SYNC KIT PATTERN MOD
The LFO can either oscillate freely or can run synchro-
nized to the clock – this is done via the SYNC button –
the LED on indicates it synchronized. The minimum rate
of the freely-oscillating LFO is 0.1Hz, while the maximum
rate is 20Hz. When synced, the large knob acts as a
clock multiplier/divider – at the 12’o clock position it is 1,
turning it clockwise creates multiplications of x2, x4 and
x8, while turning it counter-clockwise creates divisions
of ч2, ч4 and ÷8. Please note that the multiplications/di-
visions do not exactly correspond to the numbers
around the knob.
In order to update the firmware of the PĒRKONS HD-01, remove the SD card from the synth and power it off. Connect the SD card to your computer and
place the firmware update file onto the root directory of the card. Eject the card from your computer and place it back into the PĒRKONS. Mind the
orientation - the golden pin strips should face upwards (you can see a printed icon indicating this on the panel of the synth). Hold all four voice trigger
keys simultaneously while powering on the PĒRKONS - you will see the first row of sequencer steps light up - you can release the keys once the steps
begin illuminating. Once the entire first row has lit up, the third row will light up, followed by the second and fourth rows. Once the final row has lit up, the
PĒRKONS will boot normally - the firmware update has been installed successfully!
