Memo Tab / Patch Saving 

Memo Tab (and CV Tab) contain a memory chip that enables Arpie patches to be 
saved and recalled later. 

 

A total of 16 snapshot slots (i.e. “patches”) ca

n be stored.  

To save the current Arpie state as a patch, press down HOLD, then quickly press 
PLEN. The screen changes to show the slot status (used slots are lit up brightly). 
Press one of the slot buttons to save the current Arpie state to that slot. If there is 
already data in the slot it will be overwritten. You can save to multiple slots without 
having to press HOLD+PLEN again. Press a menu button (e.g. PATN) to exit from 
patch save mode. 

To load the Arpie state from a previous patch, press down HOLD, then quickly press 
PATN. The screen changes to show the slot status. Press one of the brighter lit 
(occupied) slot buttons to load the Arpie state from that slot. The HOLD LED will 
automatically be engaged when the patch is loaded, so that the chord saved with the 
patch is not lost. You can press HOLD again to exit hold mode and clear the chord. 
To exit from the slot status display without loading a patch, just press another menu 
button (e.g. PATN) 

To clear one or more slots, press down HOLD, then quickly press MODE. The screen 
changes to show the slot status. Press one of the brighter lit (occupied) slot buttons 
to clear it. You can clear out multiple slots without having to press HOLD+MODE 
again. To exit from the slot status display just press another menu button (e.g. PATN) 

Tip: The last patch slot to be loaded from or saved to will blink more rapidly than 
other occupied patch slots. This helps you quickly find the correct slot when saving 
an edited patch. 

Note: holding the HOLD button for a couple of seconds will activate the hold second 
function (LED starts blinking) after which the shift function is cancelled

 this means 

that to access the Memo Tab functions, the second key must be pressed immediately 
after pressing HOLD.
