OVERVIEW

The MPS20 is the ultimate “Pro-Consumer” portable piano for the home user, studio player, student, or pro gigging musician.

The MPS20 more than doubles the amount of pianos & organs found on the MPS10. Included are 24 pianos featuring Kurzweil’s newest “Pro Piano” program. With 100 rhythms & 10 drum kits, the MPS20 goes beyond conventional piano features including a built-in library of over 200 sounds taken from the PC3 series keyboard. Included are a variety of categories, each with their own custom default voice preset. These include, electric pianos, tone wheel organs, pipe organs, strings, vocals, orchestral ensembles, synthesizers, and many more to inspire creativity.

The MPS20 is Kurzweil’s first digital piano to feature the all new LK40 GH+ Graded Hammer “Escapement” Action Keyboard. The MPS20 keyboard grades the hammer weight in 4 zones, from heavier in the bass, to lighter in the higher octaves. The action also features an escapement, which reproduces the let-off and jack engagement of a real acoustic piano.

Other step-up features from the MPS10 include a new 2-Track sequencer with 20 song presets, and a new doublewide scrolling alphanumeric display. The MPS20 adds 6 “Favorite” voice presets, rich effects, selectable touch sensitivity, split, layer, transpose and 51 demo songs. In addition, Kurzweil adds a new “Variation” button, offering subtle voice changes to your existing sound.

The MPS20 comes complete with a built-in 4 speaker, 30-watt monitor system, stereo input and outputs, MIDI, and USB. The MPS20 is housed in an attractive matte black cabinet, and comes complete with a portable music rack. Add the optional furniture-style music stand, and you’re ready-to-go for either home or portable use.

Troubleshooting

Question:
How can I restore my MP20/MPS20 to its factory defaults?

Answer:

Note: Performing a Hard Reset will delete all user-recorded songs and will restore all parameters to default values. This action cannot be undone.

There are two methods:

Power Up Method:

  1. Hold the C8 key down while switching on the power.
  2. Continue to hold C8 down until you see “RESETTING” (scrolling) in the display then release.

Function Menu Method:

  1. Press the Function button.
  2. Press either Select [Up] or [Down] buttons to move through the function menu (forwards and backwards) and locate the Hard Reset parameter:The display will show (scrolling): “Hard Reset?”
  3. Press [Next+].The display will show (scrolling): “Confirm?”
  4. Press [Next+] again to perform the reset.

Via either method, the unit will then erase its user memory, restore all factory settings and reboot.

Question:
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?

Answer:

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.
