"Cosmetically, this unit is extremely unique. It has been painted purple with yellow trim, with a large vintage Batman sticker placed central to the back of the enclosure on top of additional purple-painted tape. The knobs have also been painted purple. There is a fair bit of honest wear across the enclosure, but nothing extending beyond minor nicks and dings. Additionally, some of the yellow spray paint extends to the upper two octaves of keys and cheek."
"The KiwiSix upgrade significantly expands overall functionality and mitigates several issues common to the PolySix, including replacing the original KLM-367 circuit board; which are frequently corroded due to the frequent failure of the original nickel-cadmium batteries. The KiwiSix upgrade also provides 512 tone slots, all able to be stored/edited, with 64 preloaded tones. Sequencing capability is increased; 8 separate 124-max step sequences can be edited and stored. Additionally, the KiwiSix enables MIDI functionality, with the ability to independently set the MIDI In & Out channels. The Arpeggiator and Sequencer can both output MIDI, and the Sequencer can be entirely dictated by MIDI input. The internal clock hardware has been overridden and expounded upon; now able to clock the Arpeggiator and/or Sequencer and can optionally generate a MIDI clock. Key Transposition augmentation allows transposition from 1 octave down to 2 octaves up."
