K2600/2661 vs K2500
What are the main differences between the K2500 and K2600/K2661 models?
The following list gives a comparison of the feature differences between the K2600 and K2500 series products.
K2600 series vs. the K2500 series
- KDFX is standard vs. being an option
- The 4 Meg Stereo Piano ROM block is standard vs. being an option
- The K26 models has room for 2 additional ROM blocks, from a selection of 3 possible options: SD Piano, Vintage EP ROM, and GM ROM* (these are in in addition to the Contemporary and Orchestral ROM blocks). As a result, the K2600 daughter board is different from the K2500 daughter board. The K2600/2661 both ship with the Contemporary and Orchestral ROM blocks included. (*The K2661 includes its own built in GM ROM expansion set.)
- 486K battery backed RAM expandable to 1503K vs. 256K expandable to 1280K (the K2661 comes with 1.5Mb PRAM built-in)
- Ships with 64 MB of sample RAM vs. 4 MB for K2500s with sampling included or 0 meg for K2500s without sampling included (the K2661 ships with 128Mb)
- NewTriple Modular Processing feature available only for the K26 models, offers the ability to chain three layers of VAST processing, expanding V.A.S.T.'s capabilities almost infinitely.
- Balanced Analog Outputs vs. Unbalanced Analog Outputs. These balanced outputs are also improved so that they are hotter and cleaner and have less distortion.
- As a result of having balanced outs, the insert ability of the K2500 separate outs is not available in the K26 models, and the Mix Outs function differently. For more on this, please see the Routing Programs to the Individual Analog Outputs tutorial.
- 48 dB of resonance for filters vs. 24 dB of resonance
- 16 "drum" channels (for playing programs with more than 3 layers) vs. 8 "drum" channels
- ROM blocks, PRAM, and SIMMs are user installable on the K26 models vs. service center installation for the K2500.
- Increased amount of Flash ROM in the K2600 allows for additional features and enhancements in the future which will not be available for the K2500.
- The Digitech effects processor used in the K2500 is not included in the K26 models. However, the K26 models feature software which will convert (when loading from disk) programs from the K2500 and K2000 which use the Digitech effects, automatically creating KDFX settings which mimic the Digitech effects.
- Digital Input-Output option for the K2600 allows the ability to input 8 channels of digital audio for V.A.S.T. and KDFX processing(in conjunction with the DMTi option). The K2661 provides this via a built-in ADAT interface.
- All new preset Programs and Setups take advantage of all 8 sliders on the K26 models, allowing for incredible real-time control over your sound.
- New Interactive Setups use Song Mode and/or the Arpeggiator to create grooves that can be played as auto-accompaniment along with melody.
- Longer life lithium "coin" type battery vs. 3 AA batteries
- Display contrast adjustable via hardware switch vs. adjustment via software.
- K2600 units offers two 72 pin slots for SIMMs (this is the same as found on newer K2500s but older ones use eight 30 pin slots). The K2661 employs a single 72-pin slot
