The performance controller at a glance

The Kurzweil PC4-7 is a successful combination of synthesizer, sequencer, master keyboard and controller. The 76-key action keyboard is semi-weighted, velocity-sensitive and produces aftertouch. With four synthesizers, Dynamic VAST, 6-Operator FM, KB3 and VA1, the PC4-7 offers a tremendous selection of excellent sounds to rival any workstation. With over 1000 factory sounds and 4096 memory locations for your own sounds, you can draw from the full range. For multi-programs there are over 50 Factory combinations and another 4096 for User combinations. The sounds of the PC4-7 can be further refined with 32 different effects, including reverb, chorus, tremolo, delay, distortion, EQ; which can also be used and stored with several in an effect chain. The high polyphony of 256 voices is sufficiently dimensioned so that no decaying note is swallowed even when playing faster. This also benefits the 16 parts of the internal sequencer, with which professional sounding songs can be created on the PC4-7 alone.

Kurzweil PC4-7 Control Area

High operating comfort

The name PC4-7 actually stands for "Performance Controller", and the device more than lives up to this claim, because nine buttons, knobs and faders in the control area allow direct access to sound-relevant parameters of the sounds selected for each part, respectively their synthesis model. Furthermore, each of the 16 parts has its own arpeggiator and a riff generator, so basslines, melodies and the appropriate accompaniment can be created in no time. The PC4-7 is also a 16-zone MIDI controller, which is perfect for external MIDI equipment such as an expander and for controlling sounds in the DAW. The controls of the control section can be assigned matching. For the keyboard there are different split and layer modes, which even allows layering of multiple sounds including distribution across the whole keyboard. Despite its many functions, the PC4-7 is easy to use, thanks in part to the large, graphics-capable display, the category keys and, of course, the control section.

Professional connections

In addition to the input for the power supply, there are connections for volume and two CC pedals, as well as the included sustain pedal. Two stereo output pairs connect the instrument to a mixing console, audio interface or sound system. The stereo input is designed to connect eg. a smartphone or CD player and integrate the music from it into the exercises. The headphone output allows undisturbed playing and practicing at any time of the day or night. The USB port allows the PC4-7 to be connected to a computer and used as a master keyboard with music software (DAW). The MIDI inputs and outputs allow interaction with other MIDI equipment such as a sound expander or a sequencer. A special port is reserved for the separately available ribbon controller, which adds expressive articulations to the game.
