|The K2600 were designed as a replacement for the K2500 series. Although, these instruments share many features with the K2500 (and the K2000 series as well), many improvements and expanded capabilities were added. The stereo piano ROM block and KDFX, which are options for a K2500, are included in the K2600. The internal circuit boards were completely redesigned to improve reliability, and the audio output was improved considerably with the addition of balanced analog outputs, giving a hotter and cleaner signal. Other differences include a larger amount of battery backed RAM and room for two additional ROM blocks. The amount of space in the Flash ROM was also increased, allowing for additional features to be added to the operating system. The first of these was Triple Modular Processing, a major enhancement of V.A.S.T technology. This allows the ability to string together three layers in a linear fashion. With 30 possible algorithms for layer 1, 38 for layer 2, and 26 for layer three, this gives you almost 30,000 possible combinations - and with the variations of DSP functions available, there are literally trillions of possible combinations. So far there have been 3 releases of the operating system. The K2600 series started shipping in October 1999 with v1.03. Version 1.13 contained minor bug fixes. Version 2.0 added support for Triple Modular processing and Disk Partitioning
The K2600 is another evolution of the amazing Kurzweil Sampler - Synthesizer - Workstations. Using their excellent V.A.S.T. synthesis and a professional Sampler option (S models) and Sequencer this is truly an elegant synthesizer with a full keyboard of 76 semi-weighted keys (88 full-weighted piano style keys on the K2600X). State-of-the-art sampling is also available on the K2600S and K2600XS.
