Basic PC1 Features

The Sound

The PC1 offers 64-voice polyphony with balanced type stereo analog outputs. There are 384 factory programs and 128 GM programs, including Kurzweil’s stereo triple-strike Grand Piano, Rhodes and Wurlitzer electric pianos, stereo strings, brass, and Take 6 vocal samples--as well as our critically-acclaimed keyboard, guitar, bass, drums, and percussion sounds. In addition, the PC1’s Orchestral ROM includes String Sections, Solo Strings, Woodwinds, Orchestral Brass, Jazz Brass, Orchestral Ensembles, Choir, Organ, Harp, Nylon String Guitar, Orchestral Percussion, and Ethnic Percussion. There’s also room for one Sound ROM Option card, for an additional 16 megabytes of ROM sounds.

Setups make the PC1 a versatile performance instrument and MIDI control keyboard. Each setup contains four zones that can cover any part of the keyboard, or overlap across the entire keyboard. You can program each zone independently--with different programs, physical controller assignments, and MIDI channels for each zone. Using the onboard arpeggiator, you can program setups with grooves that start automatically and evolve in countless variations as you play.

Keyboard and Controllers

There are two PC1 models. Both have the same features, with only one exception. The PC1X has a fully weighted 88-key piano action, while the PC161 has a 61-key unweighted synth-style action. Both models have mono pressure (aftertouch), and have programmable velocity sensitivity. (By the way, whenever we mention the PC1 by name, we’re referring to both models.)

You’ll find the usual array of physical controllers--Pitch Wheel, Mod Wheel, continuous and switch pedal jacks, and multi-function front-panel buttons and knobs, and a unique ribbon controller. They’re all fully programmable. There’s an extensive list of programmable features for MIDI control--the PC1 isn’t just a great sounding performance keyboard; it’s a serious tool for MIDI sequencing, and makes an excellent centerpiece for sophisticated MIDI studios. The PC1 is also well-equipped to receive MIDI from other instruments or external MIDI sources like computer-based sequencers.


To complement the ROM sounds, there are over 150 multiple effects and 30 reverbs. You can apply the effects to programs or setups, and you can easily control the Wet/Dry mix in real time. You can also program the multi-effects and reverbs for even more control in performance and recording.


Sound ROM Cards

The PC1 has a socket for one ROM expansion card that you can install yourself (the expansion kits come with complete instructions). An expansion card adds 16 megabytes of ROM sounds to the 32 megabytes of onboard ROM.


The PC1 has two pedal jacks for a stereo or mono switch pedal (for functions like sustain or program/setup changes) and a continuous pedal (for functions like volume control). The switch pedal jack allows two pedalsto be plugged in simultaneously. Your Kurzweil dealer stocks the following optional pedals:

FS-1 Standard box-shaped switch pedal
KFP-1 Single piano-style switch pedal
KFP-2M Double piano-style switch pedal unit
CC-1 Continuous pedal

Ribbon Controller

There’s a dedicated modular jack (like a telephone jack) on the rear panel for connecting this 600-mm (24- inch) ribbon controller. You can configure the PC1 to use the ribbon as a single large controller, or a three section controller with independent settings for each section.

Music Rack

The sturdy acrylic music rack (model PC-MDS) fits into a bracket that you attach to the PC1’s rear panel.
