KiwiTechnics is located in Auckland, New Zealand PC Service Ltd was established in 1988 as a design and support company specialising in hardware and software. We then grew to also manufacture microprocessor based versatile LED lighting systems for use in the film industry. The name Painting with Sound was adopted when a synth repair division was started in 2006. It was during this phase that the concept of the Patch Editor was born. Combining the microprocessor and film lighting experience along with an obvious need for a replacement for the Roland PG series of controllers that are rare, expensive and in some cases poorly made, development of the PE was begun in 2008. The name Kiwitechnics was adopted for this division in 2009 as it has grown and developed a life of it’s own. The frustration of developing the PG-200 part of the PE and the obvious shortcomings of the JX-3P has led to the development of the 3P Upgrade. This began as a patch of the existing code but this quickly showed it’s shortcomings and it has now become a full cpu replacement and a complete rewrite. The Kiwisix upgrade was developed due to the steady stream of dead and dying Korg Polysix’s coming through the workshop. This was mostly due to the battery that was used starting to leak and the acid damaging the cpu board. The Polysix is a popular and unique sounding synth and should be kept alive. Following the success and the ideas developed with the Kiwi-3P Upgrade a comprehensive upgrade has been developed for the Roland Juno-106. This synth is another example of good hardware but with a limited user interface with poor midi implementation.
