K2500/K2600 vs. K2000
What are the main differences between the K2000 units and the later K2500/K2600/K2661 models?
The K2500 & K2600 Series have evolved from the original V.A.S.T. technology developed for the K2000. The following list will give you an overview of the main differences between the K2000 and its successors. For additional differences between the K2500 and K2600 see here.
(The comparisons below also apply to the K2000VP and K2vx, which have the same functionality as the K2000.)
K2500/K2600 series vs. the K2000 series
- 48 voices vs. 24 voices
- 256K (K2500)/486K (K2600) battery backed RAM expandable to 1280K (K2500)/1503K (K2600 : K2661 stock),vs. 120k expandable to 760K.
- 128MB sample RAM vs 64MB
- 8 channels (K2500)/16 channels (K2600) can be used to play "drum" programs (programs with more than 3 layers) vs. only one channel for "drum" programs. 8 channels available for the K2000 when both the PRAM option and v3.54 (or later) operating system installed.
- Brighter, fluorescent LCD display on the K2500/K2600.
- Drum samples in the K2500/K2600 are new and improved.
- The K2500's daughter board, which holds the ROM blocks, includes a new 4MB stereo piano sample. (This ROM block is included standard in the K2600).
- The K2500's KDFX option offers a whole new level of effects capability and programmability (KDFX is standard on the K2600).
- The K25/26's DMTi option gives you 8 channels of digital output plus ADAT or DA-88 compatibility. K2661 has built in ADAT interface (no DMTi support)
- Sample-while-play on the K2500/K2600 allows full resampling capabilities. You can sample while playing anything on the keyboard, or sample a sequence being played in Song Mode.
- The K2500/K2600 has flash ROM, so you can update the operating system via floppy disk or files downloaded from a internet instead of having to swap out chips.
- The initial attack segment for the Amplitude Envelope can be set to increments smaller than 20ms. For the K2000, the first amount after 0ms is 20ms.
- Setup Mode has 8 zones vs. 3 zones in the K2000.
- The K25/26 allows for continuous control of any start point between Start and Alt points of the sample. The K2000 only allows switching between Start and Alt.
- The K25/26 sample skipping feature allows samples to be transposed up twice as far as in the K2000.
- The K25/26 has a powerful arpeggiator with many programmable parameters.
- Live Mode feature allows you to send external audio in through the sample input for real time V.A.S.T. and effect processing, without having to sample first.
- KB3 Mode gives you the ability to create organ program which model the way a real Hammond B3 works.
- K25/26 supports hard drives up to 8 gig, using up to 4 partitions of 2 gig each. K2000 does not support partitions and therefore can support drives only up to 2 gig.
- Triple Mode Feature (K2600 only) offers a whole new level of V.A.S.T programming.
- For the Keyboards: K2500/K2600 has far more physical controllers: 8 sliders, two ribbon controllers (single ribbon optional on K2661), 4 switch pedal inputs, 2 continuous controller pedal inputs, two buttons, breath controller input, two wheels, and aftertouch. K2000 has 1 slider, 2 switch pedal inputs, 1 continuous controller pedal input, 2 wheels, and aftertouch.
