Kurzweil K1000 AX Plus Acoustic Expander K1000AX K 1000 AX


Kurzweil K1000 AX Plus Acoustic Expander in very good condition with just some minor play wear from normal use. Excellent operating condition. Includes power cable.

The K1000 also has a very sophisticated digital/wave synthesizer engine. K1000 patches start life as a digitally coded waveform that Kurzweil calls a Soundfile. A Soundfile can be a sampled waveform (coming from Kurzweil's famous samples like piano, string, wind, etc...) or a digitally produced waveform like sine, sawtooth, or square. Then, you put Soundfiles together into the layers of a program. Effects are part of each layer as well.

The K1000 also came in a series of rackmount synths. The so-called "1000 Series" consists of no less than ten different models of the rackmount version of the synth. Each module in the series has a different set of sounds. Complicating things further, you could upgrade these modules, so that they may have one name on the front panel, but have the features and sounds of a different model from the series. Some of the upgrades include:

1000 AX Plus Acoustic Expander (185 presets - all SX and HX plus more)
1000 GX Guitar Expander (100 presets)
1000 HX Horn Expander (75 presets)
