The latest in electronic instrument chip technology has been in development for several years at Kurzweil R&D in Waltham, MA. This newest sound chip is used in the MarkPro Series, creating a powerful digital piano unlike any other. Years of research and analysis have gone into the original acoustic sampling creating a chip that could play and express a majestic and deep stereo sound and provide plentiful polyphony for any home.

MarkPro TWOi

88 note fully weighted hammer action with velocity sensitive adjustable keys. The MarkPro TWOi is a digital piano of great lineage. With a sound engine derived from our 2007 Electronic Musician Editor’s Choice Award winning SP2X Controller, the MarkPro TWOi offers an array of performance features and superb sounds.

Expressive Sounds

64 expressive sounds including the award winning Kurzweil Triple Strike Grand Piano. The MarkPro TWOi boasts 64 incredible sounds, including our acclaimed Triple-Strike Stereo Grand Piano, our new lush Stereo Strings, multi-strike Classic Electric Pianos (both Classic Tine EPs and Wurlitzer(TM)), FM Electric Piano, Harpsichord, Brass Sections, Organs, Pads, Mallets, Guitars, Basses, Drums, Percussion, and Voices (featuring Kurzweil’s outstanding Take 6 vocal samples).

USB Interface With Complete MIDI Functionality

The MarkPro TWOi is a full 16 channel multi-timbral device. Built-in MIDI In/Out ports provide a convenient means of connecting to external MIDI devices, such as a computer sequencer, where all 16 channels can be accessed independently. In addition, the MarkPro TWOi supports MIDI system exclusive dumps for back-up and restore of song data and global settings.

Song Recorder

The MarkPro TWOi Recorder offers two song memories comprised of two tracks each. One of the biggest advantages in the MarkPro TWOi recorder is that not only does it record your individual solo performances, but it also records any layered and split sound combinations together into each track and even remembers real-time sound changes. As a result, the recorder can actually record and play back up to 6 simultaneous parts.

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.
