Knob 2
[ Turn] Step Wave Total Step
Specifies the total number of steps to occur in one Step-
Wave cycle. The more steps, the more complex the Step-
Wave waveform will be.
[Range] 2, 3, 4, 6, 8, 12, 16
Knob 3
[ Turn] Step Wave Slope
Specifies the type of slope to occur between each Step-
Wave step.
[Range] off, Up, Down, Up&Down
• off ... No slope is used between steps, thus pro-
ducing a waveform that is more rectangular or
sample-and-hold like.
• Up ... Higher "Value" settings (Knob 5) produce a
longer slope only at the corresponding step,
creatuing a rising sawtooth type waveform.
• Down ... Lower "Value" settings (Knob 5) produce
a longer slope only at the corresponding step,
creatuing a downward sawtooth type wave-
form.
• Up&Down ... All steps are connected by slopes,
producing a triangular type waveform.
[ Press] RANDOM
When this knob is pressed the "Value" settings (Knob 5)
for all steps are randomly generated. The results are con-
firmed and entered when the knob is pressed a second
time or you switch to a different display.
