The K150 Fourier Synthesizer

The Kurzweil 150 is one of the most unique svnthesizers available on the market. The 150 is a real time additive synthesis machine with multiple resident sound blocks and extensive prograrnmability for extraordinary user creativity. It's a rack-mountable, multi-timbral sound source with 16 voice polvphony, deslgned to work with any MIDI controller.

The 22 resident voices and 69 preset programs are just the beginning. You can modify and combine them to create new programs, and save up to 186 of them in the 150's non-volatile memory. For example, vou can create infinite numbers of sound combmations. You can split a keyboard into three regions with up to seven layers of sound in each, and each sound layer may be individually tuned, transposed and balanced. Layers and regions can be copied and inserted in other locations. Combined with the many programmable modifiers, the Kurzweil 150's sound layering techniques enable you to create distmctive sounds with remarkable ease.

You can vary the overtones of each sound using Kurzweil's unique Timbre Shift- capability. You can also control how effects such as pitch bend, chorusing, vibrato and graphic equalization are applied. You can even use polyphonic afterpressure to controrpitch bend, vibrato depth and chorus detune on a note-by-note basls. The 150 Fourier Synthesizer also provides additional editors which allow you to modify velocity and loudness response, tuning intervals, program mapping and controller assignments. And, of course, the 150 has full MIDI implementation, with Omni, Poly and Multi modes of MIDI operation.

Best of all, the Kurzweil 150 Fourier Synthesizer is designed to get even better. With Kurzweil's Sound Laboratory for the Apple IIe, written by Hal Chamberlin, and additional Sound Blocks, the 150 is truly an incredible instrument for the creative musician.
