MEMOTAB for ARPIE

This is an add-on for my ARPIE kit, and it plugs into the “hack header” expansion socket on the ARPIE main board. It comes fully assembled and tested and adds 16 patch memories to your ARPIE.

You can store 16 “snapshots” of ARPIE state (even when powered off) for instant patch recall. This functionality is also on the CVTAB except the MEMOTAB is a cheaper option if you do not need the analog voltage outputs of the CVTAB.

To be able to use the MEMO with your ARPIE, you will need firmware version 6.1. If you purchased your ARPIE after November 2019 this will have version 6.1 firmware pre-installed (check the label on the chip IC1)

For older ARPIEs you can update the firmware yourself if you have a USB TTL programmer (see below), otherwise you can purchase a replacement microcontroller chip pre-programmed with the version 6.1 firmware.

Please note that only one “tab” board can be installed on the ARPIE at a time.
