6)  Release  the  encoders  and  the 
firmware update screen – Erica Synths 
BOOTLOADER  will  appear  on  the 
module. 

7)  Hit  the  PROGRAMM  button  in  the 
Updater App screen!

8)  The  module  will  indicate  the 
update  status  and  will  notify  when 
the update is completed

All  waveforms  and  snapshots  saved 
on  the  module  will  not  be  affected 
after the firmware update.

To  have  the  module  functionality 
up  to  date,  we  recommend  you 
time by time check announcements 
about  firmware  updates  for  the 
Graphic  VCO  on  www.ericasynths.
lv or on our social media.
You can update the firmware of the 
module via miniUSB cable.
To do so, follow instructions 
below:

1)  Remove the module from the rack and disconnect the PSU cable
2)  Open Google Chrome and open Erica Synths Firmware Updater App.
3)  Connect the module to the USB port of the PC
4)  Select a Graphic VCO module form the list
5)  Push and hold both encoders and connect the module to the PSU

In  the 

IN/OUT  CONFIGURATION 

MENU

  you  can  configure  CV  inputs 

by adjusting their gain, and bias. Use 
the  left  encoder  to  select  the  input 
or setting and right one to adjust the 
amount of the setting.

In  the 

CALIBRATION  MENU

  you 

can calibrate the Graphic VCO to your 
MIDI-CV  converter  or  the  sequencer. 
For calibration you will need precision 
voltage sources - 1,000V and 5,000V, 
for example MIDI-CV converter. Patch 
the  output  of  the  MIDI-CV  converter 

to the 1V/Oct input of the Graphic VCO 
and play C1 on the keyboard (it should 
generate  1V  on  the  CV  output)  and 
then  push  the  right  encoder  (1.000V 
will appear on bottom of the screen). 
Then  play  C5  on  the  keyboard  (it 
should generate 5V on the CV output) 
and  push  the  right  encoder  again 
(5.000V will appear on the bottom of 
the screen. Calibration complete!

In 

QUANTIZER MENU

 you can select 

one  of  9  preset  quantization  scales. 
Simply rotate the left menu to set the 
scale.

In 

MEMORY CLEAR MENU

 you can 

delete all user generated wavetables 
and  snapshots.  Rotate  the  left 
encoder  to  select  the  Wavetables  or 
Snapshots and push it to confirm. No/
Yes pop-up will appear to confirm the 
selection. You can not delete factory 

preset wavetables.
