2 LushOne 301 –LushOne Inca
Inca - Introduction
•Additional module to the LushOne base
–Joystick controller
–New ways to combine signals
–Percussive and random effects
–Scores of new patches when used as a second or third module in a
LushOne system
•Signal mixer and voltage processor
–Mix or modify signals by summing, scaling and offsetting
•Noise source
–Random voltage source and percussive sound
•Sample and Hold
–Capture and hold voltage levels from clock
•Low Frequency Oscillator (LFO)
•Analogue thumbstick with switch
•3.5mm mono Break-in/Breakout

In this teaching module
Joystick
•Using the joystick
•Using one input of the mixer as a signal processor to manipulate a
control voltage (CV)

5 LushOne 301 –LushOne Inca
Joystick
•Fun way to “perform” by
manipulating two control voltages
•X Out and Y Out go from 0V to +5V
based on the joystick position
•Button Out goes from
0V (joystick not pressed) to
+5V (joystick pressed)
•Connect through the Mixer/Signal
Processor to change range of
polarity of outputs
•The joystick makes me smile

“Gate In” can be connected to one of:
1) 5V for continuous operation
2) Button Out for control by Joystick
3) LFO Square Out for regular beats

Joystick Patch
•Patch the system and adjust
the settings as shown
•Twiddle joystick to get wide
range of weird sounds
•Try different wave shapes
•Try connecting the “Gate In” to
other sources:
–“Button Out” on the joystick –
press joystick for sound
–“Square Out” on Inca LFO for
repeating bursts

Adjust for some
“bite”
Twiddle joystick
No keyboard
needed!

CV processing with the mixer/signal processor
•The current patch gives the joystick control over
the full range of both oscillators
•What if you wanted to reduce the range of
OSC1 so you got finer control?
•Using the Mixer/Signal Processor as a signal
processor you can manipulate control voltages
to:
–Control the gain
–Add or subtract a voltage offset
–Invert the polarity of a signal
Or any combination!

9 LushOne 301 –LushOne Inca
CV Processing Configuration
•To manipulate a CV connect it to
one input
–Use a non-inverting or inverting
input
•An inverting input will create an
output voltage that reduces as the
input voltage increases
–Any of the non-inverting or
inverting inputs can be used
•Typically you want a control voltage
output to use the DC (Direct
Current) output
–DC out preserves the absolute level
of the signal and allows you to add
offsets
–Allows control voltages between 0V
and 5V
–AC output will go negative
•Use the two LEDs to monitor the
output voltage (see next slide)

10 LushOne 301 –LushOne Inca
Mixer/Signal Processor –Signal level LEDs
•LEDs light up when DC output voltage is
positive (upper LED), or
negative (lower LED)
•LED brightness goes from dim (near 0V) to
bright (at 5V)
•DC signals will cause steady lights
Slow AC signals will cause flickering lights
Fast AC signals will cause steady lights
again (due to persistence of vision hiding
the fast flicker)
•With practice you will learn to infer the
signal behaviour from the pattern of the
lights
DC Out = +1V
DC Out = +5V
DC Out = -1V
DC Out = 0V
DC Out = -5V
