV attenuverter. It determines how much CV is sent to the Env. Follower
output. The Inverted signal (counter clockwise setting of the EF LEVEL knob) is useful
for ducking audio outputs in a beat with a signal applied to INPUT 1. The INPUT1 is
normalled to the SCOPE OUTPUT, so, if nothing is patched into the INPUT 2 jack
socket, a signal from the SCOPE OUTPUT is automatically routed to INPUT 2.
