NEBULOPHONE

Code v02 Hardware v03
The Nebulophone turns on when a mono 1/4” Jack is inserted.
Filter
The more light hitting the photocell, the higher the cuttof frequency of the lowpass
filter. Don't be afraid to move the LED!

When the switch is set to “lead”, the arpeggio's speed is freely controlled by the
knob.
In “follow”, speed is controlled by the incoming IR signal. Turning the knob
changes the speed in relation to it, stepping through single, double, triple, and
quadruple speed
Speed is controlled by turning the knob inside the first 3 modes. “Arpeggio speed”
yields a dupal or triplet square wave based on the arpeggiators speed.
In “solid”, turning changes the brightness of the LED.
The photocell can be moved to change the cutoff of the filter. More light yields
higher frequencies.
Turning the waveform knob inside each mode changes the note's decay.
Pushing the shift button steps through two different temperment with
three ranges each.
Controls the glide, aka portamento.
Both Buttons
Pushing both buttons at the same time activates Hypernoise2000 mode, changing
the Arp pot to control sample length on the left half and clock divider on the left.
Pressing both again goes back to normal operation.
