Choose the model that’s perfect for churches, schools, clubs, or just relaxing at home. Their compact size, light weight, and optional wood stand will fit anywhere and everywhere.

Famous Kurzweil Sound

Kurzweil’s triple-strike 3-layer piano sound has helped to make Kurzweil professional synthesizers world famous since 1982. Kurzweil Mark Pro pianos use this same technology to offer the best piano and other instrument sounds available in any digital piano. Additionally, pro level reverberation and chorus effects offer a room-filling, concert-halt playing experience.

Stylish Design

The Mark Pro S line uses a thoughtful, elegant design of cabinet, music stand, and button panel that will please the most sophisticated player. The light weight and choice of tabletop or console style will appeal to the most practical minded.

Expressive, Natural Touch Keyboard

All Mark Pro models feature real hammer-action natural touch piano keyboards. The touch response is adjustable 7 ways and its exceptionally wide dynamic range goes from the softest intimate pianissimo to the loudest reverberant fortissimo.

Layer Function

The MarkPro TWOiS allows any two instrument sounds to be played together using the Layer function. Combinations such as Piano and Strings, Organ and Choir, and others are readily available. The Mark Pro TWOiS can also split its keyboard and play different sounds for left and right hands. The possible combinations are near limitless!

Metronome and Recorder Functions

The MarkPro TWOiS has a built-in, fully adjustable Metronome. The 2-track Recorder function lets you record, overdub and save your performances.

Convenient Computer Connections

A USB connection provides simple connection to a computer or laptop for use with any music software. No software driver is necessary. Conventional MIDI In and Out jacks are also available for easy connection to other MIDI equipped instruments.

Optional Stylish Wood Stand

With the optional matched stand (sold seperately), your Mark Pro S piano becomes a fully integrated, beautifully designed console piano. Still its light enough to be moved as a unit or, thanks to thumbscrew attachments, may be easily disassembled again.

What pedals can I use with my Kurzweil instrument?


Switch Pedals

A foot switch pedal from any manufacturer is compatible with our keyboards. Japanese pedals are wired in reverse polarity from American pedals. But all our products check the pedal polarity on power up and reverse themselves if needed, so as long as the pedal is plugged in before you turn on the unit, any pedal will work (be certain to not step on the pedal during power up as this can interfere with the auto-calibration).

In addition, some keyboards use mono jacks for each switch pedal input, whereas other keyboards use a single stereo jack for two pedals.

The PC3 Series, K2 Series, K1 series, PC2 Series, SP2 Series, SP5, PC88, and KME61 use mono jacks for each pedal. The standard single pedal available from Kurzweil is the KP-1.

The SP4, SPS4-8, PC1, SP3X, SP76/88 Series, Rumour/Mangler, Mark ProOneiS, Mark ProTwoiS, RG Series, and Troubador use a single stereo jack for dual pedal units (not sold by Kurzweil). It is still possible to plug a single, mono plug pedal into these units but you will only have access to one of the pedals. If the pedal is plugged in all the way, it will be the Left pedal, and if the plug is pulled out slightly, it will be the right pedal. A stereo (M) to dual-mono (F) “Y” adapter can also be employed to permit the use of two, single pedals.

Continuous Controller Pedals

Our keyboards require a pedal with a TRS 1/4″ connector and 10k linear potentiometer. Most manufacturers EXCEPT Yamaha and Korg make pedals with the same specifications and should work. Yamaha and Korg pedals typically use an exponential potentiometer and therefore will not work correctly. The CC-1 pedal is available from Kurzweil. You can order a pedal through your “local Kurzweil dealer.

CC-1 Wiring Spec

The Control Pedal must be wired to a single stereo (TRS) 1/4″ plug as follows:

  • Wiper to tip connection of 1/4″ plug
  • Top end of resistance element to Ring connection
  • Bottom end of resistance to Sleeve connection

I am having difficulties getting my Windows PC running Vista/Win7/8 to output MIDI to my Kurzweil via USB. Do I need to install a driver?


No. The current line of Kurzweil products have a standard class-compliant USB-MIDI implementation. They do not require the installation of any additional drivers.

Some background to be aware of:

Microsoft has been steadily REMOVING MIDI FEATURES from Windows since Vista. In Windows XP, Microsoft provided a MIDI Mapper control panel which allowed end users to select a MIDI output device. Since Vista this has not been available. As such, certain apps (like Windows Media Player – WMP) can no longer play MIDI songs triggering external MIDI devices because WMP is only routed to the internal Microsoft GS Synthesizer.

This means the MIDI app you choose to use must natively offer its own built-in MIDI mapping abilities OR you could possibly install a 3rd party MIDI mapper whose purpose is to replace the MIDI routing abilities removed from Windows. Fortunately,
these days, most commercial MIDI software products for PC, such as Cubase or Cakewalk, have a configuration screen which includes the MIDI device mapping necessary to route to an external MIDI device.
