• Patch a variable waveform oscillator into the 

AUDIO IN 1

, SAW and SQUARE waves 

work best. Feed an additional envelope or LFO to the 

pre VCA input 

on the GHOST to 

create movement. Patch the 

AUDIO OUT 1/2

 to your mixer

 

• Set 

DELAY DRY/WET

 to 80% with 

REPEATS

 around 30­40%, adjust the

 

REPEATS/tone*

 by pressing the 

R REPEATS

 knob to around 13:00 ­ 14:00. 

Sync the delay by sending a clock from your sequencer into the 

CLOCK IN

 and leave 

TIME/DIV

 knob at 12:00 

• Set 

REVERB DRY/WET

 to 60% with a moderate 

TAIL

 amount at around 40%. Adjust 

the 

PRE­DELAY

 by pressing the 

R turning the TAIL/predelay* knob

 to 

approximately 70­80% 

• Set 

DISTORTION

 to 20% and 

COMPRESSOR

 to 70% to bring in some noise 

• Send a PITCH sequence to the 

VCF CV

 input.

 COMB

 does not track 1v/oct, but this 

allows you to highlight frequencies without doubling the amplitude of the fundamental of 
the sound source. Set the 

FREQUENCY CUTOFF 

knob to 11:00 with 

VCF CV

 attenuverter 

fully CW 

• Start the sequencer and listen how GHOST creates timbres on top of a steady oscillator 

• Patch another 

1v/oct PITCH  CV

 signal to your oscillator and play around with the notes, 

you will hear how new ghost harmonies appear, let them direct your next note. 

 

FIRMWARE UPDATE 

Firmware updates are essential for any digital modules. They bring new features or 
bug fixes. 

Feel free to write any bugs, features ideas or improvements to [email protected] 

To update the firmware on your Ghost, first download the latest firmware file once 
available on Endorphin.es website: https://www.endorphin.es/modules/p/ghost 

The update procedure is done via audio: either computer or phone will work, we 
advise you to disable all notifications (flight mode) so that the update is not 
interrupted.  

1.

 

Power OFF your modular system. 

2.

 

Unplug all the cables from GHOST except a simple mono or stereo cable 
connecting the audio output from your computer headphones output to the 

‘AUDIO IN 1’

 input of the module. 

3.

 

Set the output volume of your computer to 100% or slightly lower. 

4.

 

Hold 

ROUTING

 while powering your system ON - you will see both 

CLIP

 and 

/

ENV DEPTH

 LEDs on.
